3" Fig 602 Butt Weld (Sch XXH) Female Sub – Hammer Union Component

The 3" Figure 602 Butt Weld (Schedule XXH) Female Sub is a heavy-duty, high-capacity flow control component engineered for permanent, maximum-security fluid routing in medium-to-high pressure upstream and midstream operations. Rated for a 6,000 PSI Cold Working Pressure (CWP), this robust component serves as the static half of a complete large-bore Figure 602 assembly. It is explicitly designed to house the specialized Figure 602 lip-type elastomeric seal ring, providing the critical foundation for a bubble-tight, leak-free connection in heavy-duty cementing, massive mud lines, and truck-mounted pumping applications.

Designed with precision-machined Butt Weld ends perfectly matching Schedule XXH (Double Extra Heavy) pipe dimensions, this female sub allows for a permanent, full-penetration welded integration into medium-pressure pipework. This exceptionally thick-walled configuration provides superior erosion allowance against highly abrasive fluids and eliminates the risk of thread-related leaks or loosening caused by the severe vibration and mechanical loads typical of massive, high-volume fluid transfers.

Manufactured from premium high-strength forged steel, this female sub is built to endure extreme mechanical impacts and continuous, high-velocity flow. The precision-machined internal recess is manufactured to exact tolerances to perfectly seat the resilient lip-type seal, effectively protecting the secondary metal-to-metal seating surfaces from abrasive damage when paired with a matching male sub.

Features & Benefits

• 6,000 PSI Pressure Rating: Engineered to safely manage continuous fluid transfer in medium-to-high pressure systems with a reliable 6,000 PSI Cold Working Pressure rating.

• Component Specific Application: Includes the rugged female sub only, serving as an ideal replacement part or foundational fabrication component for custom large-bore welded manifolds.

• Butt Weld Connection (Sch XXH): Precision-beveled ends designed for Schedule XXH pipe provide maximum wall thickness, offering unmatched resistance to abrasive erosion and continuous vibration.

• High Flow Capacity: The massive 3-inch bore safely accommodates the high-volume fluid transfers required for modern severe-service pumping and cementing applications.

• Precision Seal Housing: Features an exactingly machined internal groove designed to securely house the standard Figure 602 replaceable lip-type elastomeric seal.

• Forged Steel Construction: Built from heavy-duty forged steel to deliver exceptional durability and resistance against mechanical impacts and rough field handling.

Specifications & Technical Details

Applications

This heavy-duty 3" Figure 602 Schedule XXH butt weld female sub is strictly essential for flowline networks requiring extreme structural rigidity, superior erosion resistance, and massive flow capabilities. Typical applications include the fabrication of permanent high-capacity truck-mounted pumping manifolds, massive cementing lines, severe-service mud and slurry transfer networks, and replacing damaged female ends on existing welded assemblies to maintain maximum safety under 6,000 PSI pressure.

Quality Assurance

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