Internal flush
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.
