Annular blowout preventer consists of body, upper housing, sealing element, dust-proof ring, and piston. It provides a rugged, reliable preventer and ease of service and widely used Offshore (subsea and surface) and onshore.
Annular blowout preventer is compact, seal any size kellys, drill pipe, tool joints, drill collars, casing or wireline. Sphericals also provide positive pressure control for stripping drill pipe into and out of the hole.
Annular blowout preventer is Manufactured in accordance with API Specification 16A, and NACE MR0175 per API Specification 16A, Temperature T20, Standard nitrile packing element: 40°F to 170°F.
1. Rubber core store glue big quantity, small friction resistance, when switch pressure sealing ability.
2. Using hemispherical head, no stress concentration phenomenon when under pressure, casing stress evenly, easy to tear open outfit.
3. Piston stroke is short, low height, and set the wear ring.
4. long-life sealing element provides positive seal after hundreds of tests to full working pressure
5. Strong, simple construction- only five major parts, which simplifies maintenance.
6. Sealing element design provides long stripping life
7. 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.
