The CIPP technology is widely applied and is suitable for trenchless repair of gravity flow pipelines, water supply pipelines, fuel gas pipelines and other pressure pipelines. The composite material is prepared by impregnating a non-woven fabric lining pipe or glass fiber with a polymer coating (PU or PE) coated on the outer layer, and then turning the non-woven fabric lining pipe or the glass fiber into a sewer or a sewage pipe by water gravity or compressed air pressure, or dragging the non-woven fabric lining pipe or the glass fiber hose into a pipeline. Once the liner is fully installed in the main pipe, the resin is chemically reacted by heating with water, or by introducing steam, or by ultraviolet UV heating, and curing is initiated for about 4-8 hours. After the lining is solidified, a new continuous pipeline with full structural strength is formed in the original pipeline.
