摘要： A tubular goods connection for releasably coupling tubular members includes: a coupling having a first internal wedge dove-tail thread formed within a longitudinal bore of the coupling and a second internal dove-tail wedge thread; a first tubular member having a first mating external vanishing dove-tail wedge thread extending from a first proximal pin end face; and a second tubular member substantially identical to the first tubular member; wherein when the first and second tubular members are made-up into the coupling using a predetermined recommended optimum torque, a distance D between the first pin end face and the second pin end face is in the range of 0 to 10 millimeters and when the distance D is equal to 0 there is contact between the first pin end face and a second pin end face of the second tubular good but there is no axial interference.
