1. Equipment Structure and Technical Configuration
The extensible arm of the machine is constructed with high-manganese steel plates for enhanced durability.
The hydraulic motor drives the blast wheel, and the machine integrates German-imported components, including a hydraulic power unit, motor, and PLC fully automatic frequency conversion control system.

2. Automatic Cleaning Process and Effects
The machine employs automated shot blasting technology to eliminate surface rust. High-speed abrasive flow, propelled by efficient blast wheels, impacts and removes oxides, rust, and contaminants from the pipe's inner surfaces. This process produces a clean, glossy finish, improves the workpiece's tensile and compressive strength, and enhances paint adhesion. These outcomes collectively prevent corrosion, protect pipelines, and extend service life.

3. The Surface Quality of Workpieces
 The cleaned surfaces achieve industry-standard smoothness and roughness levels (e.g., SA2.5–SA3).

4. Automated Loading, Unloading and Sealing System
An automatic pneumatic loading/unloading system is installed on the conveying trolley, enabling dual-side material handling.
After placing the workpiece, a mobile sealing chamber (driven by a reducer) moves toward a fixed sealing chamber, effectively sealing both ends of the pipe.

5. Abrasive Recycling and Dust Removal Process
During operation, the abrasive recovery system utilizes pneumatic conveying.
Supported by a dust collection system and negative pressure within the pipe, abrasive materials are transported to a recovery sub-chamber.
As the sub-chamber expands, the pneumatic force dissipates, and abrasives fall onto a belt conveyor for reuse.
