2" Fig 1502 Butt Weld (Sch XH) Hammer Union – Oil & Gas Flowline Fitting

The 2" Figure 1502 Butt Weld Schedule XH Hammer Union is an extreme-duty, ultra-high-pressure flow control component expertly engineered for permanent, highly secure fluid routing in the most demanding upstream oil and gas operations. Rated for a massive 15,000 PSI Cold Working Pressure (15M CWP), this highly resilient hammer union provides a dependable, fast-makeup connection between welded 2-inch piping systems. It is an essential, industry-standard asset for heavy-duty fracturing iron, permanent cementing manifolds, acidizing, high-pressure well testing, and severe choke-and-kill line configurations.

Unlike threaded unions, this Figure 1502 assembly features precision-machined Butt Weld ends matching Schedule XH (Extra Heavy) pipe dimensions. This design allows for a permanent, full-penetration welded integration into high-pressure pipework, effectively eliminating the risk of thread-related leaks or backing-off caused by the severe vibration and pressure pulsations typical of massive pumping operations.

Manufactured from premium high-strength forged alloy steel, the union features a specialized, replaceable lip-type elastomeric seal ring that fits securely into the female sub. This primary seal effectively protects the secondary metal-to-metal seating surface from abrasive frac fluids and corrosive agents, ensuring absolute bubble-tight pressure containment under immense loads. The robust, heavy-duty wing nut design enables fast, tool-free assembly and dismantling of the welded spools in the field, critically reducing rig-up times while maximizing structural safety.

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.

• 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 and cyclic fatigue.

• Replaceable Lip-Type Seal: Features a resilient elastomeric seal ring that provides a dependable primary barrier, minimizing turbulence and protecting metal seating surfaces from abrasion.

• Dual Sealing Mechanism: Combines the primary elastomer seal with a precision-machined secondary metal-to-metal seat for ultimate, leak-free pressure containment.

• 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 hammer union 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 general oilfield fluid routing where welded connections are preferred for maximum safety under 15,000 PSI pressure.

Quality Assurance

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