Annular BOP
- Rubber core store glues 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.
- Long-life sealing element provides positive seal after hundreds of tests to full working pressure.
- Strong, simple construction- only five major parts, which simplifies maintenance.
- Sealing element design provides long stripping life.
