Thermal Insulation Steel pipeline Definition:Â Thermal Insulation Steel pipeline is tightly adhered to the outer skin of the Plastic Coated Steel Pipe because of the rigid polyurethane foam insulation layer, which can isolate the infiltration of air and water, and can play a good anti-corrosive effect. At the same time, its foam pores are closed and its water absorption is very small. HDPE shell and FRP shell have good anticorrosion, insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is hard to be eroded by the outside air and water. As long as the internal water quality of the pipeline is well treated, according to foreign data, the service life of the high-temperature prefabricated directly buried insulation pipe manufacturer can reach more than 50 years, which is 3-4 times longer than that of the traditional trench laying and overhead laying. Application:Â tongmao Heat preservation pipe is suitable for conveying all kinds of media in the range of - 50 - 150 . It is widely used in the transportation of central heating, cooling and hot oil, as well as the heat preservation and cold preservation projects in warm room, cold storage, coal mine, petroleum, chemical industry and other industries.Please contact me via
