摘要

Tubular threaded joint (1) comprising a male component (3) with an external thread (8), a female component (2) with a corresponding internal thread (6) and means allowing the two components to be assembled to a given torque. The female component has downstream of its threaded section a female part with a bearing surface (17) and the male component has upstream of its threaded section a corresponding section with an external bearing surface (18) on its end. The two bearing surfaces are in contact pressing on each other. The female surface between the end of the thread (19) and the bearing surface and the male surface between the end of the thread (12) and the bearing surface have geometries so they form an annular zone (20- 21). At least part of the length of this zone measured along the axis of the joint (X1-X2) forms a calibrated annular space (20) in which a sealant (27) fills all or part of this space to ensure a mechanical link between the female (7) and male (13) sections.
