Surface Treatment Methods for Anti-corrosion Spiral Steel Pipes

1. Cleaning the surface of the anti-corrosion spiral steel pipe using solvents or emulsions can remove organic matter, but it cannot remove rust, scale, welding flux, etc., so cleaning can only be used as an auxiliary method.

2. Grinding the surface of the anti-corrosion spiral steel pipe using tools such as wire brushes and sandpaper can remove loose scale, rust, welding slag, etc.

3. Chemical pickling for spiral steel pipe anti-corrosion can remove scale, rust, and old coatings, and achieve a certain level of cleanliness and roughness on the surface of the spiral steel pipe.

4. Using a high-power motor to drive the high-speed rotation of the blasting (polishing) blades, steel grit, steel shot, iron wire segments, minerals, etc., abrasives are used to blast (polish) the surface of the anti-corrosion steel pipe under centrifugal force. This not only thoroughly removes rust, oxides, and dirt, but also achieves the required uniform roughness under the intense impact and friction of the abrasives.
