Product Description

ANNULAR BOP

Our 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.

Features & Benefits of Annular BOPs

• Steel inserts prevent extrusions of the rubber and feed inward to close on any pipe or tubular in the wellbore.
• Replaceable bearings are used in the operating system to prevent metal contact of moving parts.
• Adapter ring located below the upper housing prevents contamination of the operating system during packing element replacement.
• Wedged cover upper bearing is also available.
• Available in all standard bore pressure ratings
• Special rubber materials available for non-standard environments.

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.
