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 threaded joint for steel pipes constituted by a pin having male threads and a box having female threads is improved with respect to ease of insertion of the pin and galling resistance of the threaded portions. The stabbing flanks of the threads in a complete thread portion of one of the pin and box has a two-step stabbing shape having a chamfer. The two-step stabbing shape has a stabbing flank angle α of 5 - 45° and a chamfer angle β of 20 - 60°. The ratio h/H of the chamfer height h to the thread height H of the pin is 0.25 - 0.50, or the ratio of the cross-sectional area of the chamfered portion to the overall cross-sectional area of the stabbing flank is made at least a value corresponding to a chamfer height ratio h/H of 0.25 and at most a value corresponding to a chamfer height ratio of 0.50.

摘要： A first axial abutment surface (6) formed at the free end of an annular lip (5) of a threaded male element (1) and a second axial abutment surface (9) formed at the end of a housing (7) of a threaded female element (2) have a same axial half-sections (S) the inclination of which varies progressively in the radial direction. Such a configuration of the axial abutment surfaces optimizes the radial thrust exerted on the end of the lip depending on its thickness, in order to obtain an increased radial interference between the respective sealing surfaces (10, 12) of both elements. Application to hydrocarbon wells.

The unthreaded metal contact portion includes a sealing surface 5, 8 and a shoulder surface 9, 10, 11, 12. The shoulder surface of the pin is located on the end surface of the pin. A non-contacting region 13 in which the pin and the box do not contact each other is present between the sealing surfaces and the shoulder surfaces of the pin and the box. The threaded joint has one or more grooves formed in the shoulder surface of at least one of the pin and the box and extending to the non-contacting region and to the interior of the threaded joint. At least the contact surface of at least one of the pin and the box has a solid lubricating coating exhibiting plastic or viscoplastic rheological behavior formed thereon. The total volume V (mm 3 ) of the grooves and the coating weight W (g) of the solid lubricating coating satisfy the equation V/W ≥ 24 (mm 3 /g).
