Premium API 16A Blowout Preventer (Annular or Ram type) certified for 5,000-10,000 psi service, suitable for both drilling and workover operations.
Annular BOP shall be equipped with hydraulic control system. It is usually used with ram BOP and also independently.
It can be used for following operation:it can seal various shape or size of the square pipe,drill rod subs, drill collar, casing and cable etc. When there is no drilling tool in hole, it can seal the wellhead completely. Under the control of hydraulic control system which is equipped with a depressuring pressure regulating valve or a cushion accumulator, it can force stripping with 18° tool joint
