Double Cushion Elbow – 3" FIG 1502 Male (Wing) x 3" FIG 1502 Female (Thread) | Sour Service (H2S)

The Double Cushion Elbow, 3" FIG 1502 Male (Wing) x 3" FIG 1502 Female (Thread) for Sour Service, is a massive, highly specialized flowline component engineered to combat severe velocity-induced erosion in extreme 15,000 PSI treating lines operating within toxic H2S environments. Also known as a target elbow or cushion block, this component features an advanced internal dual-chamber design that traps a small amount of stagnant sand and fluid. This captured media acts as a natural, sacrificial shock absorber, deflecting the punishing force of incoming abrasive materials and shielding the outer steel wall from severe thinning.

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 block 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.

The 3" FIG 1502 configuration provides a standard high-pressure male wing end complete with a heavy-duty wingnut, paired with a precision-machined female thread (sub) connection. This delivers a direct, secure, and leak-free hammer-up connection for high-volume mainlines while ensuring critical operator safety in lethal gas zones.

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.

• Dual-Cushion Erosion Barrier: Built-in stagnation pockets capture abrasive sand and fluid to form a shield, eliminating direct particle impingement against the elbow shell.

• Large-Bore Efficiency: The full 3-inch bore size accommodates massive volumetric flow rates without causing excessive pressure drop or fluid turbulence.

• Full 15K CWP Capacity: Engineered to operate continuously at extreme working pressures up to 15,000 PSI, built for demanding and toxic oilfield environments.

• Direct MxF Connection: Features a standard 3" 1502 wingnut on one side and a threaded sub on the other, allowing fast installation without extra adapter fittings.

Specifications & Technical Details

Applications

This sour service 3-inch double cushion elbow is a mandatory safety asset for high-pressure, high-volume surface operations involving corrosive and abrasive media. Typical applications include building massive sour frac manifolds, toxic high-rate well testing packages, H2S flowback iron corners, sand separator outlet configurations, and any flowline geometry change where high-velocity slurries and sour gas are present.

Quality Assurance

All our sour service integral fittings undergo rigorous quality control and non-destructive metallurgical verification. The forged blocks are strictly tested for hardness to guarantee maximum resilience against Sulfide Stress Cracking. Each fitting 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.
