Cured In Place Pipe

A cure-in-place pipe (CIPP) is a trenchless rehabilitation process to repair existing pipelines. The CIPP is a jointless, seamless, pipe-within-a-pipe with the capability to rehabilitate pipes. A resin saturated lining tube is installed in a pipeline by winching or inversion and once in place the resin is usually heated to induce a chemical catalyst or hardener set off the curing process. The curing process is usually by hot water, steam or UV light for hot cured methods. CIPP Lining techniques can be used to renovate most gravity pipelines and culverts and pressure pipelines used for utility services such as water and sewage.
There is very little digging involved in this process, thus making it a more environmental friendly method than traditional methods. This method also helps the flow capacity as it is much smoother than old clay and concrete pipes, it also can be made for specific applications such as corrosion, chemical resistance and pressure required.
