IJ- Integral Joint - Thread Plug and Ring Gages

Integral joint tubing incorporates external thread and internal threads on both ends of the pipe thus eliminating the need for couplings to connect the pipe. Cylindrical surface, conical surface, spherical surface and reverse circular cone step surface are arranged successively on the outer end of the external thread and inner end of the internally threaded parts. The metal surfaces form a sealing structure and the first step. On the other side of the external and the internal joints there is a second step which forms the major anti‐torque step. The second step and the first step form a double‐step structure. Integral joint connection cut the number of connections in half. Integral joint connections typically have higher torque capacity than the threaded and coupled connection. Integral joint connections utilize metal sealing and two anti torque steps for improved sealing, anti torque capability and connection strength.
