Nominal Bore Size:
• Designed to seal a wellbore of approximately 13 5/8 inches.
Working Pressure:
• Rated for a maximum working pressure of 5000 PSI (approximately 345 bar).
Seal Type & Material:
• Uses an elastomer-based annular seal (often formulated with high-performance materials like Viton or nitrile) designed to conform around the drill pipe or casing.
• The seal is engineered for repeated cycling and exposure to drilling fluids.
Body Construction:
• Constructed from high‑strength, forged or cast alloy steel to ensure structural integrity under pressure and harsh operating conditions. • Typically includes a robust, machined body with integrated hydraulic ports for actuation.
Actuation & Operation:
• Hydraulic actuation is standard, allowing the annular to rapidly engage and form a tight seal.
• Designed for ease of operation in well control situations, with features to facilitate rapid opening and closing.
Installation & Integration:
• Engineered with standard mounting interfaces so it can be integrated into a BOP stack or well control system. • Includes connection details (thread sizes, bolt patterns, etc.) that are specified in the manufacturer’s datasheet.
Dimensions & Weight:
• Overall dimensions (such as body height and outer diameter) and weight will depend on the specific design, but these units typically weigh several hundred pounds and are built to fit within standardized BOP assemblies.
