Casing Head

The casing head, installed at the bottom of wellhead assembly connecting casings and various wellhead assemblies, is composed of a body, casing hanger and seal assembly. The casing head is used for supporting the weight of technical and production casing, sealing the annual space between the casing and providing a filtered connection for the installation of upper wellhead assemblies. These assemblies include a blowout preventer (BOP), tubing head and christmas tree. The surface casing is connected by a flange located below the casing head. The oil-string casing is connected by a screw thread inside of the casing head.
