| 摘要 |
<p>The invention relates to an assembly for producing a threaded joint, comprising first and second tubular components having axis of rotation (10). One of the ends (1, 2) of each of the aforementioned components is provided with a first threaded zone (3, 3a; 4, 4a) formed on the outer or inner peripheral surface of the component, depending on whether the threaded end is male or female, and the threaded zones can be screwed to one another, said ends (1, 2) terminating at an end surface (7, 8). The assembly is characterised in that, according to a longitudinal cross-section extending through axis (10), at least one of the threaded zones allows a profile corresponding to a continuous concave curved portion (C) extending over at least 10% of the length of the engaged threads of the threaded zone.</p> |
