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

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

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 and absolute field 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 hazardous sour service applications.

A defining feature of this adapter is its Male x Male (Wing x Wing) configuration. Equipped with heavy-duty wingnuts on both ends (one 3-inch and one 2-inch), it provides an indispensable, direct solution for joining a 3-inch female (thread/sub) manifold connection to a 2-inch female (thread/sub) distribution line. By bridging these two differently sized female connections with a single, integral component, it eliminates the need for stacking hazardous combinations of multiple swages or temporary lines. This drastically lowers the overall rig-up footprint, minimizes potential leak paths, and reduces hazardous exposure points across the high-pressure system.

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 corrosive H2S environments.

• Male x Male Configuration: Dual wingnut configuration provides a direct, streamlined solution for mating two female (thread/sub) union connections of different sizes.

• Seamless Step-Down Transition: Safely handles fluid volume reduction from a 3-inch large-bore manifold line down to a standard 2-inch distribution line.

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

• Reduced System Risk: Single-piece integral forging eliminates dangerous "stacked" adapter configurations, significantly minimizing potential failure points in toxic gas zones.

• Fast Field Installation: Double wingnut design allows for rapid, secure makeup and breakout on both sides using standard rig hammers.

Specifications & Technical Details

Applications

This sour service Male 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, specifically when two female components must be directly joined. 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 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.
