Title (EN) THREADED CONNECTION INCLUDING AN INTERMEDIATE SHOULDER
(FR) RACCORD FILETÉ COMPRENANT UN ÉPAULEMENT INTERMÉDIAIRE
Abstract:
(EN) A threaded tubular connection (10) comprises a first tubular component (12) and a second tubular component (14). The first tubular component (12) includes a female portion (16) defined on an interior surface of the first tubular component. The female portion includes an inner threaded portion and an outer threaded portion which are offset radially with respect to a longitudinal axis of the first tubular component by a first shoulder (26). The second tubular component includes a male portion (18) defined on an exterior surface of the second tubular component (14). The male portion (18) is to be inserted into the female portion (16), and includes an inner threaded portion and an outer threaded portion which are offset radially with respect to a longitudinal axis of the second tubular component by a second shoulder (28). The second shoulder (28) is to abut the first shoulder (26) once the male portion (18) is connected to the female portion (16).
(FR) Cette invention concerne un raccord tubulaire fileté, comprenant un premier composant tubulaire et un second composant tubulaire. Le premier composant tubulaire comprend une partie femelle définie sur une surface intérieure du premier composant tubulaire. La partie femelle comprend une partie filetée interne et une partie filetée externe qui sont décalées radialement par rapport à un axe longitudinal du premier composant tubulaire par un premier épaulement. Le second composant tubulaire comprend une partie mâle définie sur une surface extérieure du second composant tubulaire. La partie mâle peut être insérée dans la partie femelle, et elle comprend une partie filetée interne et une partie filetée externe qui sont décalées radialement par rapport à un axe longitudinal du second composant tubulaire par un second épaulement. Le second épaulement est destiné à buter contre le premier épaulement quand la partie mâle est reliée à la partie femelle.
