The steel pipe inner and outer wall shot blasting cleaning machine is a device used to clean and treat the inner and outer surfaces of steel pipes. It is mainly used to remove oxides, rust, and dirt from the inner and outer surfaces of steel pipes, in order to improve the surface quality and roughness of steel pipes, enhance their corrosion resistance and adhesion

working principle

Exterior wall shot blasting machine: By spraying high-speed rotating shot blasting wheels, shot blasting particles are sprayed onto the outer surface of the steel pipe, causing the surface to be impacted and rubbed, thereby removing dirt and oxides, and forming a certain surface roughness for subsequent coating construction. ‌

Inner wall shot blasting machine: It usually uses a combination of rotating inner wall spray gun and shot blasting wheel to spray shot blasting particles onto the inner surface of the steel pipe through the inner wall spray gun, removing dirt and oxides on the inner wall and forming a certain surface roughness.

Application field

The shot blasting machine for the inner and outer walls of steel pipes is widely used in the fields of steel pipe manufacturing, petroleum, chemical industry, ships, railways, bridges, highways, etc. It is suitable for various types of steel pipes, such as seamless pipes, galvanized pipes, petroleum pipelines, chemical pipelines, etc.

operating procedure

Loading: Place the steel pipes to be processed on the loading bracket and feed them into the shot blasting chamber through the loading mechanism.

Shot blasting treatment: The steel pipe rotates while moving forward in the shot blasting chamber, and is subjected to the impact and friction of shot blasting particles to remove surface impurities.

Bullet storage and separation: Processed bullets are stored and flow controlled before being recycled for use.

Cutting: The processed steel pipe is sent out of the shot blasting room through the cutting mechanism, completing the entire processing process.
