Pipe Outer Wall Shot Blasting Machine φ16–2800 mm | Jinwo, Qingdao, China

Jinwo's Pipe Outer Wall Shot Blasting Machine cleans the external surface of steel pipes in a continuous pass. It removes rust, oxide scale and welding slag from batches of pipe before welding or coating.

The pipe is carried forward on V-rollers or supporting wheels while it rotates at a constant speed through the blasting chamber. Several blast wheels throw steel shot at it from different angles, so the whole circumference is treated. The range covers seamless, welded and spiral pipes, and the shot blasting also strengthens the surface.

Key Features

• Continuous through-feed of long pipes, suited to batch production
• Pipe rotation combined with multi-angle blast wheels to treat the full outer surface evenly
• Steel shot is recycled by screw conveyors, elevators and separators
• Pulse cartridge dust collector purifies the extracted dust
• Automatic walking speed adjustment and self-rotation of the pipe
• Pit-free design with a compact footprint, needing no pits or extra drainage pipes
• No pickling waste liquid is produced

Frequently Asked Questions

• What pipe sizes can it handle? The machine is offered in models covering pipe diameters from φ16 to 2,800 mm, from QJGW100 (φ50–300 mm) up to QJGW2800 (φ1,016–2,800 mm).
• How fast does it clean pipe? Cleaning speed depends on the model: 2–10 m/min for QJGW100, down to 1–2 m/min for QJGW2800.
• Does it need a pit for installation? No, it is mostly a pit-free design, which keeps installation simple and reduces infrastructure cost.
• What should I send for a quotation? Send the pipe diameter range, wall thickness and lengths, the pipe type (seamless, welded or spiral), the surface finish required, and your target throughput in m/min or pipes per day.
