Abstract:
A threaded connection including first and second tubular components including respective male and female ends including a distal surface and a threaded zone. The threaded zone of the male end is threaded into the threaded zone of the female end. The threaded zones include respective male and female threads having increasing width from the distal surface and including load flanks having negative angles over at least a portion of their radial dimension, and stabbing flanks, with a radial clearance in the connected state between crests of the male threads and roots of the female threads and/or between crests of the female threads and roots of the male threads, with an axial clearance in the connected state between the stabbing flanks of the male and female threads. The distal surface of the male and/or female end is brought into axial abutting contact against a corresponding abutment surface.
