Abstract
An oilfield tubular member 10 includes pin member 12 and box member 14 each having a tapered thread 18, 20, 70, 72. The pin thread 18 has a root 28, a crest 26, a pressure flank 34 and stab flank 36. The box thread has root 32, a crest 30, a pressure flank 84 and stab flank 86. The pin crest 26 has a stab flank pin crest radius 40 and a pressure flank pin crust radius 38 which is at least twice the radius 40. The improved oilfield connection minimizes damage to the connection during misalignment of the pin member and box member.
