Shot blasting is a process powered by a high-power motor that drives the blast nozzle at high speed, using abrasives like steel shot, steel balls, fine iron wire segments, and minerals to abrade the surface of seamless steel pipes under the force of centripetal acceleration. Not only does it effectively remove rust, metal oxides, and debris, but it also achieves the required surface roughness by the impact and friction of the abrasive materials on the seamless steel pipes.

After shot blasting, not only does it expand the physical adsorption effect on the pipeline surface, but also enhances the mechanical adhesion between the anti-corrosion layer and the pipeline surface.
