Regarding the surface treatment methods of anti-corrosion spiral steel pipes, there are currently many methods that can be operated
1. Use solvents and emulsions to clean the surface of the anti-corrosion spiral steel tube, which can remove the organic matter on the surface of the spiral steel tube, but it cannot remove the surface rust, scale, solder, 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 to remove loose scale, rust, welding slag, etc.
3. Chemical pickling is used for pipeline anticorrosion, which can remove scale, rust, and old coatings, and make the surface clean and rough to a certain extent.
4. The high-power motor drives the spraying (throwing) blades to rotate at high speed, so that steel sand, steel shots, iron wire segments, minerals, and other abrasives are sprayed (throwing) on the surface of the anti-corrosion 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 still achieve the required uniform roughness under the violent impact and friction of abrasives.
