How to improve the durability of spiral steel pipes

1. Use solvents and emulsions to clean the surface of the anti-corrosion spiral tube. This can remove organic matter on the surface of the spiral tube, but it cannot remove rust, oxide scale, flux, etc. on the surface, 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 pipe to remove loose scales, rust, welding slag, etc.

3. Chemical pickling is used for pipeline anti-corrosion, which can remove scale, rust, and old coatings, and make the surface reach a certain level of cleanliness and roughness.

4. The high-power motor drives the spray (throwing) blades to rotate at high speed, so that abrasives such as steel sand, steel shots, iron wire segments, and minerals 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 also achieve the required uniform roughness under the strong impact and friction of abrasives.
