APPARATUS FOR TREATING ENDS OF LARGEDIAMETER WELDED PIPE
摘要
A large-diameter welded steel pipe having a straight seam and tab plates attached to its ends as extensions of the seam is laid along a setting line with the seam upward. An apparatus for treating the ends of such a pipe has a tab plate cutting unit and a bead removing unit. The tab plate cutting unit cuts the tab plates off with a torch. The bead removing unit removes the weld beads on the inner surface of the ends of the pipe by cutting them with a rotary cutter.
