Yoruba Steel Pipe Shot Blasting Machine/Steel Pipe Outer Wall Shot Blast Machines is a combination of clean-steel outer wall of cleaning machine, by blasting to clean the outer surface of the steel pipe, shot by throwing inside to clean surface, so that the surface oxide are rid off. It is used before welding or painting on its outer surface treatment of the pipes.
The QG series steel pipe inner and outer wall shot blasting machine adopts simultaneous cleaning technology for both inner and outer walls. Steel pipes are fed into the blasting chamber by a roller conveyor system. Outer wall blast wheels project abrasive from multiple angles onto the outer surface, while an inner wall blasting device extends into the pipe interior using a specially designed nozzle or blast head. completing full surface cleaning of scale, welding slag, and rust in one pass, revealing uniform metallic luster and creating an ideal rough surface profile for subsequent coating.
Simultaneous Inner and Outer Wall Cleaning
The machine cleans both inner and outer walls of steel pipes at the same time, completing full surface treatment in a single pass without separate operations.
High Cleaning Quality
Effectively removes scale, welding slag, rust, and rolling flakes from steel pipe surfaces, leaving a uniform metallic luster after treatment.
Wide Processing Range
Capable of handling various pipe specifications, from small-diameter pipelines to large-diameter oil and gas transmission lines.
Continuous Operation
The roller conveyor system supports continuous pipe flow and can be integrated with loading, painting, drying, and other processes to form an automated production line.
Automatic Abrasive Circulation
Equipped with an efficient separation system that automatically recovers and reuses intact abrasive, reducing consumable costs.
Environmentally Compliant
Integrated high-efficiency dust collection system ensures emissions meet environmental requirements.

Application of shot blasting machine
Shot blasting machines are suitable for surface cleaning and strengthening of small and medium-sized castings and forgings in industries such as casting, construction, chemical, electrical, and machine tools; Surface rust removal and painting processes for steel plates, profiles, and structural components in industries such as shipbuilding, automobiles, locomotives, bridges, and machinery; Shot blasting machines can also be used to remove burrs, diaphragms, and rust; Shot blasting machines reduce the fatigue life of parts, increase different surface stresses, and enhance the strength of components.
How to quickly determine which shot blasting machine is suitable for my industry?
The simplest basis is the size of the workpiece to be processed, and the most direct and simple way is for you to contact our professional sales team for one-on-one service and develop a plan.
Efficiency of shot blasting machine
The one-time cleaning time of the shot blasting machine is 5-30 minutes. The sales team and design team will add auxiliary tools according to the actual size and shape of the user's work piece to accommodate a larger number of work pieces.
How to deal with the malfunction of shot blasting machine?
We are equipped with professional machine operation manuals and troubleshooting manuals.
