Crossover Adapter – 3" FIG 1502 Female (Thread) x 2" FIG 1502 Male (Wing) | Sour Service (H2S)

The Crossover Adapter, 3" FIG 1502 Female (Thread) x 2" FIG 1502 Male (Wing) for Sour Service, is a highly specialized, heavy-duty flowline component engineered to safely step down pipe diameter while maintaining a consistent 15,000 PSI high-pressure rating in hazardous, highly corrosive H2S environments. This crucial adapter allows field operators to seamlessly transition from larger high-volume 3-inch FIG 1502 flowline iron down to standard 2-inch FIG 1502 equipment without compromising structural integrity or personnel safety.

Operating in sour gas (H2S) environments subjects high-pressure flowline iron to extreme risks of hydrogen embrittlement and Sulfide Stress Cracking (SSC). To guarantee maximum safety and absolute compliance, this entire step-down crossover 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 sour service operations.

A defining feature of this crossover is its Female x Male (Thread x Wing) configuration. The 3-inch end features a precision-machined female thread (sub) connection, while the 2-inch end is equipped with a standard heavy-duty male wingnut. This configuration makes it an indispensable solution for directly connecting a 3-inch male manifold component into a 2-inch female distribution line. By bridging these connections directly, this adapter eliminates the need for stacking multiple forged swages, which significantly reduces the overall rig-up footprint, minimizes potential leak paths, and limits hazardous exposure points across the high-pressure system.

Features & Benefits

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

• Female x Male Configuration: Features a 3-inch threaded female end and a 2-inch male winged end, providing a direct, streamlined solution for stepping down line sizes in complex sour rig-ups.

• 15K High-Pressure Rating: Engineered to safely handle a full 15,000 PSI cold working pressure across the transition under severe chemical and mechanical stress.

• Reduced Leak Paths: Single-piece forged construction replaces dangerous "stacked" adapter configurations, drastically lowering operational risks in toxic gas environments.

• Fast Field Installation: The 2-inch FIG 1502 male end includes a heavy-duty wingnut, allowing for rapid, secure makeup and breakout using standard rig hammers.

Specifications & Technical Details

Applications

This Female x Male step-down adapter is a mandatory safety asset for high-pressure surface operations involving corrosive gases where transitioning from 3-inch lines to 2-inch distribution lines is required. Typical applications include toxic well testing packages, H2S choke and kill manifolds, sour frac-flowback iron rig-ups, acidizing systems, and general production manifolds requiring reliable, NACE-compliant 15,000 PSI step-down connections.

Quality Assurance

All our sour service adapters undergo rigorous quality control and non-destructive metallurgical verification. The forged bodies are strictly tested for precise hardness limits to guarantee maximum resilience against Sulfide Stress Cracking. Each unit undergoes precise 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.
