API Buttress thread form connection with a taper of 1:16 and a lead of 5TPI, enables high connection strength.
For TP-BM, mill end is screwed to the center of the coupling, field end will be screwed and contacted to the mill end. For TP-BM(S), the torque shoulder provides accurate power tight make-up.
TP-BM Premium Connection Makeup torque
TP-BM and TP-BM(S) ensures accurate make-up stop, provides higher over-torque resistant ability & better bending resistant ability. The over-torque ability is 2.5~3.5 times of API BC connection.
TP-BM Premium Connection Internal Profile
Internally flush design. The streamlined internal profile minimizes turbulence and energy loss due to high-velocity gas flows.
TP-BM Premium Connection Coupling Design
A shorter design compare to API BC ensures pin-to-pin contact connection. Because the coupling covers the vanishing threads therefore the connection tensile efficiency is maximized.
TP-BM Connection Lower Stress Design
The lower stress design makes the connections reliable in corrosive conditions.
