A thread form for a tubular connection of the type having a pin member (31) adapted to be made-up with a box member (37) to form a pipe joint as shown. The pin member has pin threads with thread crest s (33) and thread roots (35) which are adapted to be made-up with a mating box member (37) having a complimentary thread structure. The p in thread crests are formed between a stab flank (39) and a load flank (41) of the pin thread. The pin thread has a multi-faceted (69, 71, 73) complex profile stab flank for engaging a mating stab flank on the complimentary box member to provide a wedging interfit between the surfaces of the pin and box threads. The pin and box threads are also helically structured as a wedge. |
