The outer‑wall shot blasting machine for steel tubes is specially developed for steel tube external surface cleaning. Steel tubes are continuously conveyed through the blasting chamber by roller tables. Multiple blast wheels are arranged circumferentially to deliver 360‑degree full‑coverage cleaning for tube outer walls, efficiently removing rust, scale, welding slag and surface contaminants. Core wear‑resistant parts including distributor, control cage and blades own high wear‑resistance and long service life. Abrasives are recycled in closed‑loop. Equipped with high‑efficiency dust removal system, it effectively suppresses dust leakage and keeps workshop clean. Suitable for steel tubes of various diameters and lengths, it features adjustable conveying speed and high automation with uniform blasting without missed areas. Stable operation, quick replacement of wearing parts and low failure rate. Widely applied in pipe processing, steel‑structure, pressure‑vessel and oil‑gas‑equipment industries, it provides efficient and stable pre‑treatment solutions for outer‑wall rust removal of steel tubes.
