Hydril GK Type 13 5/8"-5000psi Forging Annular BOP

The Hydril Annular Blowout Preventer (BOP) is a versatile pressure control system engineered for surface rigs, offshore platforms, and subsea operations. With a proven track record in the petroleum industry, it delivers reliable well control with customizable features and operational efficiency.

Key Features & Benefits

Simplified Design: Only two primary components (piston and packing element) minimize wear points, reducing maintenance requirements and operational downtime
Stable Long-Piston Configuration: Features a length-to-diameter ratio of nearly 1:1, preventing cocking and binding during operations with off-center drill pipe or uneven sediment accumulation
Conical Bowl Piston Design: Serves as a sealing surface against rubber packing elements, eliminating metal-to-metal contact and extending service life
Field-Replaceable Wear Plate: Provides an upper non-sealing wear surface for packing elements, enabling rapid on-site maintenance and cost-effective repairs
Dual Head Configuration Options: Screwed head design ensures secure body-head connection without loose components; latched head (available for 13-5/8"-5000 psi and larger models) facilitates quick access to packing elements and seals
Robust Sealing System: Large pressure-energized seals dynamically seal piston chambers, ensuring extended seal longevity and minimal maintenance
Comprehensive Testing & Compliance: Operating chambers tested to full working pressure; meets NACE MR-01-75 standards for sulfide stress cracking resistance
Flexible Packing Element Selection: Two rubber compound options (natural rubber and nitrile rubber) accommodate diverse drilling conditions

Operational Principles

Basic Actuation: Requires both opening and closing hydraulic pressure. Seal-off is achieved by applying hydraulic pressure to the closing chamber, raising the piston and forcing the packing element into sealing engagement with drill pipes or open bore.

Well Pressure Assistance: After initial seal establishment, well pressure helps maintain the seal (excluding 7-1/16"-15,000 and 20,000 psi models requiring sustained closing pressure).

Stripping Operations: Drill pipe can be rotated and tool joints stripped through closed packing elements while maintaining seal integrity. Optimal packing element life is achieved by setting closing chamber pressure to permit minimal drilling fluid leakage for lubrication.

Control System Integration: Compatible with standard accumulator units equipped with separate pressure regulator valves for annular BOP operation and sufficient accumulator volume.

Supplementary Components: For slow-responding pressure regulator valves, install an accumulator (surge absorber) precharged to 50% of required closing pressure in the closing chamber control line. Subsea operations may require additional accumulators in opening chamber lines to prevent pressure fluctuations.
