Product Features

Efficient Cleaning:Rapidly removes oxide layers, rust, and contaminants from pipe inner walls, improving surface quality. Uniform Treatment:Ensures consistent inner-wall cleaning with no dead zones. Wide Adaptability:Processes pipes of various materials and diameters, suitable for multiple industrial sectors.

Eco-Friendly:Environmentally safer than chemical cleaning; no hazardous waste generated. Product Details Equipped with a parallel support mechanism for workpiece rotation and traverse movement.

For pipes <500 mm ID: Shot peening process applied. For pipes >500 mm ID: Shot blasting process applied. A dedicated inner-wall blasting wheel (hydraulic motor driven, with long shot delivery rod) enables self-adaptive positioning and adjustable blasting points.

Three-stage dust removal system: high filtration efficiency, online reverse blowing, excellent cleaning performance. Full-curtain separator: complete separation of shots, debris, and dust.

Applications

This series of machines is designed for inner-wall shot blasting of steel pipes and related components.

It removes scale, weld slag, and impurities, restoring a metallic finish and increasing surface roughness for optimal coating adhesion. Widely used in petrochemical, steel manufacturing, municipal heating, water supply and drainage, and other industries. Technical Parameters Model Cleaning Range (mm) Cleaning Speed (m/min)
