Plastic-coated steel pipe manufacturing process and others: it can be used under harsh conditions and has a long-term anti-corrosion life. Heavy-duty anti-corrosion coatings can generally be used for 10 or 15 years in chemical atmospheres and marine environments, even in acid and alkali, salt, and solvent medium, and under certain temperature conditions, they can also be used for more than 5 years. The thick film is an important symbol of heavy-duty anti-corrosion coatings.
It is a steel-plastic composite that uses steel pipe as the base material, plastic powder as the coating material, a layer of plastic layer on the inner surface, and a layer of plastic layer or other anti-corrosion layers on the surface. commodity. According to the different materials of the inner coating, there are two types, one is polyethylene-coated steel pipe. The other is an epoxy-coated steel pipe. The gas plastic-coated steel pipe is a three-layer PE plastic-coated steel pipe, the layer is a heavy-duty anti-corrosion modified epoxy resin, and the outermost layer is sprayed. Strong corrosion resistance and high-temperature resistance, good chemical stability and solubility of petroleum products, the use temperature range is 40°C-90°C for long-term use. Gas-plastic-coated steel pipe has strong coating adhesion and maintains good physical properties, especially excellent impact resistance and strong resistance to cathodic stripping. The coating surface is smooth and beautiful. Prevent the reproduction of microorganisms.
Through the plastic-coated anti-corrosion of steel pipes or galvanized pipes, the problems of corrosion and scaling that occur during the burial of general steel pipes and water delivery are solved. Put an end to the phenomenon of pipe blockage and spray blockage, and improve the service life of PE pipes. Its service life is more than 50 years. The powder coating of the plastic-coated steel pipe is added with a flame retardant and modified epoxy resin powder. The coating has excellent temperature resistance and will not calm down or soften during long-term use.
