3-1/8" 3M x 2" Fig 1502 Male Wing Flange Adapter – Oil & Gas Flowline Fitting

The High-Pressure Flange Adapter, 3-1/8" 3M x 2" Fig 1502 Male Wing, is engineered to provide a rapid, ultra-secure crossover connection between standard API 6A flanged wellhead equipment and 2-inch hammer union flowlines. Designed for demanding upstream oilfield operations, this size-adapting crossover allows operators to safely transition from a 3-1/8" 3,000 PSI (3M) flanged connection down to a standard 2" Figure 1502 hammer union interface. The integrated 2-inch male wing nut ensures fast, secure makeup in the field without the need for specialized tooling, critically reducing rig-up times for fluid transfer operations.

Manufactured from high-strength forged alloy steel, this adapter is built to endure the abrasive environments and heavy handling typical of well testing, flow-back, and general fluid transfer. The flanged end conforms strictly to industry dimensional standards for a 3-1/8" bore, while the precision-machined 2-inch 1502 male end with its robust wing nut guarantees a highly vibration-resistant, leak-free seal.

Serving as a critical interface link, this male wing flange adapter optimizes layout flexibility, enabling seamless integration and pipe size reduction between wellhead valving and temporary flowlines. (Note: The maximum working pressure of the complete assembly is governed by the 3,000 PSI rating of the flanged end).

Features & Benefits

• Rapid Makeup Design: Features an integrated 2" Figure 1502 Male Wing Nut for quick, ultra-secure hammer union connections in the field.

• Seamless Size Transition: Safely steps down fluid flow from a larger 3-1/8" 3,000 PSI flanged asset to a standard 2" 1502 temporary iron configuration.

• 3,000 PSI Rating (3M): Engineered to safely contain high-pressure upstream environments, matching the 3,000 PSI maximum rating of the flanged end.

• Forged Alloy Steel Construction: Delivers exceptional durability against abrasive fluids, operational wear, and severe field handling.

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

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

Specifications & Technical Details

Applications

This 3M flange to 2-inch 1502 male wing hammer union adapter is essential for upstream operations requiring flexible structural crossovers, fast rig-up times, and secure pipe size reductions. Typical applications include stepping down flow from wellhead tree components, integrating surface well testing flowlines, temporary flow-back piping, and efficiently interfacing 3-1/8" 3M flanged wellhead assemblies with standard 2-inch 1502 temporary pipework.

Quality Assurance

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