Insulation of life up to 50 years, than the traditional trench laying, row strike laid high life 3--4 times. Much lower than other pipe insulation material used in the past prefabricated polyurethane insulation, thermal insulation effect progress 4-9 times. Further its low water absorption polyurethane insulation pipes, about 0.2kg / m2. The reason is because of low water absorption rate of closed-cell polyurethane foam about 92%. Pipe insulation, polyurethane insulation pipes, prefabricated polyurethane insulation does not require masonry massive trench, simply bury people underground pipe insulation pipe insulation, thus greatly reducing the project area, reducing the earth excavation is about 50%, reduce civil 90% of the amount of masonry and concrete. Meanwhile, heat pipe trenching parallel processing and on-site, just live joints, can shorten the duration of about 50%. Yellow jacket pipe insulation, pipe insulation manufacturer Kodak (certified), Tai'an insulation provided by the Building Materials Co., Ltd. Weifang Kodak. Weifang Kodak Building Material Co., Ltd. (www.wfkdjc.com) Shandong Weifang, other leaders, over the years, the company implement 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 subjects.
