Abstract
An apparatus for expanding a tubular member comprising a support member, an expansion device for radially expanding the tubular member movably coupled to the support member for longitudinal displacement relative to the support member, at least one pressure chamber defined by and positioned between the support member and expansion device, and one or more releasable supports coupled to the support member adapted to support the tubular member, wherein the releasable supports are positioned above the expansion device.
Claims16
An apparatus for expanding a tubular member, comprising:
- a support member comprising a fluid passage.
- an expansion device movably coupled to the support member comprising an expansion cone and a tubular piston operably coupled to the expansion cone;
- at least one pressure chamber defined by and positioned between the support member and the expansion device fluidicly coupled to the first fluid passage;
- and
- one or more releasable supports coupled to the support member adapted to support the tubular member;
- wherein the releasable supports are positioned above the expansion device.
An apparatus for radially expanding and plastically deforming an expandable tubular member, comprising:
- an expansion device for radially expanding and plastically deforming the expandable tubular member;
- a support member;
- an actuator coupled to the expansion device and the support member for displacing the expansion device in the longitudinal direction relative to the tubular member;
- and
- a locking device for the position of the expandable tubular member relative to the support member;
- wherein the locking device is positioned above the expansion device;
- and wherein the actuator comprises one of more tubular pistons.
An apparatus for radially expanding and plastically deforming an expandable tubular member, comprising:
- an expansion device for radially expanding and plastically deforming the expandable tubular member;
- a support member;
- an actuator coupled to the expansion device and the support member for displacing the expansion device in the longitudinal direction relative to the tubular member;
- and
- a locking device for preventing movement of the expandable tubular member in at least a single direction;
- wherein the locking device is positioned above the expansion device.
An apparatus for radially expanding and plastically deforming an expandable tubular member, comprising:
- an expansion device for radially expanding and plastically deforming the expandable tubular member:
- a support member;
- an actuator coupled to the expansion device and the support member for displacing the expansion device in the longitudinal direction relative to the tubular member;
- and
- a device for preventing movement of the expandable tubular member;
- wherein the device is positioned above the expansion device.
