The invention concerns a threaded connection (1) comprising a first and a second tubular component, the first component comprising a male end (3) provided on its outer peripheral surface with, in succession, a threaded zone (5), a sealing surface (13) then a terminal surface (15) finishing in an abutment surface (7) which is orientated radially with respect to the axis of revolution (20) of the connection (1), the second component comprising a female end (2) provided on its inner peripheral sur-face with, in succession, a threaded zone (4), a sealing surface (12) then a recess (10) finishing in an abutment surface (8) which is orientated radially with respect to the axis of revolution (20) of the connection, the threaded zone (5) of the male end (3) being made up into the threaded zone (4) of the female end (2) such that the sealing surfaces (12) and (13) are in interfering contact, as are the abutment surfaces (7) and (8), the space between the terminal surface (15) and the recess (10) defining a volume (17), characterized in that the volume (17) is at least partially filled with a filling material (M). The invention also concerns a method for producing such a connection.
Linvention concerne un raccord fileté (1) comprenant un premier et un second composant tubulaire. Le premier composant comprend une extrémité mâle (3) comportant successivement, sur sa surface périphérique, une zone filetée (5), une surface de scellement (13), puis une surface terminale (15) se terminant par une surface de butée (7) orientée radialement par rapport à laxe de révolution (20) du raccord (1). Le second composant comprend une extrémité femelle (2) comportant successivement, sur sa surface interne, une zone filetée (4), une zone de scellement (12), puis un renfoncement (10) se terminant par une surface de butée (8) orientée radialement par rapport à laxe de révolution (20) du raccord, la zone filetée (5) de lextrémité mâle (3) étant amenée dans la zone filetée (4) de lextrémité femelle (2) de façon que les surfaces de scellement (12) et (13) soient en contact dinterférence, à la manière des surfaces de butée (7) et (8), lespace entre la surface terminale (15) et le renfoncement (10) définissant un volume (17), caractérisé en ce que ledit volume (17) est au moins partiellement rempli dun matériau de remplissage (M). Linvention concerne également un procédé de fabrication dun tel raccord.
