Annular BOP
Annular Blowout Preventer with Spherical Rubber 
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. Technical Parameters
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.
