13 5/8 Inch Shaffer Annular Bop Preventer 3000psi For Wellhead
Wellhead Annular Preventer Bop 13 5/8"-3000psi
Annular Preventer Bop is shut in the well for oil testing, workover, well completion and operating process to prevent the blowout accident, totally enclosed and semi-closed two functions into one, Annular Preventer Bop has a simple structure, easy to operate, resistant to high-pressure characteristics is used to prevent blowouts safety oilfield sealing wellhead.
How the annular BOP work
Close – When the hydraulic oil is pumped into the extended port, the element inside will be lifted and squeezed into the pipe/tubular.
Open – On the other hand, if the hydraulic fluid is pumped into the retract port, the element will be pushed down resulting in releasing the tubular.
Annular vs RAM BOP
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.
