11 Inch Well Drilling Annular Blowout Preventer 105mpa 10000 Psi
Annular Blowout Preventer can be used in workover and drilling operations equipped with hydraulic control systems. The BOPs are designed and manufactured in full conformity with the API 16A standard. The annular BOP mainly consists of a body, a header, a rubber core, and a piston. The inner rubber core is interchangeable. While the annular BOP can be used independently, it normally works with a single or a double BOP.
