The inner and outer wall of the steel pipe shot blasting machine is a shot blasting equipment of the inner wall and the outer wall of the steel pipe. The outer wall shot blasting treatment, the inner wall according to the diameter of the pipe to take shot blasting or shot blasting cleaning, to remove the sand, rust, oxide, dirt on the surface of the workpiece, so that the surface of the workpiece shows the metal color, eliminates the internal stress of the workpiece, improves the fatigue resistance of the workpiece, and achieves the purpose of improving the surface and internal quality of the workpiece. And finally improve the corrosion resistance of mechanical products and metal profiles and improve the fatigue resistance of steel, extend its service life; Optimize the process state of the steel surface to achieve the purpose of complete cleaning.
