Spiral steel pipes protect the important materials in media transportation. Spiral steel pipes are the outer wall anti-corrosion of steel oil, gas, water, and heating pipelines. To what extent can the durability of spiral steel pipes be improved? The durability of spiral steel pipes has become an important signal for urban development!


Surface treatment of spiral steel pipe is conducive to improving its service life.
1. Use wire brushes, sandpaper, and other tools to polish the surface of the anti-corrosion spiral pipe to remove loose scale, rust, welding slag, etc.
2. Use solvents and emulsions to clean the surface of the anti-corrosion spiral tube. This can remove the organic matter on the surface of the spiral tube, but it cannot remove the surface rust, oxide scale, flux, etc., so cleaning can only be used as an auxiliary means.
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 spraying (throwing) blades to rotate at high speed, so that abrasives such as steel sand, steel shots, iron wire segments, and minerals are sprayed (throwing) on the surface of the anti-corrosion steel pipe under the action of centripetal 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 action of violent impact and friction of abrasives.
