Performances

Threaded Connection

--A modified hook thread profile with 4º reverse angle on the load flank, which provide the connection with superior tension strength and increase its resistance to compression.

Metal-to-Metal Seal

--Large angle metal-to-metal seal system offers excellent gas-tight sealing, even under the most severe combined loads. The seal integrity remains constant after repeated make-ups and break-outs.

Reverse Angle Torque Shoulder

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

Streamlined Internal Profile

--A pin ID chamfer, tight tolerances on the coupling center combined with a long shoulder will minimize turbulence and energy loss inside the connection for high-velocity gas flows.

Coupling Design

--The design owns 100% efficient connection performances.

Connection Low Stress Design

--Connection low stress design can ensure that it can be safe under corrosive environment.
