1. The surface of the anti-corrosion spiral steel pipe is cleaned with solvent and emulsion, which 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 tools such as wire brushes and sandpaper to polish the surface of the anti-corrosion spiral steel pipe, which can remove loose oxide scale, rust, welding slag, etc.

3. The anti-corrosion of the spiral steel pipe adopts chemical pickling, which can remove the 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 spraying (throwing) blades to rotate at high speed, so that the abrasives such as steel sand, steel shot, iron wire, minerals, and other abrasives can spray (throwing) the surface of the anti-corrosion steel pipe under the action of centrifugal force, which can not only completely remove the Rust, oxides, and dirt, and anti-corrosion steel pipes can achieve the required uniform roughness under the action of abrasive impact and friction.
