TYPE BC-22 CASING HEADS

Benoston’s BC-22 is a straightborecasing head that accepts any of two heavy duty interchangeable hangers. Each of these hangers (BC-21 and BC-22) can support weight beyond the joint strength of the pipe itself, with mini- mum casing deflection. Both can be lowered through blowoutpreventers. The BC-22’s straight boreprevents test plugs from wedging whenpressure is applied, reduces maintenance costs,available in workingpressures up to 10,000 psi. All casing head spools will accept bit guides and secondary seals if desired. When using bowl protector in BC-22 casing heads, we use 2 lock screws in upper flange (BC-2BP) or a hold down flange with lock screws can be furnished.
