Abstract
A pipe end-sealing tool comprises a body. A seal is mounted on the body and is adapted to apply a sealing pressure to an inner wall of a pipe end to be sealed. A lock is also mounted on the body and is adapted to engage an outer wall of the pipe end. Thus, a load applied to the pipe wall by the lock opposes the sealing pressure.
Claims (24)
1. A pipe end sealing tool comprising:
a body;
a seal mounted on the body and adapted to apply a sealing pressure to an inner wall of a pipe end to be sealed; and a lock mounted on the body and adapted to engage an outer wall of the pipe end, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
a body;
a seal mounted on the body and adapted to apply a sealing pressure to an inner wall of a pipe end to be sealed; and a lock mounted on the body and adapted to engage an outer wall of the pipe end, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
2. The tool of claim 1, wherein the seal comprises a compression seal.
3. The tool of claim 2, wherein the tool is configured such that radial movement of a sealing surface of the seal and a sealing pressure is produced by axial compression of the seal.
4. The tool of claim 1, 2 or 3, wherein the seal comprises an elastomeric seal element.
5. The tool of any one of claims 1 to 4, wherein an annular seal element is provided on a core between opposing compression faces, the faces being relatively movable to compress the element and induce radial expansion of the element.
6. The tool of any one of claims 1 to 5, wherein the seal is adapted to be self-energised.
7. The tool of claim 6, wherein once a minimum pressure differential is achieved across the seal, the tool is configured such that internal pipe pressure tends to maintain the seal in the energised configuration.
8. The tool of any one of claims 1 to 7, wherein the lock comprises a lock member adapted to be selectively urged into engagement with the wall of the pipe.
9. The tool of claim 8, wherein the lock comprises a taper lock.
10. The tool of claim 8 or 9, wherein the lock member comprises an inclined surface and is operatively associated with a relatively movable cooperating member with a corresponding inclined surface.
11. The tool of claim 8, 9 or 10, wherein the lock member includes a surface configuration for gripping the pipe wall surface.
12. The tool of any one of claims 1 to 11, wherein the lock is adapted to be configured such that an ejection load on the tool serves to increase the grip of the lock on the pipe wall surface.
13. The tool of claim 12, wherein the ejection load path through the tool is arranged to bypass a lock actuation system.
14. The tool of any one of claims 1 to 13, wherein the seal and lock are actuated separately.
15. The tool of any one of claims 1 to 13, wherein the seal and lock are adapted to be actuated by a common actuation arrangement.
16. The tool of any one of claims 1 to 15, wherein at least one of the seal and lock is fluid actuated.
17. The tool of any one of claims 1 to 16, wherein the lock is adapted to be actuated prior to actuating the seal.
18. The tool of any one of claims 1 to 17, including a fill/vent port.
19. The tool of claim 18, wherein the port extends through a tool core.
20. The tool of claim 18 or 19, wherein the port is configured to provide a high point vent.
21. The tool of any one of claims 1 to 20, wherein the tool comprises a dual seal, whereby a volume between two seals can be pressurised and monitored to allow the integrity of the seal to be verified before pressurising the pipe.
22. A method of sealing an end of a pipe, the method comprising:
providing a tool comprising a seal and a lock, both mounted on a tool body;
locating the seal within a pipe end and the lock externally of the pipe end;
engaging an outer wall surface of the pipe end with the lock; and applying a sealing pressure to an inner wall surface of the pipe end with the seal, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
providing a tool comprising a seal and a lock, both mounted on a tool body;
locating the seal within a pipe end and the lock externally of the pipe end;
engaging an outer wall surface of the pipe end with the lock; and applying a sealing pressure to an inner wall surface of the pipe end with the seal, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
23. A pipe end sealing tool comprising:
a body;
a seal mounted on the body and adapted to apply a sealing pressure to a wall of a pipe end to be sealed; and a lock mounted on the body and adapted to engage a wall of the pipe end, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
a body;
a seal mounted on the body and adapted to apply a sealing pressure to a wall of a pipe end to be sealed; and a lock mounted on the body and adapted to engage a wall of the pipe end, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
24. A method of sealing an end of a pipe, the method comprising:
providing a tool comprising a seal and a lock, both mounted on a tool body;
locating the tool on the end of a pipe;
engaging a wall surface of the pipe end with the lock; and applying a sealing pressure to a wall surface of the pipe end with the seal, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
providing a tool comprising a seal and a lock, both mounted on a tool body;
locating the tool on the end of a pipe;
engaging a wall surface of the pipe end with the lock; and applying a sealing pressure to a wall surface of the pipe end with the seal, whereby load applied to the pipe wall by the lock opposes the sealing pressure.
