3-1/16" 15M x 3" Fig 1502 Male Wing Flange Adapter – Oil & Gas Flowline Fitting

The Ultra-High-Pressure Flange Adapter, 3-1/16" 15M x 3" Fig 1502 Male Wing, is a specialized extreme-duty crossover component engineered to provide a rapid, ultra-secure connection between massive API 6A flanged equipment and high-capacity 3-inch hammer union flowlines. Designed for the most demanding and rigorous upstream oilfield operations, this crossover adapter allows operators to safely and seamlessly transition from a 3-1/16" 15,000 PSI (15M) flanged connection to a 3" Figure 1502 hammer union interface. The integrated 3-inch male wing nut ensures fast makeup in the field without the need for specialized tooling, critically reducing rig-up times for ultra-high-pressure fluid transfer and massive frac operations.

Manufactured from heavy-duty high-integrity forged alloy steel, this crossover adapter is built to endure the harsh, highly abrasive environments typical of severe well testing, high-rate frac support, and extreme-pressure flow-back. The flanged end conforms strictly to industry dimensional and material standards for a 3-1/16" bore, while the precision-machined 3-inch 1502 male end with its robust wing nut guarantees a highly vibration-resistant, leak-free seal under massive operational 15,000 PSI pressure and high-volume fluid loads.

Serving as a vital pressure-control link, this male wing flange adapter optimizes layout flexibility, smoothly bridging connections across heavy-duty manifold setups and temporary flowline configurations without compromising structural safety or flow capacity.

Features & Benefits

• Rapid Makeup Design: Features an integrated 3" Figure 1502 Male Wing Nut for quick, ultra-secure hammer union connections in the field.

• Seamless System Integration: Safely bridges a 3-1/16" 15,000 PSI API flange with a standard 3" Figure 1502 temporary iron configuration for versatile, high-capacity piping transitions.

• 15,000 PSI Rating (15M): Engineered to safely contain ultra-high-pressure upstream environments, perfectly matching the 15,000 PSI rating of the flanged end and the 1502 union.

• Forged Alloy Steel Construction: Delivers exceptional durability against abrasive frac fluids, high-velocity flows, and severe field handling.

• Vibration-Resistant Sealing: Ensures reliable connection alignment and optimal sealing integrity in high-vibration, high-capacity pumping systems.

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

Specifications & Technical Details

Applications

This 15M flange to 3-inch 1502 male wing hammer union adapter is essential for ultra-high-pressure upstream operations requiring flexible structural crossovers, fast rig-up times, and high-capacity fluid transfer. Typical applications include transitioning flow from heavy-duty wellhead tree components, integrating high-rate surface well testing flowlines, severe service flow-back piping, heavy-duty frac manifolds, and efficiently interfacing 3-1/16" 15M flanged wellhead assemblies with standard 3-inch 1502 temporary pipework.

Quality Assurance

Each crossover adapter undergoes rigorous quality inspection protocols, including severe hydrostatic shell testing, dimensional checks, precise thread and wing nut gauging, and material traceability verification (MTRs), ensuring reliable and repeatable pressure containment in the most challenging operational field conditions.
