The shot blasting machine for the inner and outer walls of the steel pipe is a cleaning machine that combines the inner and outer walls of the steel pipe. Clear by shot blasting

Manage the outer surface of the steel pipe. Clean interior surfaces by shot peening. Remove the sticky sand, rust layer, welding slag on the inner and outer walls,

Oxide and its debris. for a fine smooth finish.

Improve the tensile and compressive strength of the workpiece. Paint protection for the inner and outer walls, increase adhesion, achieve anti-corrosion,

The purpose of protecting the pipe and prolonging the service life of the steel pipe.

This series can be customized for Φ160-250mm steel bar material and shot blasting cleaning of steel pipe products between Φ300 and Φ3000.

(2) Shot blasting machine for inner and outer walls of tower
  
     The inner and outer walls of the fan tower are shot blasted, and the inner and outer walls of large pipes can also be cleaned. Through shot blasting, the oxide scale and old paint on the surface of pipes and steel tanks can be quickly removed to obtain a certain surface roughness. The surface can be coated with a protective layer. Improve the adhesion of paint film. And improve the anti-fatigue strength and anti-corrosion ability of the workpiece, improve the inherent quality of the workpiece and prolong the service life.
     Use shot peening technology to clean the inner wall of the inner cylinder, mainly you have compressed air as power. The projectile is accelerated to generate a certain kinetic energy, and the pipe fitting and the inner wall of the cylinder are sprayed. When the pipe fitting is positioned in the spray gun chamber, the spray gun will automatically extend into the inner cavity of the pipe fitting, and the spray gun will move up and down in the cavity to complete the all-round spray cleaning of the inner wall of the pipe fitting.
     The shot blasting machine for the outer wall of the tower tube is a new type of shot blasting cleaning equipment researched by our company. It is suitable for derusting the surface of the outer wall of the wind power tower, and adopts a high-efficiency shot blasting machine, which is a closed shot blasting with good contact between shot blasting and the tower. The machine adopts the way of tower rotation and shot blasting machine moving along the axis of the tower to achieve cleaning and rust removal, which can quickly and cleanly complete the shot blasting and rust removal of the outer wall of the wind power tower (steel pipe).
     The inner wall shot blasting trolley also walks on the beam while the shot blasting is carried out on the beam, and the walking is controlled by frequency conversion. The surface of the finished tower tube presents a ring-shaped spiral silver-white strip with a certain width and width, and the traveling speed of the trolley is matched with the rotation speed of the tower tube. The adjacent silver-white strips overlap each other this time. Can make the surface of the tower without any omission. The way of sanding the steel pipe can be changed to: in the process of sanding. The taxi trolley does not move at the same time. After one circle is completed, it moves to a working position and then another circle until the inner wall of the steel pipe is finished.
