CIPP is called curing in place pipeline, that is, curing in place.

According to the different construction technology, it is generally divided into overturning method and pulling method. Fiber reinforced composite hose is used as carrier, impregnated with synthetic resin, and then lined into the cleaned pipeline, and repaired by pulling or overturning. Due to the flexibility of the composite hose

Therefore, regardless of the shape of the pipeline to be repaired, under the pressure, the inner lining pipe can be closely attached to the inner wall of the pipeline to be repaired, and after curing, the pipeline to be repaired forms a composite pipeline with strong integrity.
