Full name of polyurethane foaming thermal insulation spiral steel pipe: high-density polyethylene plastic sheath polyurethane foam prefabricated directly buried thermal insulation pipe, which is composed of working steel pipe, polyurethane thermal insulation layer, polyethylene plastic sheath pipe conveying medium, and is combined outward through equipment in turn.

High density polyethylene plastic protected polyurethane foam prefabricated directly buried insulation pipe is very popular because of its excellent performance, convenient construction and long service life (30-50 years). Its structure is composed of three parts: external protection layer, insulation layer and anti leakage layer. The external protection layer is made of polyethylene jacket pipe or glass fiber reinforced plastic or other materials. There are three types of laying methods: direct burial, overhead, and trench laying.
