Our API 16A hydril annular BOP (blowout preventer) 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.

Key Feature

1.Annular BOP can fully seal the wellhead when there is no string inside the wellbore.

2.Annular BOP can seal the annulus space of the wellhead when there is a string, wire line and cable inside the wellbore.

3.Snubbing can be performed if the butt welding drill pipe has an 18°beve.

4.Equipped with an energy accumulator, and a tubing coupling can pass through the annular BOP under pressure when well pressure is less than 3Mpa.
