Safety and Reliable API Standard Rotating/rotational BOP for Oil Drilling Well Control
API standard rotating/rotational BOP
Usage and application
Always be positioned at the top of the stack above annular or ram preventer. It is used to seal rotating drill pipes and pass flow. Be assembled with hydraulic BOP, drill pipe check valve, gas seperator and u kill well trip pressurization device, it can finish drilling and unkill well drilling safely. The rotating BOP play important role in releasing low pressure oil gas zone, leak preventive drilling, Pneumatic drilling, unkill drilling and other special operation.
