3-1/16" 10M x 3" Fig 1502 Female Thread Flange Adapter – Oil & Gas Flowline Fitting

The Extreme-Pressure Flange Adapter, 3-1/16" 10M x 3" Fig 1502 Female Thread, is engineered to provide a robust, leak-free crossover connection between high-pressure API 6A flanged assets and high-capacity 3-inch hammer union flowlines. Designed for the most demanding upstream oilfield operations, this specialized crossover adapter allows operators to safely and seamlessly transition from a 3-1/16" 10,000 PSI (10M) flanged connection to a 3" Figure 1502 female union interface.

Constructed from premium high-integrity forged alloy steel, this crossover easily withstands the severe and abrasive field environments typical of high-volume well testing, heavy frac support, and extreme-pressure flow-back procedures. The flanged end conforms strictly to API 6A dimensional and material requirements for a 3-1/16" bore, while the precision-machined 3-inch 1502 female threaded end ensures optimal thread engagement, heavy-duty vibration resistance, and superior seal integrity under massive pressure and high-volume fluid loads.

Serving as a critical pressure-control link, this 10M flange adapter optimizes layout flexibility, smoothly bridging connections across heavy-duty manifold setups and extreme-pressure flowline configurations without compromising structural safety.

Features & Benefits

• Seamless System Integration: Safely bridges a 3-1/16" 10,000 PSI API flange with a standard 3" Figure 1502 Female Hammer Union end for versatile, high-capacity piping transitions.

• 10,000 PSI Rating (10M): Engineered to safely contain extreme high-pressure upstream environments, perfectly matching the 10,000 PSI rating of the flanged end.

• Forged Alloy Steel Construction: Built to handle abrasive drilling and frac fluids, high-velocity flows, and severe oilfield handling without compromising structural integrity.

• Precision-Machined Threads: Ensures reliable makeup and smooth, secure engagement with corresponding 3-inch male union components.

• Heavy-Duty Reliability: Maximizes structural strength in high-vibration systems and accommodates the increased flow rates required in heavy-duty pumping operations.

• Service Reliability: Manufactured to meet rigorous quality, dimensional, and material verification standards for standard oilfield service.

Specifications & Technical Details

Applications

This 10M flange to 3-inch 1502 female thread hammer union adapter is essential for extreme high-pressure upstream operations requiring flexible structural crossovers and high-capacity fluid transfer. Typical applications include transitioning flow from wellhead tree components, high-pressure surface well testing flowlines, severe service flow-back piping, choke and kill lines, and interfacing 3-1/16" 10M flanged valve assemblies with standard 3-inch 1502 temporary pipework.

Quality Assurance

Each crossover adapter undergoes strict quality inspection protocols, including dimensional checks, precise thread gauging, and material traceability verification (MTRs) to ensure reliable and repeatable pressure containment in the harshest operational conditions.
