摘要： An expandable threaded connection includes: first and second tubular components including respective male and female ends including respective first and second and third and fourth threaded zones, insertion regions, first and second annular tongues, prominent abutment faces, and first and second concavities; the first and second tongues are respectively engaged in the second and first concavities in a made up condition, the abutment face of at least one tongue in contact with at least one concavity; the male end including a first surface between the first threaded zone and the first tongue, and the female end including a second surface between the third threaded zone and the second concavity; in the made up condition, the first and second surfaces define an annular space include large and small radial dimension zones which, after expansion, can form a metal-metal contact seal, the first tongue bearing on the second tongue.
