Steel Pipe External & Internal Shot Blasting Systems

Raw steel pipes from manufacturing processes carry heavy mill scale, surface oxides, and deep atmospheric rust. As a dedicated steel pipe shot blasting machine and specialized steel tube shot blasting machine solution, Steel Pipe External & Internal Shot Blasting Systems treat these metal surfaces to achieve the strict Sa 2.5 cleanliness standard required for subsequent structural welding, 3PE, or FBE anti-corrosion coating lines. Serving as a high-capacity pipe cleaning shot blasting machine, this specialized machinery runs continuous descaling operations on both exterior walls and interior tube cavities by deploying high-velocity mechanical blast wheels alongside high-pressure air blasting lances.

External surface processing relies on a heavy-duty skew roller conveyor line arranged across the workshop layout. Operating as a heavy-duty external pipe shot blasting machine and continuous external pipe blasting machine, this driving mechanism automatically rotates the steel pipe while pushing it forward along a continuous spiral path directly into the main blasting chamber. Top-mounted heavy-duty blast wheels discharge high-velocity steel shots onto the spinning workpieces, producing a uniform anchor pattern and consistent surface roughness as a high-efficiency steel pipe shot blaster across the outer wall without leaving any blast blind spots.

Internal pipe cleaning divides into distinct mechanical methods based on the specific target tube diameter. Operating as an automatic internal pipe shot blasting machine and specialized internal pipe blasting machine, small and medium pipes use automated hydraulic cantilever lances to push pressure nozzles inside the moving tube core for targeted air blasting, making it equally effective as a gas cylinder shot blasting machine and tube cleaning blasting machine. Large diameter lines deploy mechanical internal blast wheel units inside the pipe belly for high-volume throwing. Both methods utilize heavy-duty inner screw conveyors and vacuum systems to reclaim spent steel shots from the pipe interior.
