Oil & Gas Well API 6A Casing Head Casing Hanger For Wellhead Equipment
The casing head is a kind of part of wellhead equipment assembly to connect casings and other wellheads parts. The casing head is used to support the weight of technical casing and intermediate casing and seal the annular space between the casings, which provides a transition joint for the installation of the tubing head, Christmas tree and other wellheads. The two-side-outlet design allows the casing head to supply cement, monitor and control well's sinking, and inject balance liquids etc.
