Description of Premium Connection TP-QR

Threaded Connection

Coarse thread form with a taper of 1:12 and a lead of 3T.P.I, enables high connection strength, fast and easy running without cross-threading.

Torque Shoulder

The torque shoulder provides accurate power tight make-up, which also enables connection to withstand higher compression load.

Internal Profile

The streamlined internal profile minimizes turbulence and energy loss due to high-velocity gas flows.

Coupling Design
