Welded Flowline Elbow – 4" FIG 206 Male (Wing) x 4" FIG 206 Female (Thread) | Butt Welded, SCH XH

The Welded Flowline Elbow, 4" FIG 206 Male (Wing) x 4" FIG 206 Female (Thread), is a massive, heavy-duty fabricated directional component designed to change flow geometry by 90 degrees within large-volume, low-pressure fluid transfer networks. Utilizing a robust Butt Welded Schedule XH (Extra Heavy) pipe construction, this 4-inch large-bore elbow provides a reliable, high-integrity bend for massive utility lines, preventing pipeline strain while maintaining a continuous 2,000 PSI cold working pressure.

In large-scale low-pressure surface setups, standard threaded elbows can suffer from thread engagement failures or leaks under continuous operational vibration and weight. By utilizing an integral butt-welded assembly fabricated with premium 4-inch Schedule XH pipe, this component offers exceptional resistance to structural fatigue and wall-thinning caused by low-pressure abrasive slurries, mud, and continuous water transfer. It creates a seamless change in direction, eliminating the hazardous requirement to stack multiple threaded fittings.

The 4" FIG 206 male end is equipped with a standard low-pressure, large-bore wingnut configuration and incorporates the signature FIG 206 primary O-ring seal, ensuring reliable, bubble-tight fluid containment even in extreme-volume vacuum or suction applications. The opposing 4" FIG 206 female end provides a precision-machined thread (sub) connection designed to seat a standard 4-inch FIG 206 male wing profile, allowing for fast, adapter-free inline installation.

Features & Benefits

• Streamlined 90-Degree Redirection: Provides a clean, permanent 90-degree turn in massive 4-inch line piping, optimizing fluid transfer paths without sacrificing massive bore volume.

• Butt Welded SCH XH Construction: Fabricated using premium 4-inch Schedule XH (Extra Heavy) pipe to provide superior structural rigidity, vibration resistance, and durability in high-volume utility transfer lines.

• O-Ring Sealed Profile: The FIG 206 male end features a primary O-ring seal, guaranteeing leak-free performance in both pressurized fluid transfer and heavy suction applications.

• 2,000 PSI Working Capacity: Safely maintains a continuous pressure rating of 2,000 PSI (2K CWP), perfectly suited for standard oil, water, mud, or utility services.

• Male x Female Configuration: Features a standard 4-inch 206 wingnut on one end and a precision 206 threaded sub on the other, allowing direct inline integration into massive hammer union runs.

Specifications & Technical Details

Applications

This butt-welded 4-inch FIG 206 hammer union elbow is commonly used in heavy-duty surface applications requiring robust, low-pressure fluid routing at extreme volumes. Typical applications include massive mud tank mixing and suction lines, high-capacity water transfer manifolds, large-bore pipeline manifold corners, and general oilfield fluid handling infrastructure where a reliable 4" FIG 206 Male-to-Female turn is required.

Quality Assurance

All our welded flowline elbows are fabricated by certified welders using premium steel and subjected to strict quality control processes. Each fabricated fitting undergoes rigorous weld inspection and hydrostatic pressure testing prior to shipment to ensure absolute safety, shell integrity, and seal performance under working loads. Full material traceability is available to guarantee compliance with industry guidelines.
