egeLiner®

Factory-folded PE pipes for close-fit-lining

Brief description

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.

Product Benefits | Product Structure

  • Minimum space requirement for the job site
  • Certified by DVGW
  • Little interference in road traffic (traffic can flow almost unobstructed)
  • Lower excavation costs due to pulling the pipe in via excavation pits or existing shafts
  • Statically sustainable piping system
  • Obtains hydraulic capacity by means of very little loss of cross-section and reduction of the wall surface roughness
