Annular BOP
Annular BOP is an important part of the well control devices. It is mainly used to control the wellhead pressure in the drilling, well work over and oil testing, effectively preventing from the blowout accidents and working in safety.
Annular BOP
- Working Pressure: 2000psi ~ 20000psi
- Nominal Bore Diameter: 7 1/16″ ~ 30″
- Temperature Ratings for Metallic Materials: T75, T20, TO
- Temperature Ratings for Non-metallic Sealing Materials: A ~ D (-26℃ ~ +121℃)
- Working Medium: petroleum, natural gas, mud, gas containing H2S or CO2
Annular BOP can only be used when equipped with BOP hydraulic control device. It is usually used with ram BOP or separately. Sealing element has spherical and conical type.
