Complete Wellhead For Single completion 9 5/8”x5 1/2”x 2 7/8” x 5000psi
In oil drilling, a casing head is the indispensable components used for connecting casing to wellhead assembly, which is a simple metal flange welded or screwed onto the top of the conductor pipe or the casing and forms part of the wellhead system for the well. The casing head can support intermediate string and production string, sealing the annular space between the casings. It is the primary interface for the surface pressure control equipment, such as the blowout preventers or the Christmas tree. The wellhead casing head is designed and manufactured according to API 6A specification.
