Conventional Tubing Head

The Tubing Head is the uppermost spool in a wellhead assembly. It provides a means to support and seal a tubing string. The upper section has a straight type bowl and a 45 degree load shoulder to support and seal the tubing string by means of a tubing hanger. There is a full set of lock-screws to safely secure the tubing hanger in the head. The lower section houses a secondary seal to isolate the production casing string and provide a means to test the wellhead seals. Threaded or weld-on tubing heads attach directly to the production casing.
