Product description

The shot blasting machine of the inner and outer wall of the steel pipe is a kind of derusting machine which is combined to clean the inner and outer walls of the steel pipe. The outer surface of the steel pipe is cleaned by shot blasting, and the surface of the surface is removed by Throwing Shot Peening on the inner surface. The machine mainly uses high speed pellets thrown out by high power and powerful projectile to throw out the surface and inner cavity of the rotating workpiece in the chamber, and remove other sand, rust layer, slag, oxide skin and its sundries, so that it can get fine gloss surface. The adhesion of the paint film to the steel surface is improved, the fatigue strength and corrosion resistance of the steel are improved, the internal quality of the steel is improved and the service life of the steel is prolonged.


The working order of the steel pipe throwing rust removing machine:

1, the cleaning sequence of the workpiece to the feeding frame, the feeding mechanism, the throwing pellet room, the Throwing Shot treatment (rotating the edge of the workpiece at the edge of the workpiece). Separation of pellet slag - (recirculating)
