Problems solved by technology

[0003] The rust removal of the outer wall of the metal pipe is relatively simple, and the internal rust removal is more complicated. The traditional internal rust removal is to use acid or lye to clean the inside of the metal pipe. This method will corrode the pipe and cause certain damage to the ecological environment. Impact

Description

Technical field [0001] The invention relates to a derusting device for inner walls of metal pipes with different inner diameters, and belongs to the field of mechanical processing. Background technique [0002] Metal pipes are widely used in modern life and production. Many oil and gas pipelines and water supply systems use metal pipes. Steel pipes are divided into seamless steel pipes and welded steel pipes according to their manufacturing methods. Seamless steel pipes are made of high-quality carbon steel or alloy steel, and are divided into hot-rolled and cold-rolled (drawn). Welded steel pipes are welded by butt seams or spiral seams from steel plates rolled into a tube shape. Seamless steel pipes can be used for various liquid and gas pipelines. Welded pipelines can be used for water pipelines, gas pipelines, heating pipelines, etc. [0003] The rust removal of the outer wall of the metal pipe is relatively simple, and the internal rust removal is more complicated. The tra...
