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.

The two nozzles (1a,1b) are disposed at different positions at least in the axial direction of the steel pipe(11) at angles which are sloped such that the sprayed streams from the nozzles(1a,1b) approach each other. By using this coating apparatus, it is possible to form a UV cured resin coating on the outer or inner surface of a threaded end portion of a steel pipe with a uniform thickness.

摘要： The gap L (mm) which is the smaller of the gap L 1 (mm) between the crest 1a of a tapered male thread 1 and the root 2b of a tapered female thread 2, and the gap L 2 (mm) between the root 1c of the tapered male thread 1 and the crest 2c of the tapered female thread 2, the load flank angle α(°) and the stab flank angle β(°), and the axial gap δ(mm) which forms in the widthwise direction and is the difference between the thread ridge width of the tapered male thread 1 and the thread valley width of the tapered female thread 2 threadingly engaged therewith have the following relationship δ ≤ L·(tanα + tanβ)
When interference of the threaded portions is necessary, the initial set thread interference H is H > 2L.
As a result, a thread having sufficient resistance to tensile force and compressive force can be easily manufactured within manufacturing tolerances. In particular, it has good sealing properties and increased reliability as a threaded joint for an oil well pipe having a metal seal portion.
