The Tubing Swivel allows surface connections to remain in place while the work string is rotated and moved vertically. It is primarily used in conjunction with the “SST’ to provide a means of operating the by-pass valve while the treating line is connected.
It can also be used to facilitate the operation of other Tryton packers, cementing or for light drilling.
OPERATION
When using this swivel, it is strongly recommended that the treating line be secured to the Tubing Swivel with a suitable safety chain or cable.
