Patent ID: 7478842

Claim:
A coupled threaded connection comprising: a first tubular section comprising a first external thread and a first pin nose, the first pin nose comprising a first pin nose surface, a first pin seal surface, and a first pin shoulder surface, wherein the first pin seal surface is disposed between the first pin nose surface and the first pin shoulder surface; a second tubular section comprising a second external thread and a second pin nose, the second pin nose comprising a second pin nose surface, a second pin seal surface, and a second pin shoulder surface, wherein the second pin seal surface corresponds to the first pin seal surface; and a coupling comprising a first internal thread adapted to connect to the first external thread, a second internal thread adapted to connect to the second external thread, and an inner seal support, wherein upon a selected make-up of the first tubular section and the second tubular section with the coupling, the first pin nose is in an overlapping axial position with the second pin nose such that contact occurs between the first pin nose surface and the second pin shoulder surface and contact occurs between the first pin seal surface and the second pin seal surface, contact between the first pin nose surface and the second pin shoulder surface acting as a positive-stop torque shoulder and contact between the first pin seal surface and the second pin seal surface forming a seal therebetween, wherein upon the selected make-up, the inner seal support is in an overlapping axial position with the first pin nose and the second pin nose and a selected diametrical gap exists between the inner seal support and the first pin nose and the second pin nose, wherein the first pin nose surface and the second pin shoulder surface are in a hooking arrangement, and wherein upon the selected make-up, contact occurs between the second pin nose surface and the first pin shoulder surface.
