Spiral steel pipe requires surface treatment to increase durability:
1. The surface of the anti-corrosion spiral steel pipe cleaned with solvent and emulsion can remove the organic matter on the surface of the spiral steel pipe, but it cannot remove the surface rust, oxide scale, welding flux, etc., so cleaning can only be used as an auxiliary means.
2. Use wire brushes, sandpaper, etc. to polish the surface of the anti-corrosion spiral steel 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 surface reach a certain degree of cleanliness and roughness.
4. The high-power motor drives the spray (throwing) blades to rotate at a high speed, so that the abrasives such as steel sand, steel shot, iron wire, minerals, and other abrasives are sprayed (thrown) on the surface of the anti-corrosion steel pipe under the effect of centrifugal force, which can not only completely remove Rust, oxides, and dirt, and anti-corrosion steel pipes can achieve the required uniform roughness under the effect of strong abrasive impact and friction.
