Threaded tubular connection for casing

A threaded tubular connection, comprising:

• a tubular female end extending from a main body of a first tubular member, the tubular female end comprising a female external thread close from a female free end, a female internal thread closer to the main body of the first tubular member, and a female intermediate sealing surface between the female external thread and the female internal thread;
• and
• a tubular male end extending from a main body of a second tubular member, the tubular male end comprising a male external thread close to the main body of second tubular member, a male internal thread close to a male free end and a male intermediate sealing surface between the male external thread and the male internal thread,
• wherein the male external thread and the male internal thread are configured to respectively interlock by thread engagement with the female external thread and the female internal thread, and male and female sealing surfaces form an intermediate metal-to-metal seal when the threaded tubular connection is made up,
• wherein the tubular female end comprises a minimal outer diameter at the intermediate metal-to-metal seal location, the minimal outer diameter being smaller than respectively an external and an internal outer diameter, the external outer diameter being located above at least one thread root of the female external thread, the internal outer diameter being located above at least one thread root of the female internal thread,
• wherein the threaded tubular connection includes a longitudinal axis
• wherein the minimal outer diameter is constant over a cylindrical surface, the cylindrical surface extending from a first position on the longitudinal axis where the female external thread ends to a second position on the longitudinal axis where the female internal thread begins.
