3. Anti-corrosion spiral steel pipe anti-corrosion structure: first layer of epoxy powder (
), second layer of adhesive ()~, third layer of polyethylene.~3. The three materials are integrated and firmly combined with the steel pipe to form an excellent anti-corrosion layer. Pipe diameter range ~. The anti-corrosion pipeline has a two-layer anti-corrosion structure. The first layer is adhesive
and the second layer is polyethylene. The two materials are integrated into one, and the thickness of each layer is the same as the three layers. The production process is as follows: the bare pipe is shot blasted and rust-removed by medium-frequency heating. After rust-removal inspection, it is heated again. When it reaches a certain temperature, it is sprayed. First, powder spraying, then adhesive spraying, and finally Spray coating of polyethylene. Strictly carry out spraying and picking up leaks. This is basically the production process. 3 Anti-corrosion spiral steel pipes are widely used in pipeline engineering fields such as petroleum, chemical industry, natural gas, heat, sewage treatment, water sources, bridges, steel structures, marine water transmission piling, etc. []
