The external pipe shot blasting machine can removal the oxide scale, rust and other sundries from the pipe outer and inner to have a good effect of derusting, reach the national standard of SA2-SA3 in SR/TQ414-98.

It can improve the tensile and compresive resistance of the pipe surface and can also possess the reliable depth of abrasion pattern, so as to get strong adhesion of the coating on the pipe with a satisfying result of anticorrosion and therrmal insulation.

Meanwhile, the derusting speed can be adjusted as 1-6m/min according to different types.

Features and Benefits
