Title (EN) TUBE COUPLING
(FR) RACCORDEMENT DE TUBES
Abstract: front page image
(EN)The present invention relates to a pipe coupling, designed as a thread jointing having a male part (1), a female part (7) and a jointing ring (11), disposed therebetween, which parts are coaxially disposed and penetrated by the coaxially disposed pipe (10), which is to be connected, said jointing ring comprising a front portion (12) with a front conical rotation-symmetrical surface (12a), which abuts an also conical internal surface (4a) in said male part, a rear rigid portion (20) in contact with said female portion as well as a deformation-portion (15), which is positioned between said front and said rear portions and designed to be able to be deformed when subjected to forces in the axial direction. Said deformation-portion (15) is designed as a comparatively thin wall (21), which connects the external periphery of said front portion (at 18) with the internal periphery of said rear portion (at 17).
(FR)L'invention concerne un raccordement de tubes se présentant sous la forme d'un raccordement fileté doté d'une partie mâle (1), d'une partie femelle (7) entre lesquelles est disposée une bague (11) de raccordement, et lesquelles sont disposées coaxialement et pénétrées par le tube (10) coaxial à raccorder. Ladite bague de raccordement comprend une partie frontale (12) comportant une surface (12a) symétrique de rotation conique frontale, aboutant une surface interne (4a) également conique dans ladite partie mâle, une partie rigide arrière (20) en contact avec ladite partie femelle, ainsi qu'une partie à déformation (15) positionnée entre lesdites parties frontale et arrière et conçue pour être déformée lorsqu'elle est soumise à des forces dans le sens axial. Ladite partie à déformation (15) se présente comparativement comme une mince paroi (21), reliant la périphérie externe de ladite partie frontale (à 18) à la périphérie interne de ladite partie arrière (à 17).
