Flowline Cross – 3" FIG 1502 3-Way Female (Thread) x 1-Way Male (Wing) | Sour Service (H2S)

The Flowline Cross, 3" FIG 1502 featuring three Female (Thread) ends and one Male (Wing) end for Sour Service, is a massive, highly specialized forged steel four-way manifold component engineered for extreme-volume, high-pressure operations in toxic H2S environments. Designed to safely distribute, combine, or divert corrosive fluid streams up to 15,000 PSI, this critical large-bore fitting allows field operators to efficiently branch a single 3-inch flowline into three distinct directions, or converge three massive lines into one, without sacrificing structural integrity or operator 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 cross 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.

This specific cross features a specialized FxFxFxM (3 Female x 1 Male) configuration. Three ports are equipped with precision-machined female thread (sub) connections designed to safely seat standard 3-inch 1502 male wing profiles. The fourth port features a heavy-duty large-bore male wing configuration complete with a wingnut for fast, secure hammer-up installation into existing female equipment.

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.

• Four-Way Flow Distribution: Efficiently splits or combines extreme-volume, high-pressure toxic fluid streams across four intersecting large-bore ports.

• FxFxFxM Configuration: Features three female (thread/sub) ports and one male (wing) port, allowing for seamless, direct integration into specifically engineered piping layouts.

• Full 15K CWP Capacity: Maintains an uninterrupted high-pressure rating of 15,000 PSI (15K CWP) across all four intersecting branches, built for extreme and toxic oilfield environments.

• Reduced Leak Paths: Single-piece integral forged construction eliminates the hazardous need for building multi-piece "stacked tee" workarounds, drastically lowering operational risk in lethal gas zones.

Specifications & Technical Details

Applications

This sour service 3-inch FxFxFxM Flowline Cross is a mandatory safety asset for high-pressure, high-volume surface operations involving corrosive gases. Typical applications include building massive sour frac manifolds, toxic high-rate well testing packages, H2S choke and kill manifolds, acidizing lines, and large-bore pump discharge headers requiring reliable, NACE-compliant 15,000 PSI 4-way connections.

Quality Assurance

All our sour service integral fittings 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 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.
