Polyurethane foam with a variety of materials strong adhesive, so as a buried pipe insulation is almost no need to consider the problem with the adhesion of the coating. Adapt to the temperature polyurethane insulation layer is + 120 ℃ -196 ℃, short-term (ten hours) up to + 190 ℃. If you need long-term temperature of 190 degrees, we can use high-temperature molding material according to user needs. Status Quo: Hebei Xing Song Polyurethane Co., Ltd. is the largest professional manufacturers of polyurethane foam insulation, with 20 years of experience in development and production. Polyurethane foam insulation pipe insulation tubes are widely used in liquid, gas pipeline network, chemical piping insulation works in petroleum, chemical, central heating network, central air conditioning and ventilation pipes, municipal engineering. High temperature prefabricated buried pipe insulation prefabricated buried pipe insulation is a good insulation properties, plus safe, reliable, low cost of the project. Effective solution to the urban central heating in 130 ℃ -600 ℃ high temperature heat transport prefabricated buried pipe insulation insulation, sliding lubrication and pipe end waterproof problem. High temperature prefabricated buried pipe insulation not only has the traditional laying of the pipeline trench and overhead incomparable advanced technology, practical performance, but also has significant social and economic benefits, but also effective measures heat energy. High temperature prefabricated buried pipe insulation technology using buried heating pipe, heating pipe technology development indicates that China has entered a new starting point. Buried steel sleeve steel pipe insulation pipe work from the inside and outside to protect steel and intermediate insulating layer. Work blasted steel two coats rust. By high temperature insulation mat, lightweight porous calcium silicate insulation tile and polyurethane foam components. After sandblasting steel jacket for six wound fiberglass and resin coating. Features: 1, waterproof 2, high temperature high pressure for medium temperature 350 ℃, pressure 2.5Mpa 3, low heat consumption, heat insulation is better than any conventional mode 4, corrosion resistance, high coating strength, not damage 5, long life, up to 30-50 years of life
