Description :
High temperature prefabricated directly buried insulation pipes have a good anti-corrosion effect due to the tight bonding of the polyurethane insulation layer to the outer skin of the steel pipe, which isolates the infiltration of air and water. At the same time, its foam pores are all closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have good anti-corrosion, insulation, and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by external air and water. As long as the water quality inside the pipeline is well treated, according to foreign data, the service life of high-temperature prefabricated buried insulation pipes can reach more than 50 years, which is 3-4 times longer than traditional trench laying and overhead laying.
