Pipeline Renewal Technologies is introducing an innovative method for monitoring cure temperature of cured-in-place-pipe (CIPP) liner installations.

By NASSCO member Ed Kampbell, PE, Jason Consultants

There are four key elements to having a really good Cured-in-Place Pipe (CIPP) installation:
1. Proper saturation of the tube;
2. Proper inflation of the resin saturated tube in the host pipe;
