Patent ID: 7621034

Claim:
A method of producing a tubular threaded joint including a male tubular element having a conical male thread, a female tubular element having a conical female thread that interacts by screwing with the male thread, and a deformable sealing ring interposed between the male and female elements so to oppose communication of fluid between an outside of the tubular joint and a zone of interaction of the male and female threads, the sealing ring being in sealed contact with the male thread, and the female element having an annular housing to receive the sealing ring, disposed axially between its free end and the female thread and limited axially by a first shoulder facing the free end, the sealing ring bearing axially against the first shoulder and being in sealed contact with a peripheral surface of the housing, the method comprising: placing a deformable sealing ring around the male thread; thereafter engaging the free end of the male element; and screwing the male thread into the female thread, the sealing ring, during the screwing, being pushed along the male element by the first shoulder, rotated by the female element and compressed radially between the male thread, into which it is pressed, and the peripheral surface of the housing.
