DEENPU ISA Spherical Annular BOP — Overview
DEENPU ISA Spherical Annular Blowout Preventer is a hydraulic-operated well control device designed for workover and drilling operations. The spherical design consists of just five major components: Upper Housing, Lower Housing, Adapter Ring, Piston, and Packing Element — providing simplicity, ease of maintenance, and field-proven reliability.
Available in bore sizes from 7-1/16 inch to 21-1/4 inch with pressure ratings from 2,000 PSI to 5,000 PSI (10,000 PSI bottom flange options). All units are manufactured to API 16A Monogram standards with ASTM A487 GR4D cast steel housings.
Key Features & Benefits
- Only 5 major components — spherical design simplifies maintenance and reduces spare parts inventory
- Requires only two hydraulic connections (Open/Close) for operation
- Self-centering packing element — no manual adjustment needed after closing
- Seals on multiple pipe sizes, hexagonal kelly, and open hole
- Bolted cover design for easy packing element replacement
- I-Filter seal option available for enhanced contamination protection
- Wear bands on all dynamic sealing surfaces extend service life
- Full traceability — all components serialized and documented
