Polyurethane insulation pipe buried by the transmission medium steel, polyurethane rigid foam insulation and high-density Polyethylene jacket tube closely together, buried pipe insulation is mainly used for urban central heating pipe network, oil pipelines, the alpine region water pipelines and producing industrial pipeline project. Buried pipe insulation with a simple and efficient insulation, water preservation and construction, the advantage is not afraid plant thorn, construction without laying black leather trench jacket tube child, to burial, and traditional process of heat loss in the 0.6-1.2 m permafrost ratio can be reduced by 40%, the life of buried pipe insulation corrosion than other insulation materials increased by 3-5 times, life can reach 30-50 years of high density polyethylene jacket heat pipe manufacturers of polyurethane outer jacket pipe insulation, foam prefabricated buried pipe insulation foam in the results of 10 years of practice has fully proved casein polyurethane insulation buried pipe laying method compared with the traditional trench and laying overhead, has many advantages. Buried pipe insulation is made of steel transmission medium high-density polyethylene plastic jacket, high-density polyethylene outer tube, and rigid polyurethane foam insulation layer between the steel and the outer tube closely together. Pipe insulation is a high quality polyurethane insulation buried pipe insulation Buried Buried polyurethane insulation tubes, more than 100 years of history and production applications. High-density polyethylene plastic jacket, Kodak high-density polyethylene plastic protective shell, Zaozhuang jacket tube provided by Kodak Building Materials Co., Weifang. Weifang Kodak Building Materials Co. (www.wfkdjc.com) Shandong Weifang, the other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
