As further improvement, described gusset is the bar shaped gusset, is connected by bolt with bracing frame or directly is welded on the bracing frame.
Compared with prior art, no matter be from scraping rear tubular member surface quality aspect or from the pipe cleaning operating aspect, the utility model is all scraped piping tool than tradition significant advantage:
1, the time of striking off surface oxide layer shortens, and has improved operating efficiency;
2, the screw thread circular boop can cause the micro-deformation of bracing frame, and the control cutter is more accurately easy in the penetraction depth on pipe fitting surface;
3, by the power set application of force, saved manpower;
4, the cutting-in amount of cutter is identical, can effectively control the pipe fitting surface and scrape the back quality.
