Abstract
An apparatus for cutting pipe includes a central cutting station formed by a ring member carried on a support at the ground so as to be independent of the pipe with an in-feed conveyor apparatus on one side and an out-feed conveyor apparatus for on the other side. The ring member rotates around the axis of the pipe and carries in the rotation a camera, a cutting device and a welding head. The support assembly provides movement of the ring member transversely to and longitudinally of the axis of the pipe. The cutting head can be tilted to form a bevel on the pipe end. The apparatus is controlled by a control system for controlling rotation of the ring member and longitudinal movement of the support assembly so as to cut the pipe in selected directions for welding of the ends or for cutting pipe pups.
Claims15
Apparatus for cutting pipe comprising:
- a cutting station;
- an in-feed conveyor apparatus for feeding the pipe to be cut into the cutting station;
- an out-feed conveyor apparatus for feeding the pipe after cutting from the cutting station;
- the cutting station comprising a ring member for surrounding an axis of the pipe arranged outwardly around an exterior wall of the pipe;
- the ring member being mounted for rotation around the axis of the pipe;
- a cutting device mounted on the ring member for rotation with the ring member so as to provide cutting of the pipe;
- a support assembly for supporting the ring member;
- the support assembly being carried on a support surface independently of the pipe so as to be movable relative to the pipe;
- the support assembly being arranged to provide movement of the ring member transversely to the axis of the pipe to locate the axis relative to the ring member;
- the support assembly being arranged to provide movement of the ring member longitudinally of the axis of the pipe;
- and a control system for simultaneously controlling rotation of the ring member and longitudinal movement of the support assembly so as to cut the pipe in selected directions which include directions different from a radial plane of the axis of the pipe.
