Slip lining

Close-fit Lining

Close-fit lining is possible because of the memory properties of PE. PE pipe will change shape when force is applied to the material either through the application of compression or tension but will return to its original shape when the external force is removed or internal pressure is applied. This property allows the PE100 or PE100-RC pipe to be temporarily deformed and pulled into the host pipe. When the new pipe has been pulled to the desired position, tension on the pipe is released or internal pressure is applied and the pipe will return to its original shape. The versatility of PE pipe has spawned the development of a wide range of innovative close-fit lining systems.

Close-Fit Lining: Die Drawing

Technique For all close-fit PE lining methods, during the reduction process the outside diameter of the PE100 or PE100-RC pipe is reduced to less than reduction that can be applied in concentric...

Close Fit Lining: Roller Reduction (Rolldown)

For all close-fit PE lining methods, during the reduction process the outside diameter of the PE100 or PE100-RC pipe is reduced to less than the minimum bore diameter of the host pipe. Once the...

Close Fit Lining: Fold and Form Lining

TECHNIQUE All PE close fit lining technologies effectively reduce the original diameter of the PE liner pipe prior to insertion, to facilitate pulling it in to the host pipe, followed by a reversion...
