High Torque Double Shoulder Threaded Connection

Product Description

Under challenging well conditions, drilling tools are often subjected to high torsional stress, resulting in premature failure and drilling accidents. To cater for these applications, Tianhe has introduced two types of high torque double shoulder threaded connections (TT Type and THDS Type).

Features of TT type double shoulder threaded connection:-

1. Higher torsional strength and bending stiffness
2. Even distribution of force on the threads
3. Tool joints with double shoulder threaded connections are more rigid, stronger and has greater torque capacity
4. Smooth transition between the pin and box threaded connections, creates a streamlined ID profile. This allows smoother fluid flow during drilling with minimized turbulence, improving the hydraulic performance, minimizing thread erosion and reducing drill collar failure
5. Excellent sealing performance

Features of THDS type double shoulder threaded connection:-

1. High torsional resistance
2. Interchangeable with API connections of comparable sizes
3. Excellent sealing performance
4. Minimize pressure loss
