Abstract
Threaded tubular connection for the casing of hydrocarbon wells obtained by makeup of a male tool joint with a female tool joint, the connection comprising a threaded portion (16a, 18a), such that the male and respectively female threaded portions each comprise a helix provided with a load flank, a thread crest, a stabbing flank, a thread root, such that a pitch of the load flank (LFLp, LFLb) and a pitch of the stabbing flank (SFLp, SFLb) fulfils the following condition: [Math 22] SFLb = LFLb = SFLP = LFLP = k, A tooth width (Wtp) of the male helix and a tooth width of the female helix (Wtb) are such that [Math 23] or [Math 24] and [Math 25] Wtp + Wtb < k
