Abstract
A self-locking threaded connection partially in a non-locking engagement includes a first and a second tubular component provided respectively with male and female threaded zone at their respective ends. First portions of the female threaded zones with varying thread width and root cooperate together along a self-locking tightening arrangement. A locking region within the threaded connection is located in the middle of non-locking, and radially centered to the pipe body API tolerances in order to withstand high torque and seal performances.
