SB Type Annular BOP

Parameters

The SB Type Annular Blowout Preventer (BOP) is engineered to deliver uncompromising well control and reliable pressure containment during demanding drilling operations. Designed to form a pressure-tight seal around virtually any shape in the wellbore—including drill pipe, casing, wireline, or even an open hole—this equipment acts as a critical safeguard against uncontrolled formation fluid kicks. The technical parameters outlined below demonstrate the equipment's capacity to withstand extreme wellbore pressures while maintaining structural integrity. Every unit is rigorously tested to meet the exact specifications required for safe field deployment, ensuring that operators can maintain complete control over the wellbore environment. The precision-machined connections and optimized hydraulic fluid requirements ensure rapid response times when securing the wellhead.

Reference to Standards

Ensuring operational safety in highly demanding environments requires strict adherence to global manufacturing protocols. Our SB-Type Annular BOP is meticulously fabricated and certified in accordance with the most stringent industry standards, guaranteeing reliable performance under extreme stress. By aligning with these internationally recognized frameworks, we provide drilling operators with the assurance that our well control systems possess the necessary metallurgical properties, pressure containment capabilities, and mechanical resilience. These certifications reflect our commitment to delivering equipment that withstands the harsh realities of modern oil and gas extraction, including exposure to corrosive fluids and high-pressure differentials. The following reference table outlines the specific API and NACE standards that govern our engineering and quality assurance processes.

Specifications of the SB-type BOP we can provide

Our manufacturing facility produces a comprehensive range of bore sizes and pressure ratings to accommodate diverse drilling programs and wellhead configurations. Selecting the appropriate blowout preventer specification is critical for maintaining wellbore stability and ensuring compatibility with existing rig infrastructure. The SB-Type BOP is available in multiple configurations, ranging from compact 7-1/16" models for specialized interventions to massive 13-5/8" units designed for deepwater or high-pressure exploration. Each variant maintains the same proven spherical packing element design, ensuring consistent sealing performance regardless of the physical dimensions.
