476.3mm 18 3/4" Annular Preventer Bop Hydril For Oil And Gas

Annular Preventer Bop Hydril is manipulated by the hydraulic control system. When it is shut off, high-pressure oil flows into piston's underside closed cavity through the oil port in the central shell, to push piston upwards, and the conical surface of piston squeezes rubber core. Due to the restrictions of head cover, rubber core can’t go upwards but is pushed towards the center of wellhead until it encloses drilling tool or enclose wellhead totally to shut the well.
