2" Fig 1502 Butt Weld (Sch XH) Male Sub with Wing Nut – Hammer Union Component

The 2" Figure 1502 Butt Weld (Schedule XH) Male Sub with Wing Nut is an extreme-duty, high-pressure flow control component engineered for permanent, highly secure fluid routing in demanding upstream oil and gas operations. Rated for a massive 15,000 PSI Cold Working Pressure (15M CWP), this heavy-duty component combo serves as the dynamic half of a complete Figure 1502 assembly. It provides the essential metal-to-metal seating surface and the heavy-duty wing nut required to rapidly connect welded 2-inch piping systems in fracturing, cementing, and choke-and-kill applications.

Designed with precision-machined Butt Weld ends perfectly matching Schedule XH (Extra Heavy) pipe dimensions, this male sub allows for a permanent, full-penetration welded integration into high-pressure pipework. This welded configuration effectively eliminates the risk of thread-related leaks, galling, or backing-off caused by the severe vibration, heavy mechanical loads, and pressure pulsations typical of massive pumping operations.

Manufactured from premium high-strength forged alloy steel, this male sub and wing nut assembly is built to endure highly abrasive environments and extreme mechanical impacts. The integral spherical seating surface of the male sub is precision-machined to mate perfectly with the elastomeric seal and conical seat of a standard 2-inch 1502 female sub, ensuring absolute bubble-tight pressure containment. The heavy-duty wing nut enables fast, tool-free assembly and dismantling of welded spools in the field, optimizing operational efficiency.

Features & Benefits

• 15,000 PSI Pressure Rating (15M): Engineered to safely manage extreme ultra-high-pressure fluid systems with a 15,000 PSI Cold Working Pressure rating.

• Component Specific Assembly: Includes the rugged male sub and heavy-duty wing nut, serving as an ideal replacement part or fabrication component for custom welded manifolds.

• Butt Weld Connection (Sch XH): Precision-beveled ends designed for Schedule XH pipe allow for permanent, high-integrity welded connections, providing superior resistance to vibration.

• Precision Seating Surface: The precision-machined spherical tip ensures an optimal metal-to-metal seat when paired with a corresponding Figure 1502 female sub.

• Forged Alloy Steel Construction: Built from heavy-duty forged alloy steel to deliver exceptional durability and resistance against severe mechanical impacts and high-velocity frac fluids.

• Rapid Spool Makeup: The heavy-duty wing nut allows for quick, ultra-secure connections and disconnections between welded pipe spools in the field.

Specifications & Technical Details

Applications

This ultra-high-pressure 2" Figure 1502 butt weld male sub with wing nut is essential for upstream operations requiring extremely reliable fluid containment and structural rigidity. Typical applications include the fabrication of heavy-duty permanent frac iron, truck-mounted cementing manifolds, high-pressure acidizing networks, surface well testing flowlines, and replacing damaged male ends on existing welded assemblies to maintain maximum safety under 15,000 PSI pressure.

Quality Assurance

Each component undergoes rigorous quality control protocols, including precision dimensional verification of the weld bevels and seating surfaces, full material traceability (MTRs), and compliance with strict industry manufacturing standards to ensure complete structural integrity and safe pressure containment.
