Cured-In-Place Pipe (Cipp) Rehabilitation of Pressurized Potable Water Pipelines, 4 In. (100 mm) and Larger

This standard covers materials and procedures for the rehabilitation of existing water mains 4 in. (100 mm) in diameter and larger by the installation and curing of a resin impregnated textile tube that is either inverted into the main using a hydrostatic head of potable water or air pressure or pulled into the main and subsequently inflated by potable water or air. The CIPP is cured by circulating hot water, introducing controlled steam or photoinitiated reaction (light) within the resin impregnated textile tube once installed into the existing pipe. When cured the finished product will be a continuous, tight fitting cured-in-place pipe (CIPP). See more
