1. Cleaning

Seamless steel pipes are cleaned by cleaning. When cleaning, the surface of the steel should be cleaned with solvents and emulsions first. This method is only used as an auxiliary means of anti-corrosion and cannot remove rust from stainless steel pipes. We can also use steel brushes, iron wire balls, and other tools to remove loose oxide scales and rust on the surface before cleaning.

2. Spray rust removal

Using spray rust removal, a high-power motor drives the spray blade to rotate at high speed, so that steel sand, steel shot, wire segments, minerals, and other abrasives are sprayed on the surface of the stainless steel pipe under the action of centrifugal force. Not only can rust, oxides, and dirt be completely removed, but the steel pipe can also achieve the required uniform roughness under the intense impact and friction of the abrasive. Spray rust removal is an ideal rust removal method among pipeline anti-corrosion methods.

3. Pickling

Pickling is also one of the ways to remove rust. Generally, chemical and electrolytic methods are used for pickling treatment. Only chemical pickling is used for pipeline anti-corrosion. Although this method can achieve a certain degree of cleanliness, it can easily cause pollution to the environment, so it is not recommended.
