Casing Head Assembly Working Pressure 2000 ~ 20000 psi Connected Casing O.D. 7-5/8 ~ 13-3/8 in
Descriptions of Casing Head Assembly Working Pressure 2000 ~ 20000 psi Connected Casing O.D. 7-5/8 ~ 13-3/8 in :
Casing Head is adapter connecting the surface casing string and either the BOP stack or the wellhead. It is either threaded, welded or slip lock to the casing, and may have a flanged or clamped connection to match the BOP stack or wellhead., the casing head is typically qualified to withstand up to 10,000 psi working pressure. It suspends the casing and packs off the next casing string while providing annular outlets, as well as supporting the BOP while drilling the remaining stages. The straight bowl design prevents the wedge locking of bowl protectors, casing hangers, and test plugs, simplifying the installation process.
