    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 connection for the oil country tubular goods, according to the invention, is provided with either an internal shoulder or an external shoulder or both, each comprising a seal portion and a torque shoulder, and characterized by satisfying the following conditions (1) and (2):(1) A pitch diameter of the seal forming face on the pin is larger than the same on the box; and(2) An inclination of the torque shoulder forming face on the pin is smaller than the same on the box, the difference in the inclination between the both sides being in the range of 0.5 to 4.0.degree..The threaded connection for the oil country tubular goods, according to the invention, has excellent gas tightness and crevice corrosion resistance. Moreover, the production cost thereof is equivalent to that of conventional threaded connections and it is easy to handle. Hence, it is quite suited for use in exploration and exploitation of deposits located at great depths under high pressures and deposits such as gas, crude oil, or the like containing highly corrosive impurities.
