Abstract
A make-up method for a threaded joint with a pin and a box to increase the fatigue life of the joint is provided. The method includes the step of applying a torque for making up the pin in the box until first and second abutment shoulders of the pin and the box abut. The method can also include the step of applying an additional torque to the threaded joint until a magnitude of between 50% and 90% of the yield strength of the joint material in the most stressed part of the joint is reached.
