Long Sweep Elbow – 2" FIG 1502 Male (Wing) x 2" FIG 1502 Male (Wing) | Sour Service (H2S)

The Long Sweep Elbow, 2" FIG 1502 Male (Wing) x 2" FIG 1502 Male (Wing) for Sour Service, is a premium forged steel directional component engineered to safely alter fluid paths in highly toxic H2S environments. Unlike standard short-radius elbows, this specialized fitting features an extended, gradual 90-degree curvature. This "long sweep" geometry significantly reduces fluid friction and lessens the erosive impact of high-velocity, abrasive slurries, making it highly effective for optimizing flow efficiency while maintaining absolute containment integrity.

Operating in sour gas (H2S) environments subjects high-pressure flowline iron to severe risks of hydrogen embrittlement and Sulfide Stress Cracking (SSC). To guarantee maximum safety, this entire elbow body is forged from premium, corrosion-resistant steel alloys and subjected to strictly controlled heat-treatment processes. This ensures the metallurgical properties comply fully with all NACE MR0175 / ISO 15156 performance standards for hazardous sour service applications, safely maintaining a continuous 10,000 PSI cold working pressure (the standard industry de-rating for 1502 sour service iron).

This specific fitting utilizes an MxM (Male x Male) configuration. Both ends of the elbow are equipped with integral 2-inch FIG 1502 male wing profiles, complete with heavy-duty wingnuts. This specialized setup allows field operators to directly connect and bridge two existing female (threaded sub) connection points, providing critical routing flexibility when designing complex, toxic-gas-rated manifold systems.

Features & Benefits

• Sour Service Compliant: Forged from specialized alloys and strictly heat-treated to comply with NACE MR0175 / ISO 15156 standards for safe operation in hazardous H2S environments.

• Long Sweep Geometry: Provides a smooth, extended-radius 90-degree curve that optimizes fluid dynamics, reduces pressure drops, and minimizes velocity-induced erosion.

• Dual Male Configuration (MxM): Equipped with heavy-duty 1502 wingnuts on both ends, allowing for rapid, adapter-free connection between two female ports.

• 10,000 PSI Sour Service Rating: Safely and continuously handles working pressures up to 10,000 PSI (10K CWP), the established safety rating for FIG 1502 sour gas iron.

• Reduced Flow Turbulence: The gradual sweep prevents the sudden fluid impacts associated with sharp turns, protecting both the elbow wall and downstream equipment from premature fatigue.

Specifications & Technical Details

Applications

This sour service 2-inch MxM long sweep elbow is a mandatory safety asset for high-pressure surface routing where low-turbulence fluid transfer is required within toxic gas zones. Typical applications include building massive sour frac manifolds, toxic high-rate well testing packages, H2S flowback lines, choke and kill manifold layouts, and pump discharge headers exposed to corrosive media.

Quality Assurance

All our sour service integral fittings undergo rigorous quality control and non-destructive metallurgical verification. The forged bodies are strictly tested for hardness to guarantee maximum resilience against Sulfide Stress Cracking. Each elbow undergoes rigorous dimensional inspection and hydrostatic pressure testing prior to shipment to ensure absolute shell integrity and leak-free seal seating under maximum working loads. Full material traceability (MTRs) and NACE certificates are available upon request.
