Insulation pipe, buried pipe insulation, pipe insulation jacket black spiral steel pipes including straight seam steel pipe and seamless steel pipe. Outer layer of black polyethylene material called black jacket insulation. High pressure foaming machine with the cavity between the steel pipe and the outer protective layer is formed in a one-time injection of a rigid polyurethane foam stock solution is made, and then processing the polyethylene surface of the steel pipe, forming the outermost layer of the protective layer. Specializing in the production of polyurethane insulation pipe, buried pipe insulation, prefabricated thermal insulating tubes. 1, excellent insulation properties of polyurethane insulation, heat loss is 25% of the traditional pipe, can significantly reduce the cost of steel sleeve steel pipe insulation, energy savings. 2, waterproof excellent, excellent acid, alkali, corrosion. 3, long life polyurethane insulation pipes, up to 30-50 years. 4, vary in diameter from DN15-DN600; insulation thickness can be thick to thin from 15--500mm. 5, widely used in heating pipes, cooling pipes, chemical pipes, industrial pipes and other prices. Polyurethane insulation pipe insulation _ _ feicheng Kodak insulation shell provided by the Building Materials Co., Ltd. Weifang Kodak. Weifang Kodak Building Materials Co.
