Insulation pipe, buried pipe insulation, pipe insulation jacket black spiral steel pipe include polyurethane insulation pipe, straight seam steel pipe and seamless steel pipe. Outer layer of black polyethylene material called black jacket insulation. With a high-pressure foaming machine cavity between the steel pipe and the outer sheath formed a one-time injection of liquid is made of rigid polyurethane foam, and then make polyethylene pipe surface treatment polyurethane buried pipe insulation, forming the outermost layer protective layer. Steel sleeve steel pipe insulation applications: coat the outer wall of steel with high temperature resin to strengthen the level embalmed so special, the breakdown voltage greater than 3000V, so coat steel pipe coating life of more than 20 years. Selection of pipe insulation work silicate composite centrifugal cotton (or may choose other insulation materials) pipe insulation, good insulation effect. Left between the work and the jacket pipe insulation around the pipe 10-20mm gap, you can play a further role of insulation, but also extremely smooth exhaust pipes buried tidal channel, the exhaust pipe really played tidal wave timely row role, but play a role in signal tube; or be drawn into a low vacuum, can be more effective in reducing the jacket pipe wall insulation and corrosion. Buried pipe insulation, pipe insulation Kodak heating (certified), qihe pipe insulation provided by the Building Materials Co., Ltd. Weifang Kodak. 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. In Kodak leadership with the staff warmly welcome all inquiries negotiations to create a better future for Kodak.
