PROBLEM TO BE SOLVED: To provide a connection joint of a steel pipe capable of easily carrying out a fitting test for a screw-type male joint and a screw-type female joint.SOLUTION: A connection joint 1 of a steel pipe related to the present invention is composed of a screw-type male joint 3 and a screw-type female joint 5, which are attached to end parts of steel pipes 7 to connect the steel pipes 7. The inner peripheral surface of the male joint 3 and the female joint 5 is provided with a recess 9 that is designed to transmit torque in the screw-rotating direction by bearing pressure.SELECTED DRAWING: Figure 1
【課題】ネジ式の雄継手と雌継手に関して、嵌合試験を容易に行うことのできる鋼管の接合継手を得る。【解決手段】本発明に係る鋼管の接合継手１は、ネジ式の雄継手３と雌継手５からなり、鋼管７の端部に取り付けられて鋼管７を接合する鋼管の接合継手１であって、雄継手３と雌継手５の内周面にネジ回転方向のトルクを支圧伝達できる凹部９を有することを特徴とするものである。【選択図】 図１
