Bop Equipment Annular Bop
ANNULAR BOPOur annular BOPs are designed and manufactured to API Spec 16A standard. Featuring a spherical or tapered packing element our they have a substantial significant volume, low operating pressures and excellent sealing.
Spherical or tapered packing element offers significant storage volume, low operating pressure and excellent sealing.
Bonnet is hemispherical-shaped so there is no stress concentration whenever bearing pressure. Pressure is evenly distributed; convenient for disassembly and assembly (except FHZ5414).
Low position of piston gives a shorter moving distance and less ring wear.
Lip type seal rings means longer service life.

Feature
Rubber core store glue big quantity , small friction resistance, when switch pressure sealing ability.
Using hemispherical head, no stress concentration phenomenon when under pressure, casing stress evenly, easy to tear open outfit.
Piston stroke is short, low height, and set the wear ring.
The lip seal, long service life.
Low temperature processing annular blowout preventer shell diameter has a trough steam pipe, pipe ventilation with saturated vapor, round shell for heating.( For the customer to choose ).
High sulfate-resistant blowout preventer internal all parts contact well liquid surfacing high nickel base alloy, can achieve the highest levels of resistance to effect such as H2S and CO2. For the customer to choose.
