摘要： Threaded pipe joint comprising a male element (1) and a female element (2), threaded and provided with respective complementary sealing surfaces, which define, when screwed together, a notch (13) formed on the female element (2) of a predetermined length (X), and a space (7, 8) between the threads of predeter­mined section (S), forming reservoir to house the joint lubricant, which comes out of the volume between the threads of the female (2) and male (1) elements during the tightening of the joint.
