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

The invention discloses a metal pipe inner wall rust removing device. The metal pipe inner wall rust removing device comprises a rotating disc (1); a rotating fixed hole (2) is formed in the center ofthe rotating disc (1); multiple fixed rods (3) are connected to the peripheral direction of the outer wall of the rotating disc (1); the fixed rods (3) are of hollow structures; one ends of positioning rods (4) are inserted in the fixed rods (3); the fixed rods (3) and the positioning rods (4) are slidingly connected; the other ends of the positioning rods (4) are connected with first connectingplates (10); one ends of support rods (5) are connected with second connecting plates (11), and the other ends are connected with arc pads (6); steel wire brushes (13) are arranged on the arc pads (6); fixed bolts (12) are locked by nuts (14) after penetrating through the second connecting plates (11) and the first connecting plates (10); and springs (13), positioned between the second connectingplates (11) and the first connecting plates (10), sleeve the fixed bolts (12). The metal pipe inner wall rust removing device can conveniently remove dust in metal pipes in a mechanical mode.
Description
technical field [0001] The invention relates to a rust removing device for the inner wall of a metal pipe, which 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 can be divided into hot-rolled and cold-rolled (drawn). Welded steel pipes are welded by butt seams or spiral seams from rolled steel plates. Seamless steel pipes can be used in various liquid and gas pipelines, etc. Welded pipes can be used for water pipes, gas pipes, heating pipes, 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 traditional internal rust removal is to use ...
