3" FIG 1502 Choke Tee – Female (Thread) x Female (Thread) x Male (Wing) | Sour Service (H2S)

The 3" FIG 1502 Choke Tee for Sour Service is a highly specialized, high-capacity flowline intersection designed for safely directing, combining, or splitting massive volumes of high-pressure fluid within hazardous H2S environments. Engineered from premium forged alloy steel and rated for 15,000 PSI (15K CWP), this large-bore fitting is a foundational component for constructing reliable choke and kill manifolds, high-rate fracturing setups, and well testing packages in corrosive sour gas operations.

Operating in sour (H2S) environments exposes large-bore flowline iron to the severe risk of Sulfide Stress Cracking (SSC) and rapid material failure. To ensure maximum safety and compliance, this entire tee body is manufactured from highly specialized, corrosion-resistant steel alloys. The metal is strictly heat-treated to controlled maximum hardness levels, meeting or exceeding all NACE MR0175 / ISO 15156 standards for sour service applications.

This specific choke tee features a precision-machined Female (Thread) x Female (Thread) x Male (Wing) hammer union configuration. This asymmetrical setup provides critical flexibility for field personnel when building custom large-bore sour service manifold blocks. It allows operators to connect specific iron orientations seamlessly without the need for unnecessary crossover adapters, thereby reducing the number of potential leak paths and minimizing hazardous exposure points across the system.

Built with extra wall thickness at the intersection point, this 3-inch tee is explicitly designed to withstand the severe internal erosion, extreme fluid velocities, and chaotic turbulence typically encountered when diverting massive volumes of abrasive and corrosive fluids.

Features & Benefits

• Sour Service Compliant: Manufactured from specialized, erosion-resistant alloys and strictly heat-treated to comply with NACE MR0175 / ISO 15156 standards for safe H2S operation.

• Custom Manifold Integration: The specific F(Thread) x F(Thread) x M(Wing) configuration allows for precise, streamlined integration into large-bore sour service choke and kill manifolds and flowback iron rig-ups.

• High-Volume Capacity: The large 3-inch internal bore handles massive fluid volumes safely, making it ideal for high-yield sour wells and heavy frac operations.

• High-Velocity Turbulence Resistance: Engineered with reinforced forged steel walls at the flow intersection to safely absorb shock loads and resist localized erosion from corrosive and abrasive fluids.

• Extreme Pressure Rating: Built to safely withstand 15,000 PSI cold working pressure in the most aggressive and hazardous drilling, testing, and production environments.

• Integral FIG 1502 Connections: Hammer union ends provide fast, secure, and bubble-tight makeup and breakout in the field, essential for limiting H2S exposure.

Specifications & Technical Details

Applications

The 3" FIG 1502 Choke Tee for Sour Service is a mandatory safety asset for high-capacity, high-pressure surface operations involving corrosive gases. Typical applications include the construction of large-bore sour gas choke and kill manifolds, high-rate H2S well testing packages, sour frac-flowback iron rig-ups, and long-term production manifolds requiring reliable, NACE-compliant flow diversion.

Quality Assurance

All our sour service flowline tees are subjected to rigorous metallurgical testing and strict quality control processes. The forged bodies are verified for proper hardness levels to ensure maximum resistance to Sulfide Stress Cracking.
