摘要 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.
