UDT-Swift is a heavy duty threaded connector for use in exploration and platform casing strings where high strength and pressure integrity are important. Compared to other connectors of similar performance, UDT-Swift requires low make-up torque and can be assembled using standard rig tongs. It has mechanical strength characteristics higher than those of the casing pipe.

UDT-Swift combines a rugged, double-start thread form with a deep stabbing design to eliminate cross threading. The double-start thread reaches full pre loaded make-up in 1-1/2 rotations. Full make up is visually confirmed by inspecting external indicator faces. Sealing is provided by an integral metal-to-metal seal & with an elastomer O-ring secondary seal.


UDT-Swift connectors are typically made from 70 ksi to 110 ksi and can be used for all types of operations based on customer requirement.
