Abstract
A threaded pipe connection includes a box member and a pin member. The box member has multiple internal, generally dovetail-shaped threads, each with stab flanks, load flanks, roots, and crests. The pin member also has multiple external, generally dovetail-shaped threads, each with stab flanks, load flanks, roots, and crests. The internal threads of the box member each increase in width in one direction, while the external threads of the pin member increase in width in the other direction so that the complementary flanks of the respective threads move into engagement upon make-up of the connection.
