Lining With Continuous Pipe

Definition - What does Lining With Continuous Pipe mean?

Lining with continuous pipe is a method of pipe lining where the pipe to be inserted is prepared before installation to match the length of the host pipe. It is a form of sliplining that involves a continuous pipe that, unlike close-fit pipes, does not require reshaping prior to insertion. Sliplining is used in trenchless rehabilitation to extend the life of older pipes that have become defective over time.

Trenchlesspedia explains Lining With Continuous Pipe

One method for rehabilitation of a defective pipe is to use a lining with continuous pipe. It is made possible because of its flexible pipe material, such as high-density polyethylene (HDPE) or fusible polyvinyl chloride. These pipes are often delivered in bundles and assembled on site.

Continuous pipe lining is generally more suitable for narrower pipes, while large-diameter pipes are often lined with discrete pipes. Lining with continuous pipe is installed into the host pipe at an insertion point and pulled through until it reaches the exit pit.
