Premium Threaded Connections
TMK UP Series
The Lite Series boasts a comprehensive line of semi-premium connections designed to outperform standard API connections.
Semi-premium threaded and coupled connection with a shouldered coupling. Fully compatible with API Buttress but with enhanced operational properties. Available globally.
Standard sizes: 4-1/2” – 13-3/8”
Semi-premium threaded and coupled connection with a shouldered coupling. Specially designed for large diameter casing. Enhanced stabbing and make-up compared to API Buttress. Available globally.
Standard sizes: 8-5/8” – 20”
TMK UP Simplex – threaded and coupled connection with increased performance characteristics in reference to Buttress threads. Designed with an internal pin-to-pin stop for 100% compression efficiency and torsional stability. The connection is designed for casing rotation during run-in-hole operation and cementing.
Threaded and coupled connection with increased performance characteristics in reference to Buttress threads. TMK UP CWB can be assembled with Buttress connections without the use of special crossover subs, that makes the TMK UP CWB an excellent alternative to Buttress connection with a wide range of application: string rotation during run-in-hole operation, cementing operations and also drilling with casing. The key difference from TMK UP CWB is increased thickness of the torque shoulder, which provides higher resistance to torsional loads. Enlarged torque shoulder for high torsional capacity and increased compression performance.
Standard sizes: 4-1/2’’ – 13-3/8’’
