ABSTRACT:
A tubular connection includes a pin member and box member. The pin member includes a pin thread formed on a small step and a large step and a first seal surface formed between the small step and the large step. The box member includes a box thread formed on a small step and a large step and a second seal surface formed between the small step and the large step. The pin thread and the box thread are wedge threads. The small step and the large step of both the pin member and the box member are formed on a single taper. Upon a selected make-up of the pin member with the box member, a seal is formed between at least a portion of the first seal surface and the second seal surface.
