Spiral steel pipe needs exterior treatment to add durability:
1. The surface of the anticorrosive spiral tube is cleaned with solvents and emulsions, which can remove the organic matter on the surface of the spiral tube, but it cannot remove the rust, oxide scale, welding flux, etc., so cleaning can only be used as an auxiliary means.
2. Use a wire brush, sandpaper, and other things to polish the appearance of the anticorrosive spiral pipe, which can remove loose oxide scale, rust, welding slag, etc.
3. Chemical pickling is used for pipeline anti-corrosion, which can remove oxide scale, rust, and old coating, and can make the appearance reach a certain degree of cleanliness and roughness.
4. The high-power motor drives the spraying (throwing) blade to rotate at a high speed, so that the steel grit, steel shot, iron wire section, minerals, and other abrasives are sprayed (threw) on the surface of the anti-corrosion steel pipe under the effect of centrifugal force, which can not only be completely removed Rust, oxide, and dirt, and the anti-corrosion steel pipe can reach the required uniform roughness under the effect of strong abrasive impact and friction.
