TTUS

Our TTUS, Upset Shoulder connection is a threaded-and-coupled connection. Pin ends are upset to provide increased strength in tension, torque and compression. The connection provides for a more robust design needed when higher torque, higher compression and rotation are needed through a bend, to drill out a plug or when an API 8rd connection is not sufficient. The 7-tpi (threads per inch) thread design is similar to a buttress thread used on casing, but adapted for tubing sizes. The added torque shoulder gives the connection a stationary mechanical stop to support the higher torque and compression loading.

TORQUE-TO-YIELD

Torque-to-yield testing was performed to verify the torsional limits of all TTUS connections.
