The method comprises the following steps that a user places the two hoop-shaped mounting frames on the outer side of a pipeline, and the two hoop-shaped mounting frames are connected and fixed through connecting bolts. Through arrangement of the hoop-shaped mounting frames, the cylindrical polishing part, the elastic rope, the handle and other structures, the elastic rope can be repeatedly dragged through the handle, the sliding base is pulled to slide back and forth along the surface of the arc-shaped guide rod under the elastic cooperation of the elastic rope, and the pipeline is polished through the cylindrical polishing part; and since thegrinding track of the cylindrical grinding part is curved, the device can better adapt to the pipeline surface, and the grinding efficiency and the grinding effect are improved.
