What is the purpose of plastic coated steel pipe?

發(fā)布時(shí)間:2020-06-19

As we know, the plastic coated steel pipe is a kind of steel plastic composite steel pipe. It takes the steel pipe as the matrix, and integrates the plastic anti-corrosion coating (lower pipe) or plastic anti-corrosion coating (lower pipe) on the inner surface of the steel pipe through the process of spraying, rolling, soaking and absorption. Plastic coated steel pipe has excellent corrosion resistance and small friction resistance. Because of its excellent performance, the coated steel pipe can be applied in all aspects, among which the epoxy resin coated steel pipe is suitable for the transportation of water supply and drainage, sea water, warm water, oil, gas and other media, while the PVC coated steel pipe is suitable for the transportation of drainage, sea water, oil, natural gas and other media, which greatly facilitates our life. The national standard for coating thickness of plastic coated steel pipe is: PE (modified polyethylene) coating thickness is 400 um ≤ 1000 um, EP (epoxy resin) coating thickness is 100 um ~ 400 um. In addition, the coated steel pipe also has excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce electrical corrosion. The utility model has the advantages of low water absorption, high mechanical strength and small friction coefficient, which can achieve the purpose of long-term use. It can also effectively prevent plant root damage and soil environmental stress. Easy to connect and maintain. It is commonly used in underground and humid environments, and can be used in high and very low temperature environments. Its anti-interference ability is strong. If plastic coated steel pipe is used as cable sleeve, it can effectively shield external signal interference. The pressure strength of plastic coated steel pipe is good, and the maximum pressure can reach 6 MPa. There is no burr, and the insulation performance is stable. As the protective pipe of metal wire, there is no leakage at all through wire or cable, i.e. through steel wire pipe. Fire steel pipe - plastic coated steel pipe inside and outside Plastic coated steel pipe also plays an irreplaceable role in the fire pipeline. Plastic coated steel pipe is used for fire steel pipe. Plastic coated steel pipe is a kind of thermosetting powder coating. The outer wall has high adhesion, impact resistance, corrosion resistance and weather resistance. The inner wall has high adhesion, corrosion resistance and food grade hygiene thermoplastic powder coating. Composite steel pipe is a high cost-effective product of traditional steel pipe and galvanized steel pipe, which is made of sand blasting chemical double pretreatment, preheating, inner coating, outer coating, curing and post-treatment. With the continuous development of the economy, the inside and outside plastic coated steel pipes for fire protection are also constantly refreshing the recognition of the outside world. Due to the long service life, the country also takes environmental protection as the top priority for future development. The inside and outside plastic coated steel pipes for fire protection are favored by the market, but the products in the market are uneven, so when selecting and purchasing the inside and outside plastic coated steel pipes, you must polish your eyes and choose a high-quality one Qualified products.
