What is annular bop
The main feature of the Annular Blowout Preventer is its capability to close and seal on almost any size tools in drill pipe, tool joints, drill collars within most of its range. Annular Blowout Preventer is a large valve used to control wellbore fluids, usually installed above the ram preventers that forms a seal in the annular space between the pipe and wellbore. In this type of valve, the sealing element is similar to large rubber doughnut that is squeezed inside to seal on drill pipe.
Annular Blowout Preventer vs RAM Blowout Preventer
The annular blowout preventer performs several functions in drilling operations. It seals the annular space between the tubing, casing, and drill pipes. It also helps maintain the seal when the casing, tubing, or drill pipes are out of the drill hole. Unlike RAM blowout preventers, annular BOPs can seal various pipes of different sizes.
What is an annular blowout preventer? When asked that question, you’ll have the answer. If you have a drilling project, consider getting a blowout preventer from a reputable company like BOP Products. We offer high-quality products and services to ensure the safety of workers.
