In this clip, we will show you how to insert the gasket into the LORO-X push-fit connection. Align it on one side of the pipe, fold it inward with your index finger, press it in with your thumb and middle finger, and then align it against the inner edge. Simply press it against the inner surface — done!

Welcome to this video! I will show you how to assemble the LORO-X push-fit connection system. First, use the LORO-X lubricant. Apply a little lubricant with your finger or a brush to the inside of the gasket, and then apply a little more lubricant to the spigot end of the next pipe. Align the pipes and push them together as far as they will go. Done! Very simple. Just make sure that the edge of the gasket remains visible between the pipes.

In this clip, I will show you the different types of pipe clips. This is the standard pipe clip; the other one with the cut-out is a special pipe clip for use with branches. Let's take a look at the normal pipe clip: to install it, unscrew the clip, attach it at the socket connection of the pipe, put the second half back on, insert the screw, and tighten it with a wrench. Make sure that the gaps between the two halves of the clip are approximately equal on both sides.

In this video, I will show you how to use the clip with a cut-out for the branch. Here you can see the clip; this is the cut-out section that fits the branch. You open the clip, take the lower part, and insert the pipe connection into it. Then you take the upper part with the cut-out and the guide to the branch, insert the screws, and tighten them with a wrench. Make sure that both parts of the clip are approximately the same distance apart from each other.

In this video, we will show you how to cut a LORO-X pipe using a pipe cutter. First, mark the pipe. Then take the pipe cutter. We recommend a pipe cutter with several cutting wheels (at least three). Apply the pipe cutter and tighten it. Turn it back and forth several times to cut the first groove. Then keep turning it, tightening it regularly as you go, so that the cut becomes deeper. As you can see, sharp edges and metal shavings are produced. Don't forget to smooth the sharp edges, so that the gasket of the next pipe is not damaged when it is inserted.

In this clip, I will show you how to release the pipe connection after the lubricant has cured after one day and the connection has become very tight. You only need a screwdriver and a can of spray oil. Place the screwdriver directly against the gasket, lift it, and open a small gap between the gasket and the pipe in this way. Spray a little oil into it and work your way around the pipe several times with the spray oil. Then grip the pipe, twist it back and forth, and pull it out. Done! Please remember to dispose of the gasket, as it may have been damaged by the screwdriver.

In this video, we will show you how to fasten the pipe to the wall using a standard pipe clip. Drill a hole in the wall, insert a wall plug, and take a threaded rod and the pipe clip. Screw the rod into the pipe clip and tighten it with a wrench. Screw the pipe clip into the wall plug until it sits firmly. Open the lid, insert the pipe, and close it again. This is easier if you close the lid from below. Tighten the screw. Apply lubricant to the gasket and the spigot end of the next pipe and push it in. This is how you work your way upward.

Here from BAU in Munich, another product presentation: our ATTIKASTAR Series 93. Here we have a very large hood and thus a lot of capacity, with which we can discharge the drainage from the roof. You see an emergency drain as a siphonic system: we have a weir, over which the emergency drainage overflows and is then drawn off via the siphonic drain and our pipework system. Here we have two pipes side by side, in order to achieve a smaller intervention into the roof while still achieving a very high capacity. These large drains are particularly in demand in industrial construction or large hall construction, in order to drain large roof areas there via just a few drains.

With the LORO main drainage systems made of steel drainage pipe with push-fit connection, combining main drainage and emergency drainage in one system, many questions of modern roof drainage can be answered. Every LORO-X drainage system — whether parapet, external or internal drainage — consists of drains, fittings and pipes. Within the system, the controlled suction performance can be designed to be either strong or low, depending on whether gravity flow or power siphonic flow is desired. At the moment, the system is in the main drainage phase, in which the rainwater is discharged into the underground drain as gravity flow. During this, the water level on the roof rises to a maximum of 35 mm. This quantity of water corresponds to the inflowing rainwater quantity during a normal rainfall event. The so-called hundred-year rainfall event is now simulated by increasing the water inflow to over 4.5 litres per second. The rainwater that has until now been held back by the integrated emergency overflow weir can now flow into the emergency drainage system and drain to the outside via a separate flow path with power siphonic flow. Due to the weir patented by LORO underneath the hood, the water first backs up to the defined water level and can then be drawn off the roof in a controlled manner via the weir with strong suction performance, whereby a low water level of under 75 mm on the roof is made possible. If the rainfall quantity increases further, the strong suction performance in the closed system becomes clearly apparent. The controlled turbulence of the water-air mixture, particularly at the drain, ensures optimal suction performance. This water-air mixture is controlled primarily via the ventilation at the drain and downpipe: in order to achieve reliable gravity flow, ventilation of the drain and the downpipe is necessary. With siphonic flow, the drain and downpipe are correspondingly unventilated, so that the suction performance can build up within the closed system. At the end of the simulated heavy rainfall event, the water level on the roof drops back below the defined weir height of 40 mm, and the emergency drainage stops operating.

