Polyurethane insulation pipe used in heating pipeline famous manufacturer
Polyurethane insulation pipe used in heating pipeline manufacturer Cangzhou Guang Sheng steel pipe manufacture limited company is famous in North China specialized in the production and sale of steel pipe and pipe fittings for large enterprises. Company main products has prefabricated straight buried insulation pipe, steam insulation pipe, polyurethane insulation pipe; cement mortar anti-corrosion; polyurethane sent bubble straight buried pipe; steel sets steel steam insulation pipe; FRP resin anti-corrosion; this company is located in "pipeline equipment production base" of Hebei province Yanshan County Industrial Park. East Pro huanghua port, North by Beijing, and Jin, 205 State Road, and 104 State Road, and Beijing Shanghai Railway cross transit, domestic transport is convenience; also from Xingang only 200 km, for export business provides has more convenience of conditions. Abundant resources, superior location, making rapid development of our factory set fitting research, development, production in one of the provincial science and technology enterprises, the large pipe factory.
Heat transmission in the medium and small oil or heating pipes, to the soil to reduce the pipe heat pipe external layer with thermal insulation composite. Common insulation is rigid polyurethane foam, application temperature of-185~120℃. This material is loose, to increase its strength, outside of the insulation layer and apply a layer of high density polyethylene layer, formed composite structures to prevent infiltration of groundwater into insulation. Polyurethane foam using high- voltage equipment to blast the pipe outer surface rust and protective tube corona treatment process, improve the adhesion properties of pipe insulation. Insulation materials for rigid polyurethane foam density 60kg/M3 to 80kg/M3, fully filled gaps between the pipe and casing, and has some good bonding strength, steel tube, jacket pipe and insulation layers form a solid overall. Polyurethane foam has good mechanical and thermal insulation properties, typically temperature 120 ℃, through modification of or in combination with other materials can withstand temperature of 180 ° c.
