Performances

Threaded Connection

--mproved Buttress thread with a taper of 1:16.

The clearance at the top of the thread crests minimize thread galling and avoid the tapping of compound inside the threads.

Metal-to-Metal Seal

--Metal-to-metal seal surface can provide enough contact length and pressure.

The seal system offers excellent gas-tight sealing, even under the most combined loads.

Reverse Angle Torque Shoulder

--The reverse angle torque shoulder provides a positive torque stop, which allows accurate power tight make-up and minimizes hoop stresses in the connection strength.

Streamlined Internal Profile

--A pin ID chamfer, tight tolerances on the coupling center combined with a long shoulder will minimize turbulence and energy loss.

Coupling Design

--Joint efficiency is more than 100% and coupling critical section is greater than pipe body section.

Connection Low Stress Design

--Connection low stress design ensures more safe under corrosive environment.
