IPSCO CONNECTIONS
RUNNING MANUAL

Care is to be taken to prevent thread compound from going into the pin and box center shoulder seal
groove to avoid dope squeeze and anomalies in the torque turn graph.
Make-up Torque
ULTRA™ SF and SFII connections shall be made up to the torque specified on the most current
Connection Data Sheet.
The specified minimum make-up torque in the data sheet is the minimum torque to which the
connection should be assembled the first time.
The specified optimum make-up torque in the data sheet should be used as the target make-up
torque for optimum performance.
The specified maximum make-up torque in the data sheet should be used as the highest
recommended make-up torque for normal operations.
Add 10% to the optimum make-up torque when using thread locking compound. A torque shoulder
must be visible for proper make-up. Apply the thread locking compound to the threads only and
apply running compound to the seal area.
Make-up RPM
Initial RPM shall start in high gear with a low torque and high RPM.
Switch to low gear before the seal engagement appears in the torque turn graph.
Power tongs should remain in low gear and at a constant RPM once the seal engages.
The below table lists the approximate recommended make-up RPM for the ULTRA™ SF and SFII
connections.
