Spray (throwing) rust removal is achieved by using a high-power motor to drive the spray (throwing) blades to rotate at high speed, causing abrasives such as steel sand, steel shot, iron wire segment, and minerals to spray (throwing) the surface of the steel pipe under centrifugal force. This not only completely eliminates rust, oxides, and dirt, but also achieves the required average roughness of the steel pipe under the fierce impact and friction of the abrasive.

After spraying (throwing) rust removal, it can not only expand the physical adsorption effect on the surface of the pipe, but also strengthen the mechanical adhesion effect between the anti-corrosion layer and the surface of the pipe. Therefore, spraying (throwing) rust removal is an ideal rust removal method for pipeline anti-corrosion. Generally speaking, shot blasting (sand) rust removal is mainly used for the internal and external surface treatment of pipes, while shot blasting (sand) rust removal is mainly used for the surface treatment of pipes.
