4-1/16" 10M x 3" Fig 1502 Male Wing Flange Adapter – Oil & Gas Flowline Fitting

The Extreme-Pressure Flange Adapter, 4-1/16" 10M x 3" Fig 1502 Male Wing, is a specialized, high-capacity crossover component engineered to provide a rapid, ultra-secure connection between large-bore API 6A flanged equipment and high-volume 3-inch hammer union flowlines. Designed for the most demanding upstream oilfield operations, this size-adapting crossover allows operators to safely and seamlessly transition from a massive 4-1/16" 10,000 PSI (10M) flanged connection to a standard 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 high-volume fluid transfer, severe well testing, and 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 service flow-back, high-rate frac support, and heavy mud systems. The flanged end conforms strictly to industry dimensional and material standards for a 4-1/16" 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 10,000 PSI pressure loads and extreme fluid velocities.

Serving as a vital pressure-control link, this male wing flange adapter optimizes layout flexibility, smoothly bridging large-bore wellhead or manifold setups with temporary standard flowline configurations without compromising structural safety or fluid 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, reducing critical rig-up time.

• Seamless Size Transition: Safely steps down fluid flow from a large-bore 4-1/16" 10,000 PSI flanged asset to a standard 3" 1502 temporary iron configuration.

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

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

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

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

Specifications & Technical Details

Applications

This 10M flange to 3-inch 1502 male wing hammer union adapter is essential for extreme high-pressure upstream operations requiring flexible structural crossovers, fast rig-up times, and high-capacity pipe size reductions. Typical applications include stepping down flow from large 4-1/16" wellhead tree components, integrating high-rate surface well testing flowlines, severe service flow-back piping, heavy-duty frac manifolds, and efficiently interfacing large-bore 10M flanged valve assemblies with standard 3-inch 1502 temporary pipework.

Quality Assurance

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