Spiral steel pipe maintenance medium transportation is one of the important materials. Spiral steel pipe is the anti-corrosion of the outer wall of high-grade steel oil, gas, water, and heating pipelines, and the durability of the spiral steel pipe is improved. The durability of the spiral steel pipe has become an important signal for urban development! The surface treatment of the spiral steel pipe is conducive to improving its service life.
1. Use tools such as wire brushes and sandpaper to grind the surface of the anti-corrosion spiral pipe, which can remove loose oxide scale, rust, welding slag, etc.
2. Use solvent and emulsion to clean the surface of the anti-corrosion spiral tube, which can remove the inorganic substances on the surface of the spiral tube, but it cannot remove the surface rust, oxide skin, welding flux, etc., so cleaning can only be used as an auxiliary wrist.
3. Chemical pickling is used for pipeline anti-corrosion, which can remove oxide scale, rust, and old coating, and can 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 the abrasives such as steel sand, steel shot, iron wire, minerals, and other abrasives can be sprayed (thrown) 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 reach the required average roughness under the action of abrasive impact and friction.
After understanding the quality improvement method of spiral steel pipes, it is certain that certain methods will be found in the manufacture of spiral steel pipes in the future or when selecting high-quality spiral steel pipes.
