egeLiner® is a polyethylene pipe for limited spaces at the jobsite. It is deformed and folded by means of a special thermomechanical treatment during manufacture. Long lengths, even with larger dimensions, can be wound on to drums due to the reduced cross-section. For the redeformation process, the egeLiner® is warmed up with steam after installation. The memory effect activated in this way causes the PE pipe to regain its original round form. The new pipe now lies as a static independent pipe, close-fit against the old pipe.
