  • Patent number: 11946572
    Abstract: A threaded tubular connection comprises a first tubular (12) component and a second tubular component (14). The first tubular component (12) includes a female portion (10) defined on an interior surface of the first tubular component. The female portion includes an inner threaded portion (16d) and an outer threaded portion (16b) which are offset radially with respect to a longitudinal axis of the first tubular component by a first shoulder (26). The second tubular component (14) includes a male portion (18) defined on an exterior surface of the second tubular component. The male portion is to be inserted into the female portion, and includes an inner threaded portion (18d) and an outer threaded portion (18b) which are offset radially with respect to a longitudinal axis of the second tubular component by a second shoulder (28). The second shoulder is to abut the first shoulder once the male portion is connected to the female portion.

  • Patent number: 11473373
    Abstract: A threaded connection includes a first and a second tubular component made up one with the other. A male element of the first component includes, on its external peripheral surface, a male inner lip including an inner mg with a minimum thickness Epi and a male threaded zone. One inner end of the male threaded zone is at a non-zero axial distance (Li) from a male distal end. A female element of the second component includes, in succession over its internal peripheral surface, a female inner recess disposed facing the male inner lip and a female threaded zone, such that in the made up position of the connection, a radial clearance subsists between the male inner ring and the female inner recess and an internal seal is formed locally between the male inner lip and the female inner recess. The connection is such that 10%?Epi/Li.
