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 wire brushes, sandpaper, and other tools to polish the surface of the anti-corrosion spiral steel pipe, which can remove loose oxide scales, 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 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 (throw) the surface of the anti-corrosion spiral steel pipe under the action of centrifugal force, which can not only completely Remove rust, oxides, and dirt, and the anti-corrosion steel pipe can achieve the required uniform roughness under the action of the abrasive impact and friction.