Here from BAU in Munich, you see a comparison of our very well-known balcony drains: the Series E and F on the one hand, and the Series H on the other. The major difference between the series: the Series E and F is a single drain that can drain one balcony and is connected to the side of a downpipe. The Series H, on the other hand, is a direct drainage system — with which several balconies can be drained via a single downpipe. The Series E and F are available in a variant with a bitumen or EPDM connection collar or with a membrane connection collar, for cold balcony installation or also for warm installation, i.e. where we have thermal insulation. The same is available for the Series H; here the series are alike. The major difference remains that with the Series H we can drain several balconies via a single downpipe. You can also purchase the Series H, as well as the Series E and F, from us as a side outlet drain. This is then routed either within the top concrete layer or within the thermal insulation; it works according to the same principle. There is an important difference between the Series E and F: Series F always means that we have an extension element. So if we have paving slabs on pedestal supports, or timber decking, for example bangkirai, we always use the Series F. This allows us to drain both drainage levels, as required by DIN standards and the relevant technical rules: the upper paving level as well as the lower level, because the water can pass through our strainer unit at the top. Furthermore, as standard, we have the strainer unit sitting directly on the drain body. With the Series H, only the variant with the tall extension element is available here, as shown. In the extension element, there is also a ring strainer at the top, through which the pipe is routed from above. Those are our balcony drains, Series F and H, in comparison.

I'm René from LORO, and I will explain something about our new Series H. Here we have our well-established Series H, a direct drainage system: our pipe comes from the storeys above through our strainer mount. Brand new on the Series H is our new drainage ring, which you can see down here. In the old variant, the water ran underneath the drainage ring. From a stability standpoint, we considered how to improve the product and make it more innovative — and that is how our new drainage ring came about. We take the pipe out: the strainer mount has essentially not changed compared with the old product. What is new is the drainage ring. You can see that, with its contour, it sits properly within the sealing ring, or rather the clamping ring, in which our membrane is also clamped, making it very stable. When I have paving slabs with relatively tall build-ups, we get good stability here: the drainage ring sits securely within the clamping ring and does not slip out. If maintenance needs to be carried out, we can simply go in with a screwdriver and remove the drainage strainer, in order to carry out maintenance on the drain. That is the innovation we now have with the Series H. The water quantity benefits too: thanks to the contour we have created, we now get even slightly more water through than with the old ring. We now have fine ribs, and the intermediate ribs also serve to provide additional stabilisation. Furthermore — unlike with the old product — we can screw our strainer unit in place, so that height adjustment is always possible. The product is cut to length in the usual way with a cutter knife or a standard commercial saw; of course, you can also use an angle grinder on site.

Welcome from BAU in Munich. Here we are presenting our Series GF drain, a direct balcony drainage system. The drain is made of galvanized steel. Here we have a collar, which can later be sealed with liquid plastic when the balcony is waterproofed. The drain can be installed in cast-in-place concrete as well as at the precast plant, and is sealed later on site. It is a direct drainage system: with the Series GF, balconies located above can also be drained directly. For this, we have our strainer unit to compensate for the height offset of the paving, so that we can drain both drainage levels, as required by the standard — that is, the upper level from the paving and the lower level via our strainer unit, where the water passes between the slabs and is discharged into the Series GF.

Here from BAU in Munich, we are presenting our Series J drain. The Series J drain is a direct drainage system, but it can also be installed as a single drain — particularly in renovation cases, since with the Series J we only need a single core drilling. The drain is fitted at the top with a flange, which is sealed using liquid plastic. Below that, we have a thread and a socket. The drain body is simply inserted, closed or secured by means of the socket, and later sealed with the liquid plastic. This creates a fast pipe connection, and the system can be installed relatively quickly on site.

Here from BAU in Munich, you see our Series V. We now also offer the Series V in a brand-new DN 100 variant; until now we only had it in DN 70. The Series V was designed for situations where, at the start of a project, it is not yet exactly clear which waterproofing membrane will be used — simply to have a bit more flexibility. We have attachment elements for plastic, seen here in our V-FL, as well as our V-AK for corner installation, where we have an axis dimension of 95 mm from the pipe. This is particularly important on small balconies, so that the pipe does not protrude very far into the balcony. We have developed a wide variety of attachment elements for the Series V. The Series V consists of a stainless steel base body. This base body is installed with the help of a formwork bell and a formwork cone, either at the precast concrete plant or directly in cast-in-place concrete on site. The Series V is also available in a variant with a fixed flange construction, which allows the waterproofing to be clamped in place. Furthermore, there are attachment elements for single drains or for our direct drains with a pipe cut-out, through which the pipe from the balcony above is routed. This makes it possible to connect and drain several floors together. That is our Series V in DN 70 and DN 100.

Here from BAU in Munich, a brief explanation of our emergency drainage unit for the Series E and F drain body. The emergency drainage unit is simply fitted onto the round body of the Series E and F. This gives us the option of implementing emergency drainage in the balcony area with a damming weir. This emergency drainage unit also has an extension strainer at the top, so that we can install it within the paving as well, keeping it accessible for maintenance purposes — allowing us to carry out our biannual inspection here too. The unit can be inserted into both the vertical and the horizontal variants of the drain body. This way, we guarantee sufficient emergency drainage for the balcony area as well. In our emergency drainage unit, there is also a cover above the weir, so that rainwater dripping in from above through our cover strainer cannot flow directly into the emergency overflow. This means the emergency drainage on the balcony must rise, flow over the weir, and only then drip away to the outside via the pipework system. Thanks to this cover, no water from above reaches the damming element directly — which is the problem with many emergency overflows on the market.

