The emerging steel-plastic composite pressure pipe is a new type of metal-plastic composite pipe developed by Xinxing Casting Pipe Co., Ltd., with welded steel pipe as the intermediate layer and inner and outer layer of poly(ethylene) propylene plastic, using special hot melt adhesive. The integrated pipe is assembled by an extrusion molding method. This pipe is abbreviated as PSP.
The emerging steel-plastic composite pressure pipe is a new type of metal-plastic composite pipe developed by Xinxing Casting Pipe Co., Ltd., with welded steel pipe as the intermediate layer and inner and outer layer of poly(ethylene) propylene plastic, using special hot melt adhesive. The integrated pipe is assembled by an extrusion molding method. This pipe is abbreviated as PSP. The pipe overcomes the defects of easy corrosion, pollution, bulkiness, short service life and shortness of the plastic pipe, large expansion amount and easy deformation, and has the common advantages of steel pipe and plastic pipe, such as oxygen barrier property. Good, with high rigidity and high strength, the buried pipe is easy to detect. Products are classified into cold water composite pipe (L), hot water composite pipe (R), gas composite pipe (Q), special fluid composite pipe (T), and protective casing composite pipe (B). It can be widely used in the transportation of hot and cold water, drinking water, heating, gas, special fluids (including industrial wastewater, corrosive fluids, solid powder, coal mine underground water supply, drainage, pressure, spray, etc.) in urban and rural buildings. And power cables, communication cables, and composite pipes for cable protection casings. The product characteristics of the emerging steel-plastic composite pressure pipe are as follows: 1. The tensile strength of mechanical properties is 275-320 MPa, which is 7-8 times that of pure plastic pipe. 2. Thermal conductivity The thermal conductivity is 0.46~0.57W/mk, which is about 1/100 of the steel pipe, which is close to the thermal conductivity of the plastic pipe. 3, linear expansion coefficient linear expansion coefficient is 1.2 × 10-5 / ° C, is 1/10 ~ 1 / 12 of pure plastic pipe. 4, hydraulic performance steel-plastic composite pressure pipe inner wall roughness of 0.007mm, smooth inner wall, transport In the case of fluid, the resistance loss is small and there is no scaling. The structure is rigid and soft, and the pressure shock in the pipeline system can be quickly eliminated without generating water hammer noise. 5. Corrosion resistance The inner and outer polyethylene of steel-plastic composite pressure pipe is a non-polar material with very stable chemical properties. It is insoluble in any known solvent at room temperature and can withstand the corrosion of various acid, alkali and salt solutions. 6. Sanitary performance The steel-plastic composite pressure pipe is hygienic and non-toxic, conforms to the GB/T 17219 standard, and has obtained the “National Product Sanitary License for Drinking Water Health Safety†issued by the Health Department of Hebei Province. The approval number is: Wei Wei Shui (2006) No. S013, can be used for direct drinking water delivery. 7. Self-traceability can be traced by magnetic metal detectors. It is not necessary to embed tracking or protection marks to avoid excavation damage, which provides great convenience for repair and maintenance. 8, the service life of normal temperature, pressure range, can be used for 50 years. 9. The mechanical connection of the steel-plastic composite pressure pipe is mechanically connected, and the internal and external spray treatment has higher pressure bearing capacity and anti-corrosion ability than the pipe, easy installation and good sealing performance.
