Trenchless pipe renewal with a new, statically stable PE pipe system

Category:

Close-fit-lining with PE folded pipes

The egeliner is a polyethylene pipe that is specially thermomechanically deformed respectively folded during manufacture. The maximum length of pipe reeled on coils is determined by the diameter of the pipe. The reduction in the diameter means that the new pipe can easily be inserted into the old pipe using a winch. The recovery of the pipe is achieved by heating it with steam, which activates the memory effect of the PE pipe, returning it to its original, round shape. The new pipe will then lay close-fit to the old pipe, as an independent, statically stable pipe.
