The high-speed Shots (steel shots, steel sand, etc.) are casted to the outer surface of the steel pipe by shot blasters. The Shots hit the surface of the steel pipe with a strong impact force to make the rust, scale and other impurities fall off to achieve the purpose of rust removal.

This method has high rust removal efficiency and can quickly remove the stubborn rust layer on the surface of the steel pipe, and at the same time of rust removal, the impact of the shots can also produce a certain crushing stress on the surface of the steel pipe, improve the power of resist fatigue strength and corrosion resistance of the steel pipe.
Technical process
The steel pipes that have passed the appearance inspection enter the external shot blasting line. On the conveyor the steel pipes connected end to end, rotating and going spirally forward, and enter the external shot blasting room for rust removal operations.
The steel pipes connected end to end on the conveyor and pass through the shot blasting machine. The shot blaster drives the steel grits to hit the outer surface of the steel pipe, so that the oxide scale on the outside of the steel pipe is knocked off by the steel grits, and a clean outer surface is obtained to achieve the Sa2.5 level of cleanliness specified in the coating standard.
During the shot blasting process, a certain amount of steel wire segments are added to the grits, and the required anchor pattern depth is formed under the impact of the steel wire segments to enhance the adhesion of the coating.
