Scraper for cleaning burrs in welded pipe

The invention relates to the technical field of high-frequency welded pipe production, in particular to a scraper for cleaning burrs in a welded pipe. The scraper comprises a cutter bar, one end of the cutter bar is connected to an impedor tow bar, a first annular cutter and a second annular cutter are embedded on the cutter bar, and a gap is reserved between the first annular cutter and the second annular cutter. The axis of the first annular cutter inclines towards one side of the second annular cutter, the axis of the second annular cutter is parallel to the axis of the first annular cutter, cutter edges of the first annular cutter and the second annular cutter penetrate out of the surface of the cutter bar, and the distance between the cutter edge of the first annular cutter and the cutter bar is larger than that between the cutter edge of the second annular cutter and the cutter bar. A welded pipe is conveyed in the direction from the second annular cutter to the first annular cutter, and the cutter bar
