Equipment attached to the casing spool used to hang the tubing (smallest casing string) and seal the annulus between the tubing and casing.
The top spool on a wellhead assembly contains the highest pressure in the wellhead, and contains a load shoulder to hang the tubing hanger and tubing string. When the well is completed, the tree is installed on top of the head with a tubing head adapter. Providing a means to support and test the BOPs while completing the well, the tubing head is a necessary component when drilling and completing a well. The standard tubing head product line combines a straight- bore profile with a varied number of aligning pins, depending on the chosen model. FMC’s tubing heads eliminate the “wedge-locking” of the bowl protector, BOP test plugs, and tubing hangers. As additional advantages, valve removal (VR) threads are standard on all flanged or studded tubing head outlets, and if a 9” or larger top flange is required, the C-29 casing hanger can be used for casing-type completions.
