Patent number: 10563466Abstract: A threaded connection including first and second tubular components configured for exploration or operating a hydrocarbon well; the first tubular component including an external abutment, a male threaded connection portion extended by a non-threaded terminal portion defining an internal abutment at its axial end; the second tubular component including a female end defining at a free end a bearing surface forced against the external abutment, a female threaded connection portion made up with the male threaded connection portion and terminating in an internal shoulder forced against the internal abutment, an initial non-threaded portion connecting the female threaded connection portion to the internal shoulder, which includes a maximum radial interference locally forming a sealing surface located between the male threaded connection portion and the internal abutment, and located at a non-zero distance from the internal abutment, the distance being more than half of an axial distance of the terminal portion.Type: GrantFiled: October 14, 2015Date of Patent: February 18, 2020Assignee: Tuboscope Vetco (France) SASInventors: Romain Branly, Fabien Carrois

Patent number: 9816646Abstract: A threaded connection including first and second tubular components, each including a respective male and female end, the male end includes at least one threaded zone on its external peripheral surface and ending in a terminal surface, the female end includes at least one threaded zone on its internal peripheral surface and ending in a terminal surface, the threaded zones including, over at least a portion of their length, threads each including, viewed in longitudinal section passing through the axis of the tubular component, a thread crest, a thread root, a load flank, and a stabbing flank. Profiles of the male and female load flanks, viewed in longitudinal section passing through the axis of revolution of the connection, are a continuous curve with a convex or concave form, the profile of the male flanks being complementary to that of the female flanks over at least 70% of the continuous curve.Type: GrantFiled: December 12, 2011Date of Patent: November 14, 2017Assignees: VALLOUREC OIL AND GAS FRANCE, NIPPON STEEL & SUMITOMO METAL CORPORATIONInventors: Fabien Carrois, Yann Gallois, Francois Conrad
