Rotary BOPThe rotary blowout preventer (BOP) is used in balanced drilling, negative pressure (underbalance) drilling, counter circulation drilling and well drilling operation by using air, natural gas or foam as circulating medium as well as well servicing operation. The self-sealing rubber sealing element can ensure that the rotary workover operation or the tripping in/out the pipe string operation with pressure borne is made under maximum kinetic pressure conditions.
