Tension Tubing Hangers
Printable Version

The Tension tubing head and hanger system was designed to allow the tubing string to be lowered into the production casing in order to provide an overpull of the string weight prior to engaging the load pins in the landed position. This compensates for elongation due to temperature variations during the completion of the well to ensure that the tubing string is not exposed to buckling that can occur with conventional tubing hanger applications. Tension tubing hangers utilize an MRS metal seal between the hanger neck and adapter to isolate the production flow. A continuous control line feature is standard with the Tension tubing hanger system that allows the control line to exit through the adapter and be sealed in a specially designed exit block. The Tension tubing head and hanger system is available in applications up to 20,000 psi and all API trim levels.
