Profiled Flexible Pipes - A Comeback for Sliplining in Pipe Renovation

 

Rehabilitation

Plastic Pipes Conference Association # 1992 Eindhoven

Lund

The design requirements of an axially flexible and cross-sectionally stiff pipe for use in pipe renovation are discussed. This application also puts stringent demands on the joint configuration. Ways to solve these problems are proposed.
One renovation system, marketed as Fiexoren, based on such a pipe is described in some detail. A typical renovation project using this system is outlined.

Sliplining, being the oldest and over time most widely used of the pipe renovation methods, has been losing market share for the last decade. Increasingly, more sophisticated methods, making use of cured-in-place sockets, pipes cross-sectionally deformed prior to insertion, or spirally wound pipes, are being used. This is so despite the fact that such methods require expensive equipment and make use of complicated installation procedures.
