Product detail:
The casing head is a kind of part connecting casings and wellheads.
It is used as supporting the weight of technical casing and
production casing, sealing the annular space between the casings,
and installing BOP stacks. It provides a transition joint for the
tubing head, Christmas tree and other wellheads. It can also supply
cement, monitor & control well s sinking, and inject balance
liquids etc by the two side outlets on the casing head housing. The
casing head manufactured by our company is a standard structure,
the casing hanger produced fits well with the casing housing, and
the casing hanger of different sizes are available according to the
casing procedure and the change of well head conditions.
The standard casing head s top connection is API 6B or API 6BX
flange.
