The tool (10) adapted for location within a pipe (11) comprises a mandrel (12), a first, inboard end (13) and a second, outboard end (14). First and second pipe engaging members (17, 18) are coupled to the mandrel (12) and each of the pipe engaging members (17, 18) is selected from one of a seal element (19, 25), a lock member and a flange member. Pistons (23, 29) are operatively associated with the pipe engaging members (17, 18) and the pistons (23, 29) are adapted to urge the pipe engaging members (17, 18) into engagement with the pipe (11). A third pipe engaging member (53), e.g. a lock member, may also be provided. The pipeline tool (10) Is modular and is configured for performing a number of different pipeline functions through selection of the pipe engaging members (17, 18), e.g. pipeline weld pressure testing, pipeline gripping and retrieval. |
