Abstract
A tool assembly configured for location on a section of a pipe is operable to both isolate a section of the pipe and perform an intervention into the pipe while maintaining pressure integrity. The tool assembly includes a clamp, a cutting tool and an isolation tool. In use, the clamp sealingly secures the tool assembly to the pipe, the cutting tool performs an intervention operation on the pipe, and the isolation tool isolates the section of pipe in order that repair or replacement of equipment can be effected.
Claims19
A tool assembly for use in the isolation of, and intervention into, a pipe, the tool assembly comprising:
- a clamp configured for location about a pipe;
- a lock arrangement for securing the tool assembly to the pipe, wherein the lock arrangement is configured for location within the clamp such that the lock arrangement is interposed between an inner surface of the clamp and an outer surface of the pipe on location of the clamp about the pipe, wherein the lock arrangement comprises a taper lock comprising a first lock member and a second lock member, and a tapered inner surface of the first lock member is configured to co-operate with a tapered outer surface of the second lock member to urge the second lock member into engagement with the pipe to secure the tool assembly to the pipe, wherein at least one of:
- the first lock member comprises a plurality of separate elements or segments, and the first lock member elements or segments are coupled together by a first lock member coupling, wherein the plurality of separate elements or segments are a slot and pin restraint, or
- the second lock member comprises a plurality of lock elements or segments, and second lock member is coupled to the clamp by a second lock member coupling, wherein the plurality of separate elements or segments are a radial screw;
- a seal arrangement for sealing between the tool assembly and the pipe, wherein the seal arrangement is configured for location within the clamp such that the seal arrangement is interposed between the inner surface of the clamp and the outer surface of the pipe on location of the clamp about the pipe;
- an activation arrangement configured to activate the lock arrangement and actuate the seal arrangement, wherein the activation arrangement comprises an activation member, and wherein the seal arrangement is located between the lock arrangement and the activation member;
- a cutting tool operatively associated with the clamp, the cutting tool configured to sever the pipe into a first pipe section and a second pipe section;
- and
- an isolation tool operatively associated with the clamp, the isolation tool comprising a seal element configured for location between the first pipe section and the second pipe section to isolate a section of the pipe.
