Our Company Launches New 18-3/4" 10,000psi High-Pressure, Large-Bore, High-Temperature Blowout Preventer Stack For Offshore Drilling

Our company today announces the release of a new blowout preventer (BOP) stack for offshore platform drilling: the 18-3/4" 10,000 psi BOP stack. Designed with the three technical highlights of high pressure, large nominal bore, and high-temperature capability, this product is engineered for deep wells, high-pressure high-temperature (HPHT) conditions, and complex offshore operating environments to further enhance well control safety and operational efficiency.

Product Highlights

High pressure rating: Engineered and manufactured to meet 10,000 psi working/test requirements, suitable for ultra-high-pressure well control scenarios.  

Large nominal bore: 18-3/4" nominal bore significantly increases flow capacity, facilitating mud and well-fluid circulation, well-control operations, and well access tasks.  

High-temperature capability: Material selection and heat-treatment optimizations deliver long-term stability at elevated temperatures, suitable for high-temperature influxes and demanding offshore conditions.

Key Technical and Performance Advantages

Robust structural strength: High-strength alloy materials and advanced heat treatment ensure structural integrity and fatigue life under extreme pressure/temperature conditions.  

Optimized sealing system: Multi-stage sealing design and high-temperature-resistant sealing materials effectively minimize leakage risk and extend maintenance intervals.  

Easy maintenance and repair: Modular design allows straightforward onsite replacement of seats and wear parts, reducing downtime and maintenance costs.  

Compatibility and integrability: Seamless interface with common BOP control systems, choke manifolds, valves, and other well-control components; supports customer-specific configurations.  

Strict testing and warranty: Complete functional testing and pressure tests are performed before shipment, with detailed inspection reports and quality assurance documentation provided.

Applications

Offshore platform drilling operations, particularly suitable for HPHT wells and scenarios requiring large-bore flow capacity for well control; also adaptable for integration with standard and specialized wellhead systems.

Company Statement

"Our 18-3/4" 10,000 psi BOP stack represents a significant advancement built on years of BOP development and international field-service experience," said the company’s General Manager. "As offshore deep-well and HPHT drilling demands grow, we remain committed to safety-first, reliability-driven solutions that meet the most demanding operating conditions.
