Annular Blowout Preventer with Spherical Rubber
An annular BOP with spherical rubber is a type of blowout preventer for oil and gas drilling as well as mining and other industries. The BOP works mainly to stop any liquid from surfacing in a dangerous explosion to create a safe working environment. Your consulting is welcomed at any time if you need to know more about our blowout preventers.
Features
- The annular BOP can divert the spraying of oil and gas and limit the spraying area to minimize risks of potential accidents.
- The annular BOP’s spherical rubber features high strength and flexibility and thus is wear-resistant and anticorrosive, ensuring long-term reliable operation in tough conditions.
- Different sizes of annular BOPs are available and can be selected for diverse applications.
- The blowout preventer can be installed directly on existing pipe systems.
