LORO-X Concentric transition pipes

DIN 1986-100 6.1.7: Transitions to larger nominal diameters must be made with transition fittings or other suitable connections (e.g. transition seals). In collecting branch pipes, eccentric transition fittings (see further below on this page) should be installed flush at the crown."

DIN 1986-100 6.1.8: "Reductions of pipe nominal diameters in the direction of flow are, with the exception of rainwater pipes operated full bore by design, not permitted." 

The extended spigot end enables the installation of LORO-X anchor clips, when the pipe system is to be subjected to higher pressures. 

Concentric transition pipes with recessed socket and compact design enable a space-saving widening of the nominal diameter.

According to EN 12056-3 7.6.1, when widening in nearly horizontally laid pipes, the pipe crown must remain flush. The widening should therefore be eccentric "downward".
