Compact Pipe – in mint condition

In the compact pipe procedure a HD-PE pipe, preformed in a C-shape at the factory, is inserted into a cleaned reach. During the further process, pressure and heat then provide the close-fit connection of the inliner to the inner wall of the old pipe due to the so-called memory effect.

An important advantage – besides the short installation time – is the fact that, contrary to the open cut, the procedure does not require any digging. So the inconvenience for the residents as well as for pedestrians and road traffic are kept within acceptable limits.

The compact pipe is manufactured as a standard pipe with the respective wall thickness corresponding to the standard DIN 8074. The roduct is already manufactured at the factory with the bend, which is typical for this procedure.

Therefore the HD-PE pipe is axially folded in a C-shape under defined conditions. For reasons of winding and mounting, the fold is on the side of the pipe. The consequential reduction in cross-section of up to 35% considerably facilitates the insertion into the pipeline to be rehabilitated. Depending on the nominal width, several hundreds of metres can be wound on a drum, installed and expanded.
