The end includes a terminal surface and the threaded zone includes, over at least a portion, threads including, when viewed in a longitudinal section passing through an axis of the tubular component, a thread crest, a thread root, a load flank, and a stabbing flank, such that a respective axial width of thread crests decreases in a direction of the terminal surface while a respective axial width of thread roots increases when considered in the same direction. At least one of a profile of the load flank and a profile of the stabbing flank of a thread portion includes, as a contral portion, a continuous curve provided with a point of inflection such that the profile with the point of inflection in convex at the thread crest and concave close to the thread root.

摘要： A set for producing a threaded connection and a threaded connection. The set includes first and a second tubular components with an axis of revolution, one of their ends including a threaded zone formed on the external or internal peripheral surface of the component depending on whether the threaded end is of male or female type, the ends finishing in a terminal surface orientated radially with respect to the axis of revolution of the tubular components. The threaded zones include threads including, viewed in longitudinal section passing through the axis of revolution of the tubular components, a thread crest, a thread root, a load flank, and a stabbing flank, the width of the thread crests of each tubular component reducing in the direction of the terminal surface of the tubular component under consideration, while the width of the thread roots increases. The lead of the male stabbing flanks and/or load flanks is different from the lead of the female stabbing flanks and/or load flanks.

摘要： A tubular threaded joint which has excellent resistance to compression and which permits easy tightening operation in the field in a vertical state comprises a pin having a male threaded zone and a box having a female threaded zone. The pin or the box has an end shoulder surface on its end, and the other member has a shoulder surface which abuts against the end shoulder surface. The screw threads of the male threaded zone and the female threaded zone are trapezoidal threads having a crest, a load flank, and a stabbing flank. The lip length, which is the distance in the axial direction of a member having an end shoulder surface between the end shoulder surface and the closest engaged thread to that surface, is at least 140 times the stabbing flank clearance, which is the distance in the axial direction between the stabbing flanks of the male thread and the female thread when the load flanks of the male and female threads contact each other. The stabbing flank of the male thread is preferably chamfered.

摘要： A tubular joint in which radial expansion caused by the passage of an expander, inclined shoulder fittings formed respectively on a peripheral surface of the female element facing radially inwards and on a peripheral surface of the male element facing radially outwards, are subjected to a relative axial displacement towards each other to be urged into sealed mutual contact with radial interference. The tubular joint is, for example, useful in hydrocarbon wells.

摘要： A threaded connection includes at least one contact zone axially separated from threadings in which a male and female elements are in sealed contact via bearing surfaces respectively constituted by a cambered surface and by a tapered surface. Such a contact zone ensures a seal against fluids despite positional inaccuracies in the male and female elements at the end of makeup, due to the geometrical characteristics of the threadings. Such a threaded connection can find, as an example, application to oil and gas wells.
