API 16A Standard FZ35-70 Single Ram Bop/Double Ram BOP/BOP Blowout Preventer Stack

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Wellbore Sealing & Pressure Control: Designed to seal the wellbore and manage high-pressure environments in drilling operations, preventing blowouts through robust alloy steel construction and forged components.
  • Pipe Sealing/Cutting: Equipped with Single or Double Ram configurations to seal around drill pipes or fully shear through them in emergencies, ensuring operational safety.

Key features

  • 1. Forged Alloy Steel Construction for Extreme Durability

    • With forged alloy steel material, withstand harsh drilling environments and maintain structural integrity under extreme pressures and temperatures. This robust design offers ~25% greater strength than cast alternatives*, ensuring long-term reliability in oil and gas operations.

  • 2. Flange-Mounted Design for Seamless Integration

    • With a flange-mounted configuration, easily integrate into existing drilling rig systems for rapid setup and alignment. This design reduces installation time and ensures compatibility with standard industrial equipment.

  • 3. API 16A Compliance for High-Pressure Reliability

    • With API 16A certification, handle pressures up to 10,000 psi—~30% higher than non-compliant models*. This certification guarantees adherence to rigorous industry safety and performance standards for oilfield applications.

  • 4. Single/Double Ram Mechanism for Blowout Prevention

    • With a robust single or double ram design, effectively seal and control well pressure to prevent catastrophic blowouts in critical drilling scenarios. This feature ensures operator safety and protects against equipment failure.

  • 5. Multi-Bolt Sealing System for Leak-Free Performance

    • With a precision-engineered multi-bolt sealing mechanism, maintain tight seals even under fluctuating high pressures. This design reduces leakage risks and enhances operational efficiency compared to conventional sealing methods.

Supplier's note

  1. Technical Breakthroughs:

    • Forged Alloy Steel: Enhances tensile strength by 20% compared to cast steel, resisting deformation under extreme pressures.
    • Dual Ram Design: Offers 30% faster seal activation than single-ram systems, minimizing well control delays.
    • Corrosion-Resistant Seals: Triple the industry-standard chemical resistance, ensuring longevity in acidic or saline environments.

  2. Version Selection Guide:

    • Base Model: Ideal for standard drilling operations (≤5,000 psi) where cost-efficiency is prioritized.
    • Advanced Model: Suited for offshore drilling (up to 7,250 psi) requiring enhanced durability and faster response times.
    • Pro Model: Designed for ultra-deep wells (10,000 psi) and corrosive fluids, pairing its 800 MPa material strength with 15,000-cycle seals for mission-critical safety.

With the Pro Model’s triple chemical resistance, you can safely handle corrosive fluids like sour gas. Its forged alloy steel construction ensures 20% higher pressure tolerance than traditional cast models, making it the gold standard for extreme drilling scenarios.
