2-9/16" 5M x 3" Fig 1502 Female Thread Flange Adapter – Oil & Gas Flowline Fitting

The High-Pressure Flange Adapter, 2-9/16" 5M x 3" Fig 1502 Female Thread, is engineered to provide a reliable, leak-free crossover connection between larger API 6A flanged assets and high-volume 3-inch hammer union flowlines. Designed for demanding upstream oilfield operations, this specialized crossover allows operators to safely and seamlessly transition from a 2-9/16" 5,000 PSI (5M) flanged connection to a larger 3" Figure 1502 female union interface.

Built from high-integrity forged alloy steel, this size-adapting crossover easily withstands the harsh field environments typical of high-volume production, heavy well testing, and severe flow-back procedures. The flanged end meets stringent API 6A dimensional and material specifications, while the precision-machined 3-inch 1502 female threaded end ensures optimal connection alignment, vibration resistance, and superior seal integrity under massive pressure and fluid volume loads.

Serving as a critical pressure-control link, this 5M flange adapter optimizes layout flexibility, allowing for safe structural step-ups in pipe size across heavy-duty manifold setups and high-capacity flowline configurations.

Features & Benefits

• Seamless Size Integration: Bridges a 2-9/16" 5,000 PSI flange with a larger 3" Figure 1502 Female Hammer Union end for versatile, high-volume piping transitions.

• 5,000 PSI Rating (5M): Engineered to safely contain high-pressure upstream environments, perfectly matched to the 5M rating of the flanged end.

• Forged Alloy Steel Construction: Built to handle abrasive drilling fluids, high-velocity flows, and rugged 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 increased flow rates.

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

Specifications & Technical Details

Applications

This 5M flange to 3-inch 1502 female thread hammer union adapter is ideal for high-pressure upstream operations requiring flexible structural crossovers and increased flow capacities. Typical applications include high-rate surface well testing manifolds, temporary high-volume flow-back piping, choke and kill lines, and interfacing 2-9/16" 5M flanged wellhead valving with larger 3-inch 1502 iron configurations.

Quality Assurance

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