The steel pipe is widely applied to the field of pipelines due to the characteristics of stable chemical performance, cold resistance, heat resistance, pressure resistance, corrosion resistance, fire resistance and the like. In the process of manufacturing the steel pipe, because of manufacturing processes such as hot rolling, cold rolling and the like, the inner surface of the steel pipe is inevitably provided with unevenly distributed burrs, so that the flatness of the inner surface of the steel pipe is poor. Therefore, the burrs on the surface of the steel pipe need to be treated. Polishing refers to a process of reducing the roughness of a workpiece surface by mechanical, chemical, or electrochemical actions to obtain a bright, flat surface. The method is to carry out modification processing on the surface of a workpiece by using a polishing tool and abrasive particles or other polishing media. Therefore, the polishing technology can be applied to the inner wall of the steel pipe and used for removing burrs on the inner wall of the steel pipe, so that the surface of the inner wall of the steel pipe is flat and bright.
