    • A cap (10) comprising a female threading (11) matched with that (2) of a first element is made up onto the first male threaded element (1) of a component to be tested so as to compress a sealing ring (16) between metal surfaces (7, 15) of the first element and the cap, and a test pressure is established inside said component, the male element (1) having an annular lip (3) which is capable of deforming radially outwardly under the effect of said test pressure. Between the radially outward surface (6) of the lip (3) and the facing surface (19) of the cap, at the end of makeup there exists a clearance having a value (j) which has been selected sufficiently small so that, under the effect of the test pressure, the lip bears on said facing surface without undergoing plastic deformation.

    • 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.
    • 本发明涉及一种由两个金属管构成的整体螺纹或套管组件,该金属管具有或不具有内部涂层,并且尤其被设计为内部含有腐蚀性流体。 组件公元件1各自在其开口端的方向上包括螺纹部分13和无螺纹部分,所述无螺纹部分依次包括密封金属表面14,环形横向支撑表面( 15)和经由称为内端的径向表面(17)连接管内周表面(10)的喷嘴表面(16)。 母元件包括对应于公元件并与其配合的元件。 密封环(40)设置在内端环形表面(17),(17')之间并防止液相渗入组件中。 该组件的特征在于,其包括布置在螺纹部分(13)和支撑表面(15)之间的密封金属阳表面(14),并且通过喷嘴外周表面(16)和加强内周表面 (26)与母元件(2)相对。 当管(10')设置有内部涂层,特别是具有内衬(51),(51')的管的形式时,本发明特别包括特殊的解决方案。 在这种情况下,设置凸缘(60),(60')以为环形端面上的涂层提供连续性。
