Large-diameter anti-corrosion spiral pipe refers to a steel pipe that has been processed by anti-corrosion technology to effectively prevent or slow down corrosion caused by chemical or electrochemical reactions during transportation and use. The main anti-corrosion process is. Anti-corrosion (mainly suitable for drinking water pipes)./Anti-corrosion first layer of epoxy powder, second layer of adhesive, and third layer of polyethylene. Epoxy coal tar pitch anti-corrosion (prepared from epoxy resin, coal tar pitch, anti-rust pigments, additives, modified amines. The product dries quickly, has good adhesion, good flexibility, two-component packaging, and is easy to construct. It is acid-resistant , alkali resistance, salt resistance, water resistance, oil resistance, etc.). .Epoxy powder anti-corrosion (the electrostatic spraying process is used to coat epoxy powder on the surface of the steel pipe to form a film in one go. The coating has the advantages of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance) . The main implementation standards are epoxy powder anti-corrosion implementation/-"Technical Standard for Fused Epoxy Powder Outer Coating for Steel Pipes"/Anti-corrosion Implementation/-(Test) "Technical Standard for Polyethylene Outer Coating for Buried Steel Pipes".
