The SM-T tubing hanger uses a metal taper design on the hanger’s neck to isolate the production flow. Metal seals are far superior to elastomers making this hanger suitable for more critical service applications.

During installation, the hanger is landed and the lockscrews run in to retain the hanger and energize the annulus seal. The metal seal on the hanger neck is energized by making up the adapter. The taper on the ID of the adapter slightly opposes the OD of the tubing hanger neck,

causing the neck to deform slightly. This deformation is safely within the elastic limits of the yield strength of the hanger material, permitting the connection to be broken and remade repeatedly without damaging the sealing surfaces.

An internal profile is provided for setting a back pressure valve.
