摘要： The invention concerns a male threaded joint (1) tipped with a male lip (18)having a male seating face (13) and a male stop (14) transverse surface (16) proximate to the male seating face; and a female threaded element (21) comprising, for co-operation with the corresponding means of the male threaded element a female seating face (23) and a female stop transverse surface provided on a female shoulder and proximate to the female seating face. The annular female shoulder zone (24) which is subjected to axial compression forces resulting from the pressure of the male (16) and female (26) stop surfaces have an inner peripheral surface (27) whereof the diameter (IDB) is at least locally proximate to said female stop surface (26) smaller than the diameter (IDP) of the inner peripheral surface (17) of the male lip (18), the ratio R of said two diameters (IDB/IDP) being less than 1 but not less than 0.9.

摘要： A female component for a tubular hydrocarbon working string subjected to dynamic bending strength includes a tapered female threading cooperating with a male threading to form a rigid mutual connection of tubular elements, a free end and female sealing surface disposed between the free end and the female threading, the female sealing surface to contact in a made up condition with a male sealing surface to form a metal-metal seal, and an annular groove provided between the free end and the female sealing surface, leaving an axial distance greater than zero between the free end and a transition region outwardly of the female sealing surface, and a radial distance greater than zero between the female sealing surface and a chamfer at the free end, the groove including borders formed by the chamfer and a portion of the transition region protecting the female sealing surface prior to makeup.
