Lift Nubbin For Flush Joint Casing
The UMS Flowell Lift Nubbin for flush joint casing allows handling of flush joint casing and tubing. The Flush Joint Casing Clamp Nubbins have a pin thread to mate with the corresponding flush joint box thread on the casing or tubing.
A 4.75 ton swivel allows single joints to be lifted with the tugger line or crane without the need for single joint elevators. A shoulder on the lift nubbin acts as a dummy coupling and allows the string to be handled with side door or centre latch elevators.
If slip type elevators are used, the dummy coupling shoulder acts as a stop collar in the event that unplanned string slippage occurs.
