ABSTRACT:
A device for deburring the inner longitudinal welding seam of longitudinally moving, seam welded conduits. The device includes an elongated frame with a trailing head on which there is mounted a cutting ring positioned to cut or deburr such seam. The cutting ring dimensions and position effects enhanced deburring. Superior spring structure and hydraulic means effect improved positioning of the device within the conduit. Also an improved dovetail connection between the head and the frame avoids breakdowns.