Welcome from BAU in Munich. Here we are presenting our new Series IV. Our Series IV combines the advantages of our previous Series I and our Series V in a single product. The Series IV is specifically intended for use at the precast concrete plant. With the Series IV, we have a galvanized steel base body with an epoxy resin coating on the inside and outside. The drain can be installed at the precast concrete plant, and then, on the construction site, the strainer is simply inserted, into which the pipe is later placed. This means that at the precast concrete plant, there is no longer any need to pay attention to the orientation of the retaining lugs — we can determine this later on site, i.e. the angle at which the pipe is threaded in. With the Series IV, you simply fit the ring strainer over the pipe, align the two retaining lugs towards the wall, let the pipe slide in from the side, straighten it up and slide it onto the socket. The pipe is secured via the drainage ring. This creates a firm pipe connection, and no pipe clip needs to be fitted in this area. That is our new Series IV.

Until now, we have had our Series IV in the DN 70 and DN 100 variants; now brand new also in DN 50. The Series IV has the ring strainer sitting on top, and we now have our newly developed drainage ring. The advantage over the commercially available series, which has already been installed in precast concrete elements in Germany for decades: we no longer have fixed retaining lugs. With our drainage ring, we now have the option of determining the orientation of the retaining lugs later, on site. This means that the basic unit of the Series IV is installed at the precast concrete plant, and the drainage ring is added later. We align the two retaining lugs towards the wall and can then insert our pipe. Apart from that, the product does not differ from our other variants. With this, we hope to have developed a great product for the market. The Series IV is now available in DN 50, DN 70 and DN 100.

Here at BAU in Munich, we are showing another product: our Series 62, an inlet body with no intervention into the roof. This means the hood floats freely above the waterproofing membrane, and we have no drain body that intrudes into the thermal insulation. Because there is no intervention into the roof, we can also use this drain on inverted roofs. We can use it on roofs that have no thermal insulation, or on large roofs with zero-degree slope, in order to carry a good amount of performance away from the roof. The Series 62 has a drainage capacity of 14.5 litres with the DN 70 pipe. This high drainage capacity is achieved with the siphonic drain via the connected downpipe, which is routed down the building and then has an outlet onto a surface that can be safely flooded without causing damage. The Series 62 is available in various parapet variants: one for 45 degrees for bituminous waterproofing and one at 90 degrees for membrane roofs.

Here from BAU in Munich, we are presenting our Main-Emergency Combi system, the LX772. This is a combined drain in which the main drainage is discharged via the DN 100 pipe and the emergency drainage via an internal DN 50 pipe in a siphonic drainage variant. In the integrated T-piece, you can see how the pipe bend from the DN 50 pipe is routed all the way down and, at the end of the standpipe, opens into an outlet piece. The Main-Emergency Combi has a main drainage capacity of 4.5 litres and an emergency drainage capacity of 8.2 litres. This makes it well suited for installation on green roofs, where emergency drainage requirements are a factor higher and more water accumulates, while the main drainage requirement is somewhat lower. This means you can drain relatively large roof areas via just a single drain. For example, you save on two DN 100 spouts, which also saves costs. The Main-Emergency Combi is installed at the parapet, and we offer various variants for this. Here you see a variant that is installed 30 cm away from the parapet. We also offer the drain as a fixed-point/sliding-point construction with a 90-degree upstand for membrane waterproofing, and with a 45-degree upstand, i.e. with a clamping flange, for bituminous waterproofing. An inspection chamber can additionally be placed over the Main-Emergency Combi, which prevents the green roof planting from reaching the drain and substrate from being sucked in. Our Main-Emergency Combi has an intervention depth of 106 mm into the roof; we need thermal insulation of at least 160 mm to install the drain body. By comparison, here you see our Flach 50 version: there, we would only need an intervention depth of 50 mm into the roof, or thermal insulation of 120 mm. Both Main-Emergency Combi variants are particularly well suited for renovation projects, since we only need a single core drilling through the parapet and no second core drilling for the emergency drainage. Please feel free to contact your local technical advisor.

Here is another new product from LORO: the rectangular emergency drain spout, which is now also available in several diameters. The DN 100 variant was already on the market; now further nominal sizes are being added, for example for balconies. These rectangular spouts have been requested very often, partly because they integrate very well into brick façades. In this context, we can point out that it is certainly possible to enlarge the dimensions — for example, to the width of a brick, so that the outlet of the spout blends harmoniously into the brickwork pattern. The emergency drain spouts can also be manufactured in different lengths depending on the specific project, according to how your façade looks: whether you have an external thermal insulation composite system or a brick veneer wall. As mentioned, on request also in different lengths and, of course, different dimensions. It is always ensured that the cross-section of the spout corresponds to the cross-section of the pipe — it can certainly be larger in the case of custom manufacturing, but never smaller than the pipe cross-section.

