2. Use a wire brush, sandpaper, and other tools to polish the surface of the anticorrosive spiral steel pipe. Can remove loose oxide scale, rust, welding slag, etc.

3. The pipeline anticorrosion adopts chemical pickling, 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) blade to rotate at a high speed, so that the steel grit, steel shot, iron wire section, minerals, and other abrasives are sprayed (threw) on the surface of the anti-corrosion steel pipe under the action of centrifugal force, which can not only completely remove it Rust, oxide, and dirt, and the anti-corrosion steel pipe can achieve the required uniform roughness under the action of the violent impact and friction of the abrasive.
