##_ Anti-corrosion spiral steel pipe anti-corrosion structure: first layer of epoxy powder (>
#) second layer of adhesive (D) ~ third layer of polyethylene.~. The three materials are integrated and firmly combined with the steel pipe to form an excellent anti-corrosion layer. Pipe diameter range Φ～Φ. Two-layer anti-corrosion structure of anti-corrosion pipeline. The first layer of adhesive
# (D) and the second layer of polyethylene are two materials integrated into one. 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 to a certain temperature for spraying. First, powder spraying is performed, then adhesive is sprayed, and finally polyethylene is sprayed. Strictly carry out spraying and picking up leaks. This is basically the production process. 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 structure marine water transmission piling, etc. []
