Development of buried pipe insulation is very slow polyethylene outer sheath black jacket foam pipe insulation, one of the few plants can only produce a small amount of insulation buried underground pipe insulation pipe insulation, but the Chinese insulation industry after 30 years of efforts, especially after nearly 10 years of rapid development, many products from scratch, from single to diversity, from low to high quality, more and more common. Polyurethane material is currently the most commonly used insulation material. Rigid polyurethane has many excellent properties of polyethylene foam insulation black jacket pipe, 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%. Therefore heating foam pipe insulation, polyurethane insulation buried in China there is still much room for development. High temperature corrosion polyurethane insulation heating pipe, buried GB polyurethane foam pipe insulation from save energy, reduce costs, shorten the construction period, to protect the environment in many ways, not only has the traditional trench and overhead laying pipeline incomparable technical and practical performance, but also has significant social and economic benefits, but a high-quality buried heating pipeline project must also have reasonable design, reliable quality and a well-insulated pipeline construction three conditions. Since the buried heating technology in China started late, more than three conditions still need to continue to improve.
