The integrated machine for shot blasting cleaning of the inner and outer walls of steel pipes selects different shot blasting or shot blasting treatment equipment according to the diameter of the steel pipe. The shot blasting cleaning is driven by a hydraulic motor, and the shot blasting cleaning is driven by a starter motor. Our company designs large diameter inner wall shot blasting machines and large and medium-sized steel pipe shot blasting machines with a diameter of over 500mm. This equipment adopts automatic shot blasting to remove surface rust, using a high-speed shot blasting machine to break down the oxide scale, rust layer and other debris on the inner surface of the steel pipe, obtaining a fine and bright surface, improving the tensile and compressive strength of the workpiece, increasing adhesion for inner surface painting protection, and achieving the purpose of anti-corrosion, pipe protection, and prolonging the service life of the steel pipe. The surface smoothness and roughness of the cleaned workpiece meet the relevant standards and regulations. Large diameter steel pipes use inner wall shot blasting machines and steel pipe inner wall shot blasting treatment lines.

Large diameter steel pipes use inner wall shot blasting machines and steel pipe inner wall shot blasting treatment lines.

The equipment mainly consists of front and rear movable sub chambers, fixed sealed chambers, inner wall hydraulic movable shot blasting equipment, steel pipe self driving device, belt conveyor type shot conveying mechanism, bottom belt conveyor, hoist, maintenance platform, separator, dust removal system, inner wall shot blasting equipment walking mechanism, steel pipe loading and unloading mechanism, hydraulic system and electrical control system, etc.

Firstly, load the steel pipe onto the conveyor trolley through the hydraulic feeding mechanism. Three conveyor trolleys drive the steel pipe to move towards the fixed sealing chamber at the same time. After moving to the predetermined position, the trolleys stop The mobile sealing chamber and the mobile hydraulic shot blasting device move together towards the other end of the steel pipe. After completely sealing the end of the steel pipe to the detection position, the mobile sealing chamber stops. At this time, the steel pipe is in a closed state. The inner wall hydraulic shot blasting device is driven by the trolley to reach the fixed sealing chamber end. Then, the steel pipe rotation mechanism, inner throwing head, shot conveying mechanism, dust removal system, and inner throwing head moving flat car are sequentially activated. In this way, the steel pipe rotates and the inner throwing head travels, and the shot is thrown towards the side wall of the steel pipe. After completely passing through the steel pipe, the inner wall of the steel pipe is cleaned.
