Abstract
A hanger assembly has at least one elongated channel disposed on the outer surface of the hanger assembly. An alignment/anti-rotation tab member is moveably disposed within each elongated channel and can selectively alternate between a first retracted configuration and a second extended configuration. In the second extended configuration, each alignment/anti-rotation tab member can be received within a mating channel along the inner surface of the central through bore of the wellhead. Each extended alignment/anti-rotation tab member can engage against a mating recess or channel in order to align and orient the hanger assembly within the central through bore of the wellhead (permitting orientation and alignment of ports in the hanger assembly and the surrounding wellhead), while also preventing rotation of the hanger assembly relative to the wellhead.
