Medium: hot water, steam, hot oil, hot material and so on. Medium temperature: less than 350℃. Medium pressure: Hot water, steam medium not exceeding 2.5MPa. Other media are determined according to the special requirements of the medium. Laying method: Mainly used for aboveground.
Metal protective layer can be made of galvanized iron coating, stainless steel, aluminum strip and other materials, and has strong anti-corrosion and mechanical strength. Special material heat insulation is adopted between the sliding bracket and the steel pipe to effectively solve the heat bridge problem in the pipe network, and the heat loss of the pipeline is reduced to the maximum extent. Vacuum extraction technology can be used to effectively prevent the corrosion of internal and external steel pipes. The heat-insulating material has the advantages of light, durability, excellent heat preservation performance, low heat consumption and maximum utilization of heat energy. Advanced production technology, high overall strength, good stability, long product life.
