摘要： Le joint fileté tubulaire supérieur comporte au moins sur un élément fileté une surface distale de butée (7) en extrémité libre d'un élément fileté et une portée d'étanchéité sur lèvre (5) à distance donnée du filetage. La lèvre comporte un appendice (13) qui prolonge la lèvre vers son extrémité libre au-delà de la portée d'étanchéité sur lèvre (5) de manière à ce que la lèvre possède à la fois une forte raideur radiale et une faible raideur axiale. Il en résulte des performances accrues d'étanchéité du joint fileté sous pression et/ou sous traction et d'autres avantages (précision sur le couple réel de vissage, résistance mécanique en compression axiale, effet de barrière aux chocs, tolérance à l'engagement des éléments filetés).
摘要翻译：本发明涉及一种优质的管状螺纹接头，其至少包括螺纹元件，螺纹元件的自由端邻接的远端表面（7）和唇部（5）上与座螺纹间隔开给定距离的座。唇部包括突起（13），其将唇缘朝向其自由端延伸超过唇缘（5）上的座，使得唇缘具有高径向刚度和低轴向刚度，从而导致螺纹接头下的密封性能增强压力和/或牵引力等优点（实际紧固扭矩精度，轴向压缩机械强度，冲击阻挡效应，螺纹元件的接合公差）。

摘要： The invention concerns a premium tubular threaded joint comprising at least on a threaded element a free-end abutting distal surface (7) of a threaded element and a seat on the lip (5) spaced apart by a given distance from the threading. The lip includes a protuberance (13) which extends the lip towards its free end beyond the seat on the lip (5) so that the lip has both high radial stiffness and low axial stiffness, thereby resulting in enhanced sealing properties of the threaded joint under pressure and/or traction and other advantages (real tightening torque accuracy, axial compression mechanical strength, impact barrier effect, engagement tolerance of the threaded elements).

摘要： The invention concerns an integral threaded or sleeved assembly of two metal tubes provided or not with an internal coating and in particular designed to contain internally a corrosive fluid. The assembly male element(s) (1) each comprise in the direction of their open end a threaded part (13) and an unthreaded part, the latter comprising successively a sealing metal surface (14), a ring-shaped transverse support surface (15) and a nozzle surface (16) which joins the tube internal peripheral surface (10) via a radial surface (17) called inner end. The female element(s) comprise elements corresponding to the male elements and co-operating therewith. A sealing ring (40) is set between the inner end ring-shaped surfaces (17), (17') and prevents the liquid phase from seeping into the assembly. The assembly is characterised in that it comprises sealing metal male surfaces (14) arranged between threaded part (13) and support surface (15) and by the presence of a clearance between the nozzle outer peripheral surface (16) and the reinforcement inner peripheral surface (26) opposite the female element (2). The invention includes in particular special solutions when the tubes (10') are provided with an internal coating particularly in the form of tubes with inner lining (51), (51'). In such a case, flanges (60), (60') are provided to provide continuity for the coating on the ring-shaped end surfaces.
