Polyurethane prefabricated buried pipe insulation production details

Prefabricated buried pipe insulation production details seamless polyurethane buried pipe insulation advantages: polyurethane buried pipe insulation with high efficiency insulation, waterproof, corrosion, insulation, noise, fire, cold, corrosion, light capacity, high strength, simple and quick construction, afraid plant thorn and other outstanding features, has become the construction, transport, petroleum, chemical, electric power, refrigeration and other industrial sectors insulation, water sealing, seals and other essential materials. Buried polyurethane insulation pipe insulation for indoor and outdoor pipes, central heating pipes, central air conditioning ducts, chemical, pharmaceutical and other industrial pipes, cold engineering, pipeline engineering, transport gas and other pipeline projects. Buried polyurethane insulation since the thirties of polyurethane synthetic materials since birth, has been used as an excellent insulation material and rapid development, more and more extensive range of applications, but also because of its simple construction, energy-saving anti-corrosion effect is remarkable. Buried polyurethane insulation tubes are widely used in liquid, gas pipeline network, chemical pipe insulation works in petroleum, chemical, central heating network, central air conditioning and ventilation pipes, municipal engineering. Buried polyurethane insulation is a good insulation properties, plus safe, reliable, low construction cost of prefabricated buried pipe insulation. Buried polyurethane insulation tubes only traditional trench and overhead laying pipeline incomparable advanced technology, practical performance, but also has significant social and economic benefits, but also a powerful heating energy-saving measures. Prefabricated polyurethane buried pipe insulation technology using buried heating pipe, heating pipe technology development indicates that China has entered a new starting point. Buried prefabricated insulation than conventional types of pipe insulation has a very prominent advantages: 1, good insulation properties, heat loss is only 25% of the traditional pipe, long run can save a lot of energy, significantly reduce energy costs. 2, highly waterproof and corrosion resistance, without attached trench can be directly buried in the ground or water, construction easily and quickly, and lower total cost. 3, at low temperatures also have good corrosion resistance and impact resistance, and can be directly buried underground permafrost. 4, the service life of up to 30 - 50 years, proper installation and use can make the pipe network maintenance costs low rigid polyurethane insulation for urban heating, electric heating, water insulation, oil pipelines and other buried works widely use. It has green energy, anti-corrosion insulation, frost hardy, economic beautiful and many other advantages. Buried polyurethane insulation due polyurethane rigid foam insulation layer tightly bonded to the steel skin, cut off from air and water infiltration, can play a good anti-corrosion effect. While its foam cells are closed, water absorption is very small height polyethylene shell, fiberglass shell have good anti-corrosion, insulation and mechanical properties. Therefore, it works hard to be outside steel jacket of air and water erosion. As long as internal quality pipeline deal, according to foreign materials. Corrosion, good insulation properties, long service life. Because polyurethane prefabricated buried pipe insulation rigid polyurethane foam insulation layer tightly bonded to the steel skin, cut off from air and water infiltration, can play a good anti-corrosion effect. While its foaming holes are closed, water absorption is small. High density polyethylene shell, fiberglass shell have good anti-corrosion, insulation and mechanical properties. Therefore, it works hard to be outside steel jacket of air and water erosion. As long as internal quality pipeline deal, according to foreign materials, prefabricated polyurethane buried pipe insulation life of up to 50 years, than the traditional trench laying, overhead laying three to four times the life.
