The surface areas available for absorbing compressive loading of a threaded connection (30) are increased by increasing the engaged area of a torque shoulder (35) in the connection (30) and by reducing the spacing between the stab flanks of the threads (33, 34). The areas are increased by increasing the dimensions of the components and by decreasing the machine tolerances permitted in manufacturing the components. The gap (x) in the connection adjacent the torque shoulder is reduced so that the contact surface area of the torque shoulder is increased while the close proximity of the surrounding cylindrical walls of the connection reduces voids that can receive plastic deformation of the torque shoulder comers. The surfaces adjacent the torque shoulder are cylindrical (37, 38) in shape rather than being tapered to reduce machining costs and increase the speed of manufacture of the connection.

La présente invention concerne une augmentation de surfaces, permettant à un raccord fileté (30) d'absorber une charge de compression. Cette augmentation de surfaces est réalisée au moyen d'un accroissement de la surface d'engagement d'un épaulement de torsion (35) dans le raccord (30), et par réduction de l'espace entre les flancs guides des filetages (33,34). Le surfaces sont augmentées par accroissement des dimensions des composants et par diminution des tolérances d'usinage machine lors de la fabrication des composants. L'espace (x) dans le raccord adjacent à l'épaulement de torsion est réduit de telle manière que la surface de contact de l'épaulement de torsion soit augmentée alors que la grande proximité des parois cylindriques entourantes du raccord permet de réduire des vides pouvant recevoir une déformation plastique des coins de l'épaulement de torsion. Les surfaces adjacentes à l'épaulement de torsion sont de forme cylindrique (37,38) plutôt que conique afin de réduire les coûts d'usinage et augmenter la rapidité de fabrication du raccord.
