Abstract | A sealed threaded tubular connection resistant to successive pressure loads includes a male element including a male threading and a female element including a female threading corresponding to the male threading. At least one of the elements includes a lip extending beyond the threading to the free end of the element and the other element includes a recess for the lip. The lip includes a first zone with a peripheral surface turned towards the other element on which a first sealing surface is disposed that can be radially interference fitted against a corresponding second sealing surface disposed on the peripheral surface of the recess of the other element. The lip includes a second axially located zone between the first zone and the free end of the element that includes a first radial bearing surface turned towards the other element in contact with a corresponding second radial bearing surface disposed on the peripheral surface of the recess of the other element. The first and second zones are axially separated by a third zone with a radial stiffness lower than the first and second zones, the third zone capable of being radially deformed towards the other element by a pressure exerted thereon. |
