The Tubing Head is the top spool on a surface wellhead assembly. It is
installed after the last hanger or production casing/tubing annulus seal.
When the well is completed, the tree is installed on top of the tubing head
with a tubing head adapter.
Tubing heads are provided with a straight bore bowl design to accommodate
the outer profile of a tubing hanger. Tubing hangers come in single or dual
forms for single and multiple completions in working through various pressure
ratings and sizes to meet all single or multiple completion requirements.
If conversion from existing single completion to multiple completions should
be required, a TC attachment can be installed on top of any existing head
