PU REHABILITATION HOSE
This lay flat hose is innovated for prolonging the life of pipelines. It is mainly applied as a function inhabitation for corroded pipelines, without digging leaking sections out and replacing them with new pipes. It is a lay flat hose of high strength, with PE, PVC, or TPU as cover, and TPU, HDPE, PA, or PVDF as inner lining, its reinforcement layer is made of polyester or aramid fiber.
