Abstract:
A pipe tool, useful for cutting, removing a weld, and/or truing a pipe, comprises a housing; a drive interface; a gripper selectively insertable into an inner annulus of a pipe and movable independently of the housing, the gripper comprising a selectively expandable grip; a radially disposed cutter adapted to selectively engage a predetermined portion of an outer surface of the pipe, the cutter movable independently of the housing and the gripper; and a motor operatively in communication with the drive interface. In embodiments, a pipe is cut by maneuvering the pipe tool proximate an open end of a pipe, moving the gripper into the pipe; extending the grip to engage an interior wall of the pipe and secure the pipe tool from movement relative to the pipe; advancing the exposed face to a predetermined position relative to the pipe; axially advancing the cutter to engage an outer wall of the pipe; and rotating the housing until the cutters perform the desired cutting operation on the pipe.
