Pipe Inner Wall Shot Blasting Machine QJGN100–QJGN1500 | Jinwo, Qingdao, China

Jinwo's Pipe Inner Wall Shot Blasting Machine cleans the internal surfaces of steel pipes and pipelines. It blasts the bore of batches of pipe before welding or coating, removing oxide scale, rust, welding slag and old coatings.

Blast wheels throw steel shot at high speed against the inner wall while the pipe rotates or the blasting unit travels along its length, so the whole circumference is covered. Shot is recovered and reused, and a dust collector keeps the working area clean. Four inner wall models cover pipe from φ50 mm to φ1,500 mm.
