Since the insulation tightly bonded polyurethane rigid foam insulation layer steel jacket pipe insulation, cut off from the air and water to penetrate steel jacket steam pipe insulation, can play a good anti-corrosion effect. While its foaming holes are closed, water absorption is small. High density polyethylene shell, fiberglass shell have good anti-corrosion, insulation and mechanical properties. Therefore, it works hard to be outside steel jacket of air and water erosion. As long as internal quality pipeline deal, according to foreign materials, the service life of high temperature prefabricated buried pipe insulation up to 50 years, than the traditional trench laying, overhead laying high life 3--4 times. In addition to Chinese and foreign production of buried pipe insulation polyurethane buried pipe insulation, has a leakage alarm line, once the pipeline leakage occurs somewhere, conduction through the alarm line, pipe insulation seepage can show on a dedicated instrumentation, the exact location and extent of the size of the leak leaking to notify the subject of infiltration staff quickly handle leaking pipe, ensure the safe operation of heating pipe network. At the end of the domestic production of pipe insulation provided leakage alarm line, to be fill this gap. Pipe insulation, steel jacket pipe insulation, pipe insulation manufacturer Kodak (certified merchants) are provided by Kodak Building Material Co., Ltd. Weifang. Weifang Kodak Building Material Co., Ltd. (www.wfkdjc.com) to provide "pipe insulation, black jacket pipe insulation, polyurethane insulation pipe, buried pipe insulation, heating pipes," such as business, the company has "Kodak pipe insulation, Kodak black jacket pipe insulation, polyurethane insulation Kodak, Kodak buried pipe "and other brands. Focus on other industries, have higher visibility in Weifang. Welcomes inquiries, contact: Mr. Chen.
