The casing head, a component connecting the casing to the wellhead assembly of various types and sizes, is used to support the weight of both the intermediate(protective) string and the production string, and to seal up the annular space between the casings, thus providing a crossover connection for the installation of the BOP, the tubing head, the Christmas tree and other top wellhead components. It is also used to inject additional cement slurry or balance fluid, monitor the sink, and execute other operations through both of the two bypass holes in the casing head body.
The HENGXIN casing head, which is of standsard structure, is fitted with a complete set of casing head hangers manufactured by HENGXIN, which are available for choice according to different requirements of casing procedure and wellhead conditions. The top part of body is API6B or API6BX flanged.