Here we explain our cascade drainage system and what pressurised gravity flow is. In our cascade drainage system, we need pressurised gravity drainage in order to route the water from a DN 100 pipe through a DN 50 pipe. With setback storeys and terraces, there is usually very little space available. At LORO, we do this by installing a gravity-flow drain at the top of the roof; below it we have our DN 100 downpipe. Inside it, we build up a water column of 2.50 m — that is the minimum water height we need. So we require a minimum storey height of 2.50 m in order for the water build-up to be achieved. In the area of the setback storey, we want to have only a single DN 50 pipe for this pressurised gravity drainage, whether it is routed within the thermal insulation or between the paving slabs and the upper waterproofing membrane. The reason is the space requirement: since we have a pipe-routed system, we want to route the DN 50 pipe through here, and this is only possible with pressurised drainage — that is, via the 2.50 m water build-up, with which we push the water through the DN 50 pipe. At the T-piece, our DN 50 pipe arrives from the setback storey, enters the downpipe and ends there. A ventilation piece sits on top, with which we ensure the air-water ratio in the downpipe, in other words we ventilate the downpipe. The water coming out of the DN 50 pipe is released from pressure, and we once again have gravity-flow drainage. It must be taken into account that we can discharge a maximum of 4 litres per second in the DN 50 pipe, with a maximum pipe offset across the setback storey of 8 metres. Those are the maximum values. Usually there is a recessed setback storey, or even several cascades that step down from the roof across the individual terraces. The pipe has to be routed from the roof all the way down into the ground, and this can be solved well with our cascade drainage system: at the top, it starts with a drain installed on the roof. We then come down with our pipework system to the first setback storey, the first section of the cascade, and the pipe is routed to the next drain. The special feature here: we route the pipe through the drain and feed the water from the roof area directly into the pipework system after the first setback storey. This means there is no contact between the water from the main roof area and the next setback storey. The water that accumulates on the terrace flows via the drain into the DN 100 pipe, and in the downpipe all the water is reunited. This can be built up in this way until, for example, you have ten floors, with a maximum of 4 litres per second. There are various variants available here: we can also work with a grating, and we offer the drain within the thermal insulation or as a parapet drain. With a classic parapet drain, we use our fixed-point/sliding-point flange construction, which is the best type of connection between the roofing membrane and the drain. In the middle, the DN 50 pipe protrudes, to which you can connect the pipe from the storey above. The pipe then passes through the parapet, and the system can be built up again as shown in our detail drawing. Those are the various types we offer. Please feel free to ask our local technical advisors — they will be happy to help and design the system for you.

With the LORO-X DUOSTREAM cascade drainage system, the roof area and the roof terrace areas below it are drained using just two collector pipes — one for main drainage and one for emergency drainage. A drain with gravity flow is used on the roof area. The branch fitting, which is fitted with ventilation openings at the top, ensures on the one hand the ventilation of the gravity-flow drainage of the drain and, on the other hand, the venting of the downpipe under pressurised gravity flow. The horizontal offset from the downpipe to the ground-floor drain runs, in this case, above the waterproofing membrane. Alternatively, the collector pipe can also be routed within the thermal insulation; LORO offers a special drain for this that makes this routing possible without any problems. In this case, the special pipe penetration with deflection within the thermal insulation is used. On each roof terrace, the inner pipe, with pressurised gravity flow and increased flow velocity, is deflected into the following downpipe in the special branch fitting with integrated bend. In order to be prepared for any possible backflow from the underground drain, a high-performance safety overflow is installed at the end of the first stream for main drainage. In the second stream for emergency drainage, the drains from the roof and from the roof terraces are fitted with a damming element; drainage takes place via an outlet bend to the outside. With pressurised gravity flow, a column of water builds up in the downpipe as intended. The resulting excess pressure overcomes the flow resistance of the horizontal pipe. Drainage of the roof terrace takes place by gravity flow in the separate flow path of the DN 100 pipe; only after the deflection into the next downpipe do the two flow paths merge, and the principle is repeated on the next roof terrace. During the so-called hundred-year rainfall event, the water level rises above the threshold for main drainage, so that the water can flow over the damming element of the emergency drainage. In this way, all floors are connected to both main and emergency drainage.

I'm René from LORO, and I will explain our LORO-X DRAINJET system with siphonic flow. With negative-pressure drainage using DRAINJET, we can discharge a very large amount of water via our drains. We have full-bore flow in the pipework system and can therefore discharge significantly more water via the pipe cross-section. Our system always needs a downpipe, because it is there — together with our patented hood — that we generate the negative pressure. In siphonic drainage, the water level at the main drain at the design point is 55 mm, and at the emergency drain 75 mm. With siphonic drainage, there are usually several drains — there can also be five, six or seven. The further away a drain is from the downpipe stack, the more water it would draw. That is why the drain located furthest from the downpipe gets a larger pipe, and the drain sitting right next to the downpipe gets a smaller one. We call this hydraulic balancing: each drain gets exactly the capacity it actually needs. This can also be distinguished visually: the grey stainless steel hood is always the main drainage; on our emergency overflows, we always have an orange hood. This way, you can immediately see on the roof area which is main drainage and which is emergency drainage. The main drainage must always be connected to the underground drain or to a cistern — in other words, to somewhere the water is discharged. For emergency drainage, on the other hand, German standards require that the water be directed onto a surface on the property that can be safely flooded without causing damage. This means you route your system through the building and have a bend at the bottom — either 45 degrees, 90 degrees, or two 45-degree bends — and direct the emergency drainage water onto your property. This is how you protect your roof from collapsing. Siphonic drainage is particularly important for large hall buildings. If, for example, a large hall has an internal roof valley into which all the roof water flows, you can use our system to drain a very large amount of water via just a few drains. This is also a point of sustainability: we install few drains, thereby saving costs, and our system has very small pipes, which keeps the cross-section small and likewise saves costs. The pipework system is installed in the hall without a slope. You only need to make sure that the pipes are not laid with a reverse slope, which would cause a water pocket to form. It is also important during installation that we secure the pipe sockets in position using our safety clips. We also support planners and architects on the design side: if you give us a roof plan, we can calculate this using our calculation software. We need the pipe lengths and the roof build-up, calculate how much water accumulates, and look at where the pipe should run within the building — then we can design the system. For this design, you receive a bill of materials, which can also be used for the tender or later for installation. In addition, we can issue partial-section material lists, so that the installer on site knows exactly where the material is to be installed. A further advantage: we can pack the system by riser. If, for example, you need riser 1 on the construction site in calendar week 13, let us know; we assemble the material at our facility and deliver only the riser material for riser 1 to the construction site, where you can install it.

