Abstract
A connector for connecting the abutted end portions of two pipes includes a ring having a pair of radially inwardly extending surfaces directed towards each other and each for engagement with a radially outwardly extending surface on a respective pipe end. The surfaces on the pipe ends are directed away from the respective pipe ends and the connector includes operating means for causing radial expansion of the ring to disengage the ring from one of the pipes, the ring remaining engaged with the other pipe. To this end the corresponding surfaces on the ring and the other pipe have a greater radial extent than the surfaces on the ring and the one pipe, so that the former surfaces remain engaged for all conditions of use of the connector. The connector is particularly suited for connecting the pipe sections of a pipe string for use in the drilling and/or completion of offshore oil or gas wells, particularly where the pipe string is to be subject to high axial load for example in pile driving.
