    Characteristics of hot dip plastic steel pipe

    發布時間:2020-06-20

    Hot dip plastic steel pipe is a new material with many excellent properties. The hot-dip plastic steel pipe not only overcomes the defects of traditional steel pipe, such as easy rust, corrosion and high pollution, but also avoids the defects of low strength and easy deformation. It combines the two advantages of steel pipe and plastic products. It is a product promoted and used by the government. The hot-dip plastic steel pipe has the advantages of high strength, easy connection and water impact resistance, which overcomes the disadvantages of low strength and low fire resistance of plastic pipe. The service life of hot-dip plastic steel pipe is very long, up to 50 years. The inner wall coating has strong adhesion, good impact resistance and strong cathode stripping ability. Because the coating surface of the inner wall of the pipeline is smooth, it can prevent the growth of microorganisms and scaling. Characteristics of hot dip plastic steel pipe Under the same pipe diameter and pressure, the head loss of hot-dip plastic steel pipe is 30% lower than that of metal cable pipe. The pressure bearing capacity of the hot-dip plastic steel pipe is stable, and the complete steel pipe layer is the main pressure bearing layer of the pipe body, so the pressure bearing capacity of the pipe is not affected by the change of the performance of the plastic layer. The hot-dip plastic steel pipe also has a strong high temperature resistance. The samples are kept in a 300 ℃ incubator for 1 hour, and the coating has no peeling, crack and bulging phenomenon. In recent years, the price of the hot-dip plastic steel pipe is on the rise. Because of its good insulation, softness, corrosion resistance, high temperature resistance, wear resistance and tensile resistance, hot-dip plastic steel pipe has been widely used in power transformation projects. Hot dip plastic steel pipe, also known as cable threading pipe, is a new generation of anti-corrosion pipeline product that uses new anti-corrosion materials, advanced Japanese equipment and hot dip plastic technology to achieve internal and external anti-corrosion of steel pipe, and is the upgrade of traditional anti-corrosion pipeline. It is especially suitable for the use of cable protection pipes with special requirements such as corrosion protection, compression resistance and exposure. This product is a major breakthrough in new products, technologies and processes. Compared with the traditional anticorrosive pipeline, its anticorrosive capability has been significantly improved, and its anti-aging, anticorrosive properties, mechanical strength, toughness and processability have been significantly improved. The hot-dip plastic cable pipe can be used in the working environment of - 30 ℃ ~ 120 ℃. Compared with metal pipe, plastic pipe and composite pipe, the advantages of various pipes are integrated. It not only has the strength of steel pipe, but also has the corrosion resistance, wear resistance and small fluid resistance of plastic pipe. This is a kind of green tube with health, good performance and high strength. It can be widely used in high-rise building water supply and drainage, fire sprinkler, heating and ventilation, cable internal and external anti-corrosion and other fields. Natural gas, desalination and industrial circulating water systems.