Here from the Dach und Holz trade fair in Stuttgart, we are presenting our new products. We have brought along our Series 49, our emergency drain in the DN 125 size, in a two-part design: the vapour barrier is clamped in the lower part, and the upper waterproofing membrane in the upper part, the extension element. The Series 49 is designed for very high drainage capacities. That means we have a lot of emergency drainage on the roof, and with the Series 49 as a vertical drain, we can discharge a very large amount of emergency drainage. Here we have installed our patented hood. Our hood is relatively large — what we do not have, however, is a high water level. We have a very low water level of a maximum of 75 mm. The water is drawn in by the drain and passes over the weir; this way, we limit the water level at the drain to 75 mm. Particularly in industrial hall construction, i.e. with trapezoidal metal roofs, the weight on the roof must always be taken into account, so that the hall does not collapse. With the LORO system, we always have a limitation of the emergency drainage water level to 75 mm.

Here from BAU in Munich, we are presenting our DRAINJET Mini drain, which we offer in the DN 50 or DN 70 variant. The DRAINJET Mini is suitable for installation in a box gutter of at least 150 mm, or also 300 mm. You can install it in a box gutter in front of the building, or also on the inside of the parapet. It is available both as a main drain and as an emergency drain with an integrated weir. With the emergency drain, the usual approach from the gutter — having the drip edge at the front — is no longer needed. The emergency drain is discharged in a targeted way and can therefore be routed out cleanly at the bottom of the façade. The DRAINJET Mini ensures a very clean appearance of the façade without visible pipes. We have shown this in our brochure: the pipe can be routed all the way down within the ETICS, the external thermal insulation composite system, meaning there is no pipework visible in front of the building. Thanks to the small cross-sections of the pipe — DN 50 and DN 70 — it is particularly well suited for this installation within the external thermal insulation composite system.

Brand new, we now have our composite sheet metal drains. We have never had anything like this in our range before, and nothing like it is known on the market either. We have developed a new process with which we can press our composite sheet metal — which we receive in a cut form — into the pipe contour of the stainless steel pipe here at the bottom. The advantage: wherever the drain is needed, you can simply approach it with the connecting membrane and fix it to our composite sheet metal using a hot-air gun. This already creates the waterproofing seal — quite simple and easy.

The range of standpipes: galvanized, stainless steel, copper and square, with and without cleaning opening. On the far left, you also see the safety overflow, an installation component for the cleaning opening. It ensures that, in the event of backflow from the underground drain, there is relief here of up to 9 litres per second.

From the Dach und Holz trade fair here in Stuttgart: we would like to use this fair to talk about our composite pipes. We have developed our composite pipes specifically for use indoors. This means we have condensation insulation and thermal insulation combined in a single pipe: we have our standard LORO-X pipe on the inside and again on the outside, with the space in between filled with foam. This is how we achieve the condensation insulation and thermal insulation. The LORO-X composite pipe is a socketless pipe, meaning no socket is visible from the outside; our socket always sits at the top on the connection piece. Further LORO-X composite pipes can also be connected there. For safe installation, we also offer a wide-band clip. This wide-band clip closes the gap and helps to secure the pipework. Of course, you can also route our LORO-X composite pipe through slabs. In some areas, there are fire protection requirements of R 90 and R 120, which we meet here. Please refer to our Aktuell 86 and our approval for details. The composite pipe is specifically intended for use indoors, because no additional insulation is needed there. Furthermore, we also offer the composite pipe in a Silent variant. The construction is basically identical to the standard composite pipe, except that an additional film is applied to the inner pipe. This film reduces structure-borne noise and makes the pipe sound somewhat more muffled. This allows us to reduce noise by several decibels and meet our sound insulation requirements.

