According to the structure in the form of insulation and high temperature heat medium pipe division prefabricated buried pipe insulation (1) disengaging insulation pipe: steel pipe coating and insulation between the low melting point of the coating layer, such as low-grade bitumen and heavy oil. It melts when heated pipe insulation, duct free expansion prefabricated Buried pipe insulation manufacturers, insulation and backfill sand remain stationary in the insulation. This type is mainly used for high-temperature composite disengagement pipe insulation, such as steam pipes. Heating water pipe construction polyurethane insulation manufacturers offer prefabricated buried pipe insulation, hot and cold water waste buried insulating tubes offer effectively reduce the project cost. According to an estimate of polyurethane wall insulation, polyurethane insulation dual control heating pipes, under normal circumstances can be reduced to 25% of project cost (using fiberglass to make a protective layer) and 10% (high-density polyethylene as a protective layer) around . Low heat loss and save energy. Buried prefabricated pipe insulation manufacturers | Kodak black jacket insulation pipe price (certified) | pipe insulation provided by the Building Materials Co., Ltd.
