PU shell for central heating pipes, all kinds of refrigeration and industrial piping. Polyurethane shell there are kinds of polyurethane rigid foam polyurethane buried pipe buried pipe insulation, which uses high-functionality polyether polyol and repeatedly methyl polyphenyl polyisocyanate as the main raw material, a catalyst, a blowing agent, a surfactant next and so on, through a chemical reaction foaming. Polyurethane products with capacity of light, high-strength, heat insulation, sound insulation, fire-retardant, cold, corrosion, non-absorbent, quick and easy construction and other outstanding features, has become the construction, transport, petroleum, chemical, electric power, refrigeration and other industrial sectors insulation, waterproofing plugging, sealing and other essential materials. Polyurethane insulation buried pipe in some foreign countries has become a relatively mature and advanced technology. Over the last decade, our heating engineers by digestion polyurethane cold panels to absorb the advanced technology of polyurethane, is driving the domestic pipe laying technology to a higher level. 10 years of practical results fully proved casein polyurethane insulation buried pipe laying method compared with the traditional trench and laying of overhead, it has many advantages. Buried pipe insulation is made of steel transmission medium, high density polyethylene outer tube, and rigid polyurethane foam insulation pipe and the jacket pipe closely together. High-density polyethylene jacket pipe insulation prefabricated buried pipe buried insulating foam polyurethane foam has a very prominent advantages of polyurethane composite panels, new Albert corrosion insulation (certification), Dengzhou polyurethane from large emerging Albert County corrosion insulation Engineering Limited provided. Albert County of emerging anti-corrosion insulation Engineering Co., Ltd. (www.juanzhiwakecj.com) Hebei Langfang, insulation, insulation materials, leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. Albert corrosion insulation works in the emerging leadership with the staff warmly welcome all inquiries negotiations to create the new Albert corrosion insulation works better future.
