There Are Several Ways To Remove The Surface Of Steel Pipe 返回首页

1, cleaning

The solvent and emulsion are used to clean the steel surface made by Cold Forming Elbow Machine Price to remove oil, grease, dust, smoothing agent and similar organic matter, but it can not remove the rust, scale, flux, etc. of the steel surface, so it is only used as an auxiliary tactic in the anti-corrosion production.

2, spray (throw) shot derusting

Spraying (polishing) and removing rust is carried out by high-power motor to spray (drow) the blade to rotate at high speed, so that the abrasive such as steel grit, steel shot, wire segment and minerals can be sprayed (throwing) on the surface of the steel tube made by Cold Forming Tee Machine Wholesaler under the effect of centrifugal force. Not only can rust, oxides and dirt be completely eliminated, but the steel pipe can also reach the required average roughness under the effect of abrasive impact and friction.

3, tool rust removal

Firstly, the steel surface is polished with tools such as wire brushes to remove loose or raised scale, rust, welding slag, and the like. The rust removal of the hand tool can reach the Sa2 level, and the rust removal of the power tool can reach the Sa3 level. If the steel surface is attached with a strong iron oxide scale, the rust removal result of the tool is not ideal, and the anchor depth required for the anti-corrosion construction cannot be achieved.

4, pickling

Ordinary use of chemical and electrolytic methods for pickling disposal, pipeline anti-corrosion only chemical pickling, can remove oxide scale, rust, old coating, and sometimes can be used as sandblasting after rust removal. Chemical cleaning can make the appearance reach the inevitable cleanliness and roughness, but its anchor pattern is shallow and it is easy to cause pollution.
