Abstract
A threaded tubular connection is provided. The connection includes a male tubular element provided with a male threaded portion and a female tubular element provided with a female threaded portion. The male threaded portion and the female threaded portion each include self-locking threads having a crest, a load flank, a stabbing flank and a root, a load flank lead of the self-locking threads being larger than a stabbing flank lead of the self-locking threads such that in a tightened position of the threaded tubular connection, the load flanks and the stabbing flanks of the male self-locking threads are engaged in tight contact with the load flanks and the stabbing flanks of the female self-locking threads. A transfer zone is axially disposed between the threaded portions and a free end of at least one of the tubular elements, while being axially spaced from the threaded portions.
