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 screw joint for an oil well pipe is equipped with either one, or both, of an inner surface shoulder portion and an outer surface shoulder portion comprising a seal portion and a torque shoulder portion, and satisfies further the following conditions 1 and 2: 1) effective diameter of seal formation surface before fastening is greater on the pin side than on the box side; and 2) inclination of torque shoulder formation surface is smaller on the pin side than on the box side, and difference DELTA theta of the inclinations is at least 0.5 DEG and not greater than 4.0 DEG . The screw joint for the oil well pipe of this invention is excellent in gas sealability and clearance corrosion resistance. The production cost is equal to that of conventional screw joints, and handling is easy, too. This screw joint is extremely suitable for probing and mining of burried matters at a depth and at a higher pressure and burried matters containing high corrosive impurities such as gases and crude oils.

摘要： A screw joint for oil well pipes, for preventing degradation in gastightness caused at the time of tension after axial compression, and a method of manufacturing the same. A screw joint for oil well pipes, formed with a seal portion and a torque shoulder portion, is such that a length (15) of a tip end of a thick-walled pin portion having an inner diameter determined by the formula (1) is not less than a length (16) extending to a position of the pin portion corresponding to the seal portion but not more than a half of a length (17) of the pin portion, an inner diameter of the remaining pin portion near a pipe body is equal to that of the pipe body, an inner diameter increases gradually from the thick-walled pin portion to the remaining pin portion, and an inner diameter of a box portion on the torque shoulder portion is equal to that of the tip end of the thick-walled pin portion in a state where the joint is fastened. Formula (1) is: do > dx >/= do -, where dx (mm) designates an inner diameter of the thick-walled pin portion, and do (mm) designates an inner diameter of the pipe body.
