Product Description
21 1/4\" 2000psi Cone Annular BOP Packing Element
High-performance annular blowout preventer packing element designed for 21 1/4\" bore size with 2000 psi working pressure rating. Engineered for reliable well control operations in demanding drilling environments.
Key Features & Technical Advantages
Spherical Rubber Design
Half-sphere configuration with radial supporting ribs made of alloy steel segments embedded in durable rubber compound.
- Non-Blocking Operation: Steel ribs retract from bore when open, preventing hole blockage even with significant rubber wear
- Turn-Over Protection: Steel segments resist pressure-induced rubber turn-over, maintaining structural integrity under high pressure
- Funnel Effect: Optimized compression pattern facilitates smooth tool joint entry during tripping operations
- Extended Service Life: Substantial rubber reserve allows for multiple tripping operations without element replacement
- Pressure-Assisted Sealing: Well pressure enhances sealing capability for reliable blowout prevention
- Reduced Friction: Metal-to-metal contact between steel segments and housing provides lower coefficient of friction than rubber-to-metal
