Steel pipe shot blasting machines are designed to clean and strengthen the external surfaces of steel pipes, round bars, drilling rods, and similar cylindrical components. They effectively remove rust, oxide layers, paint films, and surface contaminants while improving fatigue resistance through shot blasting.
The equipment uses a V-roller or rubber wheel conveyor system to transport the workpiece. As the steel pipe moves forward, it rotates simultaneously, ensuring uniform coverage. When passing through the shot blasting chamber, high-velocity steel shots impact the surface, achieving thorough cleaning and surface preparation.
Key components include: in-feeding roller conveyor, shot blasting chamber, blast turbines, shot recycling system, dust collection system, out-feeding roller conveyor, and electrical control system.

◆ Advantages
● High-efficiency cleaning: shot blasting machines can quickly remove rust, scale, and other impurities from steel pipe surfaces, significantly improving cleaning efficiency and making them suitable for mass production.
● Uniform treatment: the shot blasting process is uniform, ensuring thorough cleaning of the steel plate surface and achieving consistent quality standards.
● Enhanced adhesion: after shot blasting, the steel plate surface develops a suitable roughness, enhancing the adhesion of subsequent coatings, paints, or anti-corrosion materials.
● Environmentally friendly and energy-saving: the equipment adopts a high-efficiency dust fume control system, reducing dust emission produced by blasting to maxium and avoiding the use of harmful chemicals to clean metal surface, meeting environmental standards.
● Automated control: The automated system adopts PLC automatic control , reduces manual intervention, improves production efficiency, and ensures consistent cleaning results.
