An expandable threaded tubular connection comprising: a first tubular segment with a pin member, the pin member including interengageable thread means, a pin nose and a rib on the pin nose, the pin nose having a pin nose end, the rib being preformed on the pin nose such that the rib is not deformed during radial expansion of the threaded tubular connection; a second tubular segment with a box member, the box member including interengageable thread means suitable for threadedly engaging the pin member and a groove for receiving the rib, the box member further including a shoulder engaging the pin nose end prior to radial expansion of the threaded tubular connection; and a gap formed between the pin nose end and the shoulder during radial expansion of the threaded tubular connection, wherein the groove in the box member is sized to allow the rib to move within the groove as a result of axial movement of the pin nose during radial expansion of the threaded tubular connection.
