The casing head is a kind of part of connecting casings and wellheads. It 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 are sinking, and inject balance liquids, etc.

In oil drilling, a casing head is a simple metal flange welded or screwed onto the top of the conductor pipe (also known as drive-pipe) or the casing and forms part of the wellhead system for the well.
This is the primary interface for the surface pressure control equipment, for example blowout preventers (for well drilling) or the Christmas tree (for well production).
The casing head, when installed, is typically tested to very strict pressure and leak-off parameters to insure viability under blowout conditions, before any surface equipment is installed.
Features:
1. Designed and manufactured according to API spec 6A.
2. Accepts a wide variety of slip and mandrel casing hangers.
3. Three different types of outlets: Line pipe, Flanged (Studded) Extended flanged outlets.
4. Multiple bottom connections, such as: Slip-on weld, Slip-on weld with O-ring, Threaded and Sure Lock.
5. Lockdown screws in the top flange.
