    Abstract: A tubular connection includes a first joint of casing having an integral box end with an internal female wedge threaded zone having wedge threads disposed on a portion of the integral box end, and a second joint of casing having an integral pin end with an external male wedge threaded zone having wedge threads disposed on a portion of the integral pin end. The external male wedge threads engage with the internal female wedge threads. The second joint of casing has an internal diameter D1, and also includes an internal annular recess with an internal diameter D2. D2 is greater than D1, and the annular recess is disposed longitudinally along an inner surface of the second joint of casing. The annular recess is positioned radially adjacent to a portion of the external male threads disposed on a lower portion of the pin end.

    Abstract: A threaded pipe connection is disclosed for connecting two joints of pipe having externally threaded pin members (10, 12), one pin member (10) having external right-hand threads (14) and the other pin member (12) having left-hand threads (16). An internally threaded coupling (18) having right and left-hand threads (20, 22) that mates with the threads (14, 16) on the pin members (10, 12). An internal pressure seal ring (23) is positioned to provide a seal between the ends of the pin members (10, 12). A plurality of mating lugs (24) and grooves (26) on the ends of the pin members (10, 12) hold the pins from relative rotation when the connection is being made up. A metal-to-metal seal located between each pin member (10, 12) and the coupling (18) adjacent each end of the coupling (18) isolates the threads of the connection from the ambient environment thus sealing off the pipe annulus from external pressure due to hydrostatic head. Indicia such as engaging surfaces (24a, 26a) or aligned scribe lines on the pin members (10, 12) ensure that the sealing surfaces (28, 29, 30, 31) on the coupling (18) and the pin members (10, 12) that form the external seals are positioned to properly engage and form seals when the connection is made up.
