3T.P.I coarse thread enable fast make-up without cross-thread
Torque shoulder provides accurate power-tight make-up
Coarse thread form with a taper of 1:12 and a lead of 3.T.P.I. enables high connection strength, fast and easy running without cross-threading.
The torque shoulder provides accurate power tight make-up, which also enables connection to withstand higher compression load.
The streamlined internal profile minimizes turbulence and energy loss due to high-velocity gas flows.
Because the coupling covers the vanishing threads therefore the connection tensile efficiency is maximized.
Low Stress Design
The low stress design makes the connections reliable in corrosive condition.