It is well known that the changing requirements in the shipping industry can severely limit flexibility in the design of new ships and retrofits. Whether tanker or cruise ship – all of them are expected to carry more, travel faster and operate more efficiently. Unfortunately, higher performance comes at a price, and in view of strict safety regulations, the designer must constantly take weight and space requirements into account in order to achieve the expected performance of the ship. Against this background, LOROWERK would like to present to you a unique range of push-fit pipes that has undoubtedly revolutionised its field within the industry. The Laura product is well known in Europe and has been used since 1954 in many industrial, commercial and private applications. In 1977, the company achieved its breakthrough in the shipping market and launched a product line specifically for marine and offshore applications. In this video, we focus on these product lines. In 1963, the company developed and launched the Laura X push-fit socket, which completely revolutionised the push-fit connection system for pipework. The Laura X socket is a two-stage socket that — an auxiliary fitting is preformed at each pipe end. A tight connection is ensured by inserting a unique sealing element into the receiving socket. The Laura X sealing element is a lip ring gasket, specially developed for tightness and stability under changing temperatures and special loads. Pipe sections with plain ends are pushed firmly through the first receiving socket and into a second socket, ensuring the correct alignment of the pipe. The principles of this innovative design provided the basis for the later development of the ax socket. The ax socket was developed specifically for small ball pipelines used in ships' vacuum toilets, and is currently installed on board large luxury cruise ships such as the newest vessels of Orianna Chander, Horizon and Zenith, as well as the Carnival Cruises' Fascinator and Sensation. The sockets are single-stage. They are sealed by inserting a larger, specially made sealing element that ensures an airtight seal and maintains an operating pressure of 6 bar. Both Laura X and Laura Vac are manufactured in galvanized steel and stainless steel. The Laura Vac product range is also available in other materials to meet special requirements, such as loads. Magnetic permeability is typically associated with marine applications. Both product ranges have vibration and shock certification up to 3G and currently meet German military-technical standards [applause]. With the exception of two Nephron stainless steel pipes, both Padua types are hot-dip galvanized and fitted internally with the Rizla coating. This provides additional protection for the pipe and prevents the rapid formation of calcified layers, which reduce the inner diameter and eventually restrict it. Although the pipes are very heavy, their design has proven to be impact- and shock-resistant. The product does not break even under extreme frost conditions and can be classified as non-combustible in accordance with DIN 1986 Part 4. In the event of fire, no harmful gases are released, and thanks to the push-fit socket design, all pipe sections remain intact. The pipes are therefore ideally suited for fire protection applications. The Laura X and Laura Vac ranges are available in nominal sizes from DN 40 to DN 200. The pipe sections can be supplied with one or two sockets and are available as pre-cut sections in various lengths. Pipe sections with lengths from half a metre to six metres, comprising bends, branches, reducers and penetrations, are available with push-fit connections. Cutting to size is therefore minimal, and welding is only a fallback solution. To assemble a pipe section, simply apply a little lubricating cream to the gasket and the plain end of the pipe section. Push the plain end fully into the receiving socket and allow the cream to dry thoroughly. The lubricating cream makes insertion into the socket easier and cures after about two hours, firmly joining the pipe to the socket. The pipes are extremely heavy, and installation can be carried out by just one person. Thanks to the socket design, the sections are held firmly in place, and installation can take place immediately after applying the lubricating cream. This means the sections remain flexible for later adjustments. The pipes can be installed quickly and easily. In fact, time savings of up to 43 percent in installation can be achieved compared with conventional methods. GAM Design Parlour and Berlin are two locations, together employing more than 450 qualified staff. Highest quality standards, and all production takes place using state-of-the-art technology.

What does sustainable actually mean? Everyone talks about it, everyone claims to be it. But what is truly sustainable is, above all, something that lasts a long time and can be readily recycled. Hot-dip galvanizing, for example, makes steel more durable. It protects against corrosion, and the material generally does not need to be maintained — it lasts for more than 50 years. That means less waste and lower costs. It can also be recycled afterwards and turned into new products. This conserves resources and helps us think even more in terms of circular processes. This way, we reduce CO2 emissions. How hot-dip galvanizing works: the steel is dipped into molten zinc at 450 degrees, and then iron and zinc bond with one another. This protects the steel from corrosion, in other words rust. In addition, the zinc coating reflects heat radiation and provides a protective effect in the event of fire. This process is natural — and the great thing is: it can simply be repeated after decades of use, and the result is then like new again. All components can be recycled 100 percent. Hot-dip galvanizing is therefore circular, and this is possible because iron and zinc form a bond. Hot-dip galvanized steel reduces CO2 emissions and helps to achieve climate policy targets. The Eiffel Tower, for example, has been repainted 19 times to date, each time using 60 tonnes of paint — if it were galvanized, this would not be necessary. Or take the re-galvanizing of crash barriers: it saves 112 tonnes of CO2 per kilometre. You could also apply a coating instead, but that has to be repeated far more often. A wind turbine contains around 19,000 hot-dip galvanized bolts. Hot-dip galvanized steel is a good climate protector and a very special material. Who is behind this? In Germany, there are more than 130 hot-dip galvanizing plants. In these predominantly medium-sized companies, more than 5,000 employees work every day for the corrosion protection and value retention of steel products. The EU as a whole even has around 600 hot-dip galvanizing facilities. The industry makes an important contribution in construction, the energy sector, mobility, agriculture and many other sectors. Hot-dip galvanized steel has become indispensable to today's society.

