Pipe FIPP thermoplastic forming repair

Pipe FIPP thermoplastic forming repairWith the rapid construction of underground pipelines in China, there is an increasing demand for pipeline inspection and non excavation repair engineering technology, as more and more underground pipelines are approaching their service life. The non excavation pipeline repair process is to heat and soften the prefabricated lining pipe on the equipment, then pull it into the interior of the pipeline, and then heat and pressure the interior of the lining pipe to restore its original diameter or expand it, making it tightly fit with the original pipeline. Then, normal temperature gas or cold air is introduced to cool it and form a new layer of lining pipe. In situ FIPP thermoplastic forming repair of pipelines, also known as Cured In Place Pipe (CIPP) repair technology for drainage pipelines, involves lining a layer of liquid thermosetting resin on the inner wall of an existing old pipeline and curing it to form a thin layer of pipe that fits tightly with the old pipeline. The pipeline cross-section is not lost, but the flow performance is greatly improved. This method is flexible, safe, and fast, which not only reduces the interference of various constraining factors, alleviates traffic pressure, but also greatly improves construction efficiency.

Pipe FIPP thermoplastic forming repairfeature

1. The construction is convenient and fast, with minimal impact on the surrounding environment, and the overall integrity of the pipeline is good after the repair of the lining pipe.

2. Can repair pipelines with misalignment (within 5cm) and curved pipelines less than 45 °, as well as repair variable diameter pipelines and irregularly shaped pipelines.

3. After repair, the inner lining pipe has minimal diameter reduction compared to the original pipeline, smooth inner walls, and increased pipeline flow capacity.

4. After repair, the inner lining tube can be heated and removed at any time.
