Buried hot water pipe insulation pipe insulation jacket price, polyurethane insulation pipe buried hot water pipe insulation prefabricated buried - species classification protective shell material division (1) high-density polyethylene plastic (commonly known as the jacket) protective shell. (2) glass fiber reinforced unsaturated polyester resin plastic (commonly known as FRP) protective shell. (3) the use of protective shell steam pipe insulation of other materials, such as spiral welded steel pipe, straight seam steel pipes, bellows. 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 of insulation, such as low-grade bitumen and heavy oil. It melts when heated corrosion pipe insulation, duct free expansion in the insulation layer, an insulating layer and backfill sand remains stationary. This type is mainly used for high-temperature composite disengagement pipe insulation, such as steam pipes. Heating pipe insulation, pipe insulation Yucheng, Kodak buried hot water heating pipe insulation provided by the Building Materials Co., Ltd. Weifang Kodak. Weifang Kodak Building Materials Co. (www.wfkdjc.com) strong, credible, Shandong Weifang other industry has accumulated a large number of loyal customers.
