ABSTRACT:
A subsea telescoping joint having an outer tubular member, and an inner tubular member, an internal serrated locking and metal-to-metal sealing surface within said outer tubular member, an external serrated locking and metal-to-metal sealing surface on the exterior of said inner tubular member, means sealing between the tubular members to provide a pair of fluid chambers between the members, means for supplying pressure fluid to said chambers, the locking and sealing surfaces having a slight interference fit which allows relative movement of the members with the presence of fluid pressure in said chambers and on relieving of such fluid pressure from said chambers the surfaces move into locking and metal-to-metal sealing engagement with each other. In one form of the invention the sealing means are at the same diameter so that there is no pressure force developed tending to extend or retract the joint and in another form the sealing means are at different diameters so that a force is developed responsive to the fluid pressure tending to extend the telescoping joint.
