发明名称 Thread form with multifaceted flanks
摘要 A thread form for a tubular connection of the type having a pin member adapted to be made-up with a box member to form a pipe joint as shown. The pin member has pin threads with thread crests and thread roots which are adapted to be made-up with a mating box member having a complimentary thread structure. The pin thread crests are formed between a stab flank and a load flank of the pin thread.
