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

The Crossover Adapter, 3" FIG 1502 Male (Wing) x 3" FIG 1502 Female (Thread) for Sour Service, is a highly specialized, heavy-duty flowline component engineered to safely extend connections, protect permanent manifold equipment, or provide essential spacing within a large-bore 15,000 PSI high-pressure piping system exposed to toxic H2S environments.

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 large-bore 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.

Because both ends feature the standard 3-inch FIG 1502 profile, this component seamlessly integrates into existing large-capacity flowlines without restricting the internal flow path. Frequently utilized as a large-bore "saver sub," it provides field operators with crucial rig-up flexibility. When installed onto expensive, permanent sour service manifold equipment (such as a high-yield choke manifold), it takes the brunt of the daily hammer make-up and break-out wear, protecting the critical, high-value master threads from mechanical damage.

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.

• Male x Female Configuration: Acts as a direct extension or "saver sub" to protect the threads and sealing surfaces of permanent, high-value flowline equipment in corrosive environments.

• 15K High-Volume Capacity: Maintains an uninterrupted 3-inch flow path rated for a full 15,000 PSI cold working pressure under severe chemical and mechanical stress.

• Reduced Equipment Wear: By absorbing the repeated shock and mechanical stress of rig hammer blows during routine rig-ups, it dramatically extends the lifespan of primary manifold connections.

• Reliable Sealing: Precision-machined seating surfaces ensure compatible sour service elastomeric seals seat perfectly for a bubble-tight, leak-free connection.

Specifications & Technical Details

Applications

This sour service 3-inch Male x Female adapter is a mandatory safety asset for high-pressure surface operations involving corrosive gases where standard large-bore 15K lines require a slight extension, or where primary equipment threads need protection from continuous rig-ups. Typical applications include toxic well testing packages, large-volume 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 hardness 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.