So what does hot-dip galvanizing mean? Hot-dip galvanizing is today the most important process for permanently protecting steel against corrosion. First, the steel parts are grouped together and pre-treated. If necessary, they are cleaned of oil and grease residues; adhering rust or scale is removed in a pickling bath. This produces metallically bright surfaces. After drying, the steel parts are dipped into a zinc bath at 450 degrees. This gives the galvanized parts a solid, resistant, abrasion-resistant and durable coating of iron-zinc alloy layers, which form through mutual diffusion. Even in hard-to-reach places such as corners, gaps and cavities — the typical weak points of other corrosion protection methods — this creates all-round, seamless protection. Quality assurance is taken very seriously at the hot-dip galvanizing plant: the entire hot-dip galvanizing process is monitored by specialist staff, so that no part leaves the facility without the appropriate inspection. Service is a matter of course for modern medium-sized galvanizing companies; whether tradesperson or industrial customer — the experts of the hot-dip galvanizing industry are happy to assist you with advice and support. Even though today almost any steel object can be hot-dip galvanized without any problems, certain factors relating to design and manufacturing should be taken into account. This is a prerequisite for optimal quality in hot-dip galvanizing. Corrosion protection through hot-dip galvanizing: durable, environmentally friendly and economical.

What does hot-dip galvanizing actually mean? In hot-dip galvanizing, zinc and steel come together as kindred partners and bond with one another. Hot-dip galvanizing is an immersion process in which finished steel components are first cleaned and then galvanized. To do this, the components pass through several pre-treatment baths, are then dried, and after drying are dipped into a liquid zinc bath at a temperature of around 450 degrees Celsius. After a reaction time of just a few minutes, the finished galvanized components can be pulled out and cooled. Hot-dip galvanizing produced by the immersion process has tangible advantages. These include long-term protection without the need for maintenance, as well as perfect all-round protection even in inaccessible places — hollow sections are even protected against corrosion on the inside. Further strengths are high abrasion and impact resistance even under heavy mechanical stress, as well as resistance to chemical influences. Thanks to the resource-efficient use of material and energy, the long-lasting corrosion protection provided by hot-dip galvanizing is particularly economical and sustainable. As a metallic coating, hot-dip galvanizing has some outstanding special features compared to other methods, such as paint coatings. In hot-dip galvanizing, a metallic coating in the form of an iron-zinc alloy is formed, which is firmly bonded to the steel surface. Undercutting corrosion, as can occur with paint coatings, is therefore not possible. The hardness of the iron-zinc alloy layers is significantly higher than the hardness of ordinary structural steel. This is the basis for the high wear and abrasion resistance of batch hot-dip galvanized coatings, which is valued during transport, installation and use. Hot-dip galvanized gratings that are walked on daily, or scaffolding components, are good examples of this high load-bearing capacity. A further advantage is the corrosion protection at workpiece edges: during the galvanizing process, a zinc coating of equal thickness — in some cases even thicker — forms at corners and workpiece edges compared with the smooth surfaces of the component. The edge recession known from coatings does not occur. Component edges and other problem zones of the structure are therefore always effectively protected 100 percent by hot-dip galvanizing. How long does a batch hot-dip galvanized coating last? That depends on the coating thickness and the respective exposure. Detailed information is provided by the so-called corrosivity categories of DIN EN ISO 14713-1. Corrosivity category C3, for example, describes urban and industrial atmospheres; the exposure here is classified as medium. According to corrosivity categories C2 and C3, more than 95 percent of the area of Germany is subject to only low or medium corrosion exposure. An average zinc coating with a thickness of 85 micrometres achieves a corrosion protection duration of at least 50 years here. Only in the few areas marked in red along the coast must a shorter protection duration be expected. If corrosion protection through hot-dip galvanizing is compared with coatings from a life-cycle assessment perspective, hot-dip galvanizing is clearly superior. A life-cycle assessment comparison by the Technical University of Berlin clearly proves this: the study shows that coating one tonne of steel consumes three times more resources than hot-dip galvanizing, produces 2.6 times more CO2, and results in a 5.5 times higher contribution to eutrophication, i.e. the over-fertilisation of bodies of water. Compared with coatings, hot-dip galvanizing saves up to 114 kg of CO2 per tonne of steel. By using hot-dip galvanizing, the corrosion exposure typical of steel structures can be brought under control without any problems; costly and environmentally harmful maintenance measures are avoided.

The LORO-X DUOSTREAM cascade drainage system with multi-storey drains and pressurised gravity flow drains several floors of a building with setback storeys via a continuous collector pipe. The drains, fitted with ventilation openings, direct the water by gravity flow into the pressure-resistant downpipe. Under excess pressure, the water is pushed horizontally across the roof terrace and through the drain via the space-saving DN 50 pipe. In the downpipe of the following storey, the principle of pressurised gravity flow is repeated. At the multi-storey drains, the water from the roof terraces flows by gravity flow into the outer DN 100 pipe. Before the transition into the underground drain, the high-performance safety overflow protects against backflow. The second stream for emergency drainage ensures drainage to the outside in the event of heavy rainfall. Emergency drainage also works on the principle of pressurised gravity flow — with the difference that all drains from the roof and from the roof terraces are fitted with a damming element, so that drainage only begins in the event of heavy rainfall. The horizontal offset across the roof terrace can be routed either above the waterproofing membrane or within the thermal insulation. For the multi-storey drains, a choice can also be made between the parapet-distance variant and the parapet-direct variant.

