A shot blasting machine for pipes and steel is a machine that uses a high-pressure stream of abrasive particles, such as steel shot or grit, to clean and prepare the surface of metal pipes and steel structures. The machine typically consists of a blasting chamber, a blasting wheel, and a dust collection system. The pipes or steel structures are placed in the chamber and rotated while the blasting wheel propels the abrasive particles at the surface to remove rust, scale, and other surface contaminants. This process is often used in industries such as oil and gas, construction, and shipbuilding.
