Steel pipe inner and outer wall shot blasting machine is a kind of shot blasting equipment for cleaning and spraying steel pipes by shot blasting. The inner and outer wall shot blasting machine produced by LongFA can rotate the surface and inner cavity of the steel pipe to remove sand, rust, welding slag, oxide and debris. The surface of the steel pipe is smooth and the paint film adhesion of the workpiece is improved, the fatigue resistance and corrosion resistance of the steel pipe are improved, and the service life is prolonged.

Steel pipe outer wall shot blasting machine: The steel pipe outer wall shot blasting machine uses the high-speed projectile thrown by the high-efficiency shot blasting machine to hit the surface of the steel pipe and cast pipe, so that it can obtain fine and bright metal primary color, improve the tensile and compressive strength of the workpiece surface, so that it has a certain roughness, to achieve anti-corrosion, pipe protection, and prolong the service life of the steel pipe.

Steel pipe inner wall shot blasting machine: steel pipe shot blasting machine mainly uses mobile blasting and shot blasting machine to throw high-speed shot flow beam to strike the oxide, rust layer and debris on the inner surface of steel and cast pipe, so that it can obtain a fine bright surface, which is conducive to improving the quality of its inner wall coating.

The working sequence of the steel pipe shot blasting machine inside and outside

Feeding support → feeding mechanism → entering the shot blasting chamber → shot blasting treatment (workpiece rotates while advancing) → shot storage → flow control → shot blasting workpiece → Vertical lifting of bucket elevator → shot slag separation →(recirculation) → Sending out the shot blasting chamber → Charging mechanism → charging support. The curved blade is used in the shot blasting device, so the inflow performance of the projectile is improved, the throwing power is increased, the reasonably compact throwing workpiece has no dead Angle, and the maintenance is more convenient.

Xinrunqi steel pipe inner and outer wall shot blasting machine has the following advantages

The centrifugal cantilever type novel and efficient multi-functional shot blasting device has the advantages of large shot blasting capacity, high efficiency, rapid blade replacement, integral replacement performance and easy maintenance;

The workpiece passes through the inlet and outlet of the shot blasting machine continuously. In order to prevent the projectile from flying outside, the machine adopts multi-layer replaceable sealing brush to realize the thorough sealing of the projectile.

The use of full curtain type BE pellet slag separator greatly improves the separation quantity, separation efficiency and blasting quality, and reduces the wear on the blasting device.

The outer wall of the same steel pipe after shot peening is treated with a round surface shot peening treatment to remove the oxide and impurities. Make up for the surface of the steel pipe micro-cracks; Eliminate the residual stress on the surface of the steel pipe, improve the strength of the substrate, and increase the surface wear resistance;

Providing active surface for coating is conducive to improving the coating quality of steel pipe, anti-corrosion, pipe protection and delaying the service life of steel pipe.
