Polyurethane insulation with high functionality polyether polyol and repeatedly methyl polyphenyl polyisocyanate as the main raw material, in the catalyst, blowing agents, surfactants role buried pipe insulation, foam formed by chemical reactions. Polyurethane insulation tubes have the capacity light weight, high strength, heat insulation, sound insulation, fire-retardant, cold, antiseptic, non-absorbent, quick and easy construction and other outstanding features of the steam pipe insulation, has become the construction, transport, petroleum, chemical, power, refrigeration and other industrial sectors heat insulation, water sealing, seal and other essential materials. Polyurethane insulation for central heating pipes polyurethane insulation, indoor and outdoor thermal insulation pipes, central air conditioning ducts, chemical, pharmaceutical and other industrial pipes, cold. Pipe insulation \ prefabricated buried pipe insulation structural features (1) Corrosion resistance: chemically inert material pipe insulation, excellent corrosion resistance, and according to the transmission medium to select a different pipeline corrosion. (2) mechanical strength: the strength of resistance to pressure, pressure-resistant strength and impact strength are good and may require the design and manufacture of pressure pipes and fittings. (3) temperature adaptability: Operating temperature range: -70 ° C greater than less than 250 degrees Celsius, freezing medium pipe does not crack.
