Casing head is a kind of part of connecting casings and wellheads. It is used to support the weight of technical casing and intermediate casing and seal the annular space between the casings, which provides a transition joint for the installation of the tubing head, Christmas tree and other wellheads. The two-side-outlet design allows the casing head to supply cement, monitor and control well's sinking, and inject balance liquids etc.
Boban casing head spools are provided with a seat for secondary sealing. The lower flange can be provided with a second smaller supplementary ring gasket allowing the maximum pressure build-off with one stage. The flanges and the passing inside diameters are designed according to API spec.6A. We also design into common type and integral type according to customer's requests.
