2-1/16" 15M API 6A Blind Flange – Oil & Gas Flowline Fitting

The 2-1/16" 15M Blind Flange is an ultra-high-pressure isolation component engineered to securely seal and terminate flowlines, manifold assemblies, and wellhead systems in the most demanding upstream oil and gas operations. Rated for an extreme cold working pressure of 15,000 PSI (15M), this solid flange effectively blanks off open connections, preventing fluid bypass and ensuring absolute pressure containment during critical operational shutdowns, testing, or maintenance phases.

Manufactured from premium high-strength forged alloy steel in strict accordance with API 6A standards, this blind flange is built to withstand the severe stresses of extreme-pressure upstream environments, including frac support and choke & kill operations. Its robust, non-bored face provides maximum structural integrity against abrasive drilling muds, hydrocarbons, and high-velocity fluids, ensuring long-term durability and safety in the field.

Whether utilized for capping wellheads or isolating sections of an extreme-pressure manifold, the 2-1/16" 15M Blind Flange delivers a dependable, field-proven solution for absolute flow termination where uncompromising safety is required.

Features & Benefits

• Absolute Flow Isolation: Solid, unbored design securely terminates extreme-pressure piping systems and prevents any fluid bypass.

• 15,000 PSI Rating (15M): Engineered to safely contain ultra-high-pressure upstream environments.

• API 6A Compliant: Manufactured to recognized industry standards to ensure universal compatibility and rigorous safety.

• Forged Alloy Steel Construction: Provides exceptional durability and resistance against extreme pressure stresses, abrasive fluids, and harsh weather conditions.

• Versatile Utility: Essential for safely blanking off unused manifold ports, capping wellheads, or isolating pipelines during high-pressure testing.

• Dependable Sealing Face: Precision-machined ring groove ensures a perfect, leak-free seal with standard API ring joint gaskets under extreme conditions.

Specifications & Technical Details

Applications
