What are KMR[SPM] – Short Pipe Modules

The new pipe installed using the shortlining or burstlining method consists of short pipe modules made of thick-walled PVC pipes with a solid wall. The total length of the modules is 58 centimeters, and they can be successively connected inside typical DN1000 or DN1200 manholes.

KMR [SPM] pipe modules are available in diameters from 160 mm to 630 mm. They are manufactured from PVC pipes with standard diameters and a circumferential stiffness of at least 8 kN/m2 (heavy type). The socket and spigot end of the connection fit into the thickness of the pipe wall and thus the external and internal diameter of the assembled pipe is constant over its entire length. The tightness of the module connections is ensured by rubber seals. The appropriate design of the spigot and socket of the module ensures the tightness of the connection even with angular deflections of up to 3°. Standard diameters of pipe modules allow them to be connected with typical sewer socket fittings (T-pieces, elbow pipes, reductions, prefabricated trays, etc.).

Due to the connection system of pipe modules they can only be used for trenchless renovation, replacement or construction of non-pressure pipelines: sanitary, rainwater or combined sewer system as well as technological channels.
