Premium OCTG Casing Connection/RTH-8t
Structure
- The unique combination of a metal-to-metal seal and a special relief groove in coupling provides pressure integrity for both internal and external pressure in moderate to heavy wall tubular applications.
- The hooked thread form provides excellent resistance against tensile loads, bending moments and external pressures under a variety of load combinations. The thread geometry provides for easy stabbing, quick, trouble-free run.
- Torque shoulder stop improves compressive, torsional and leak resistance. The inside diameter of pin is profiled to match the J area of the coupling. This provides a smooth bore through the connection.
Performance
- Higher connecting strength: thread is hook type to resist jump-out, it is designed for 100% efficiency under tension.
- Excellent seal ability:the multiple seal arrangement, The unique combination of a metal-to-metal seal and a close-tolerance thread-seal ensures gas-tight sealing integrity to 100% of the rated burst and collapse of the pipe body.
- High bending resistance: Thread is hook type, along with the reverse torque shoulder. This design exhibits a high bending, compression resistance for connections of this class.
- Inner flat design reduces the air and liquid turbulence in the pipe, so make the energy loss lower.
