CIPP

CIPP trenchless pipeline repair technology is a trenchless pipeline repair method, all called "Cured-In-Place Pipe".

CIPP technology is an in-situ curing method that is mainly used to repair damaged or aged underground pipelines without the need for large-scale excavation work. The implementation of this technology involves using a non-woven lined pipe or fiberglass outer coated with a polymer coating, which is turned into a sewer or sewage pipe by water gravity or compressed air pressure, or dragged into the pipe. Once the liner is fully installed in the main pipeline, the resin is chemically reacted by heating (such as heating with water, steam or ultraviolet UV heating) to start curing, which takes about 4-8 hours. After the lining is cured, it will form a new continuous pipeline with full structural strength in the original pipeline, thereby improving the performance and life of the pipeline.

The characteristics of CIPP technology include non-destructive, fast and efficient, the ability to remove sediment and debris from pipes, and the ability to apply to many types of pipes, such as sewage pipes, pressure pipes, and chemical pipes. These features make CIPP technology an efficient and cost-effective solution for pipeline rehabilitation, especially when the location of the pipeline to be repaired is difficult to excavate.