Here you see our new LORO-X inspection chamber made of stainless steel. It is manufactured at our LOROWERK on a laser cutting machine. The inspection chamber consists of a stainless steel lid and our stainless steel lower part. The lower part features horizontal cut-outs through which the water can flow, while preventing gravel or green roof planting from reaching the drain body. The inspection chamber is particularly well suited for the maintenance that has to be carried out on the roof twice a year. Instead of vertical cut-outs, we chose horizontal ones, so that the inspection chamber can be cut to length more easily. If we want to use the inspection chamber on a roof with bituminous waterproofing, we have already pre-formed 45-degree wedges that can be cut out with an angle grinder. If a drain is installed on the roof, for example at the parapet, we can properly rework this contour with the inspection chamber, so that the chamber fits completely flush against the parapet. The inspection chamber has further advantages: it can also be used on terraces with precast stone paving. For this, we have incorporated reinforcement areas that are variable in height; the inspection chamber can be adapted to the height of the precast stone paving using an angle grinder. A standard commercial grating or a LORO-X grating can be placed on top. Pre-formed markings for drill holes are also provided, where the angle grinder can later be applied — for example for our setback storey drains and their pipe routing, which can simply be run through here, or in the middle for the hole for our cascade drainage. This means: the two outer ones for the setback storey drainage, the middle hole for the cascade drainage. Seepage water openings and connection areas for branch channels are also provided on the sides. That is our new LORO-X inspection chamber.

Here you see our new LORO-X retention rotary valve. It is available in two variants: one as a parapet variant and one as a vertical variant for installation into the roof and pipe routing inside the building. For the retention rotary valve, we have developed an installation component that can be screwed directly onto many of our drain bodies. Underneath the hood sits a flexible stainless steel insert with five pre-formed openings of a specific opening size. By turning the retention rotary valve, the desired drainage capacity on the roof can be adjusted. Retention will establish a new benchmark for drainage technology in many cities. We have considered how the throttled water discharge from the roof can best be ensured — and this is exactly what you can achieve with our retention rotary valve. The various opening sizes and the corresponding drainage capacities are specified in the data sheet. This results in a water level on the roof. You can also start from the desired water level on the roof and then determine how many openings you need in order to drain a given number of litres from the roof. Our retention rotary valve is fixed in place after it has been set. This ensures that the product does not shift out of position over the following decades and maintains the desired water discharge.

Here at ISH in Frankfurt, we are presenting another new product: our HSÜ, the high-security overflow, in the colour grey. Until now, our HSÜ had always been in a shade of orange, so that it can be recognised as a safety device. In order to be able to better adapt to the architectural conditions on site, the HSÜ is now also available in grey. The HSÜ is important for bypassing backflow in the underground drain, so that drainage from the roof can continue to flow away. This means: you can use the HSÜ on any construction project to protect the building.

Welcome. We have brought along our new Main-Emergency Combi Flach 50. The Main-Emergency Combi is divided into a main drain and an emergency drain. Here we have an integrated weir to separate main drainage and emergency drainage. The main drainage is discharged via the DN 100 pipe, visible here on the side, and the emergency drainage is discharged via an inliner pipe in DN 50. With the Flach 50, we have an intervention depth of 50 mm into the roof. The Flach 50 has a drainage capacity of 2 litres per second for main drainage and 2.1 litres per second for emergency drainage. The emergency drainage is routed through the drain body via the DN 50 pipe and discharged into the vertical downpipe via a pipe bend. Inside the downpipe, the DN 50 pipe continues down into our standpipe. Our LORO-X standpipe has a DN 50 outlet opening in its lower section, through which the emergency drainage is then directed onto a surface that can be safely flooded without causing damage. With this, we have installed a very slim and smart system from LORO, while at the same time achieving a long service life.

Here at the ISH trade fair in Frankfurt, we are presenting our three drain body variants for the roof. Here we have a clamping collar. We also have our popular fixed-point/sliding-point flange construction, in which the waterproofing membrane is clamped and secured with screws. And brand new for the roof, we now also have a bonded flange, onto which we can apply bituminous waterproofing or liquid plastic, integrating the roof drain in this way.

At the ISH trade fair in Frankfurt, we presented our new Aktuell 86. In it, we have compiled new fire protection solutions so that planners and architects can get an idea of how our products can be installed. LORO approaches fire protection as follows: we have an open pipework system, as you can clearly see on our poster. The drain body and the pipework system all the way down are completely open. This design means that extinguishing water applied to the roof by the fire brigade can continue to drain away. This way, the building's structural stability is maintained and the building does not collapse. We offer different variants of fire protection drains: one as a siphonic drain and one as a gravity-flow drain. Also new in Aktuell 86 are our pipe penetrations and the system solutions for them, for example when routing into an underground car park. Not a new development, but still important: our LORO-X composite pipe is very simple to handle and in terms of fire protection. For slab thicknesses of 150 to 200 mm, the pipe is cast into the concrete and a 10 cm fire protection insulation is placed over the pipe. For composite pipes installed in slab thicknesses over 200 mm, insulation can be omitted; there, the pipe is simply cast into the concrete. This allows us to achieve F90 or F120 fire resistance ratings respectively. Please refer to Aktuell 86 for details on exactly which pipes this applies to.
