Development of buried pipe insulation is very slow, one of the few plants to produce only a small amount of thermal insulation pipe buried underground, but the Chinese insulation industry after 30 years of efforts of high-density polyethylene pipe insulation, especially after nearly 10 years of rapid development, many products from scratch, from single to diversity, quality from low to high density polyurethane insulation, more and more common. Polyurethane material is currently the most commonly used insulation material. Rigid polyurethane insulation has many excellent properties, widely used in the United States and Europe in the field of thermal insulation. Insulation materials in Europe and other developed countries, about 49 percent of the polyurethane material, while the proportion in China is still less than 20%. So black jacket polyurethane insulation, polyurethane insulation materials buried in China there is still much room for development. Heating pipe insulation prefabricated buried three layers from the inside to the outside structure: steel sleeve steel pipe insulation applications: steel sleeve steel buried steam pipe insulation is widely used in liquid, gas pipeline network, chemical piping insulation works in petroleum, chemical, centralized heating network, central air conditioning and ventilation pipes, municipal engineering. Steel Buried steel steam pipe insulation sleeve insulation, sliding lubrication and water problems exposed pipe ends. 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.
