New chemical material pipelines such as: steam pipelines, oxygen pipelines, nitrogen pipelines, hydrogen pipelines, toluene xylene pipelines, ethylene pipelines, etc., can remove rust, welding slag, welding rods, soil, bricks, gloves, weeds, wrenches, etc. in the pipeline through cleaning and rust removal, so as to improve the purity of materials during material production, and cause damage to pipeline equipment and instrumentation by removing the residues and dust in the pipeline, so as to achieve safe and efficient production, and reduce the rust and corrosion of the inner wall of the pipeline through pipeline drying and passivation. It can prolong the service life of the pipeline.
