Our API 16A hydril annular BOP can be used in work over and drilling operations equipped with hydril control systems. The BOPs are designed and manufactured in full conformity to 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.It can seal the drilling tool or well bore efficiently, preventing oil well blow outs. Its anti H2S performance conforms to the NACE MR 0175 standard.
