How to improve the durability of spiral steel pipe

Views: 0    

Spiral steel pipe requires surface treatment to increase durability:

1. Use solvents and emulsions to clean the surface of the anti-corrosion spiral tube, which can remove the organic matter on the surface of the spiral tube, but it cannot remove the surface rust, 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 tube 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 degree of cleanliness and roughness.

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 effect of centrifugal force, which can not only completely remove Rust, oxides, and dirt, and the anti-corrosion steel pipe can still reach the required uniform roughness under the action of strong abrasive impact and friction.
