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

The Crossover Adapter, 3" FIG 1502 Male (Wing) x 2" FIG 1502 Female (Thread) 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 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 Male x Female (Wing x Thread) configuration. The 3-inch end features a standard male wing configuration complete with a heavy-duty wingnut for fast, hammer-up installation into 3-inch female subs, while the 2-inch end provides a precision-machined female thread (sub) connection designed to safely mate with standard 2-inch male wing unions. By bridging this size transition with a single, integral fitting, this adapter eliminates the need for stacking multiple forged swages. This 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 operation in H2S environments.

• Seamless Step-Down Transition: Safely steps down pipe diameter from a 3-inch large-bore line to a standard 2-inch line, providing critical rig-up flexibility in toxic environments.

• 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 hazardous gas environments.

• Fast Field Installation: The 3-inch male wing end includes a heavy-duty wingnut, allowing for rapid, secure makeup and breakout using standard rig hammers.

Specifications & Technical Details

Applications

This Male x Female 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.
