Steel pipe outer wall shot blasting derusting machine

The large-scale steel pipe outer wall shot blasting cleaning machine is a new type of steel pipe outer wall shot blasting cleaning equipment developed by our company on the basis of introducing the technology of the United States and Italy and adopting the modern computer simulation technology. It can remove the oxide skin on the surface of the steel pipe, fully meet the cleaning requirements of the steel pipe outer wall before coating, and meet the cleaning needs of large and medium-sized engineering steel pipe outer wall.

It has the following advantages:

(1) Adopting the popular small pit structure, the construction cost and time of pit foundation are saved, and the problem of shot sand corrosion and caking in hoist caused by pit water storage is solved.

(2) The fifth generation cantilever centrifugal shot blaster with large shot quantity and high shot speed is adopted, which significantly improves the cleaning efficiency and achieves satisfactory cleaning quality. It is a patented product.

(3) The equipment is redesigned according to the technology at home and abroad Steel pipe shot blasting machine (steel pipe shot blasting derusting machine) is driven by a high-power motor to rotate the blade of the shot blasting machine at high speed, so that the steel sand, steel shot, steel wire cutting shot and other abrasives are sprayed (thrown) on the surface of the steel pipe under the action of centrifugal force. It can not only remove rust, oxides and dirt, but also achieve the required rough surface under the effect of abrasive impact and friction force Roughness.
