2" FIG 1502 Adjustable Choke Assembly – Sour Service (With Tap, Without Plugs)

The 2" FIG 1502 Adjustable Choke Assembly for Sour Service is a premium, heavy-duty flow control valve engineered specifically to handle the harsh and corrosive conditions of H2S environments. Featuring integral 2-inch FIG 1502 hammer union end connections, this robust assembly safely manages extreme working pressures up to 15,000 PSI (15K CWP). It is specifically manufactured to meet strict NACE MR0175 / ISO 15156 standards, making it an essential, fail-safe component for sour gas well testing, highly corrosive flowback operations, and specialized choke manifold systems.

This adjustable assembly features a highly precise conical stem and seat mechanism, allowing operators to continuously adjust fluid flow and manage pressure drops safely without shutting in the well. The exterior includes a calibrated indicator scale for accurate and repeatable orifice size adjustments.

Furthermore, this specialized choke body includes an integrated tapped port ("With Tap"), which provides a direct and convenient connection point for pressure gauges, sensors, or fluid sampling lines. It is intentionally supplied "Without Plugs," giving field personnel the flexibility to install their specific instrumentation or custom sealing plugs exactly as required by their operational setup.

Features & Benefits

• Sour Service Compliant: Manufactured from highly specialized, corrosion-resistant steel alloys and heat-treated to comply strictly with NACE MR0175 standards for safe H2S operation.

• Extreme Pressure Rating: Built to withstand up to 15,000 PSI cold working pressure in the most demanding drilling and production environments.

• Precise Flow Control: Externally adjustable stem with a calibrated indicator allows operators to safely monitor and manipulate the flow rate in increments of 1/64".

• Integral Tapped Port: The body tap provides quick access for pressure monitoring equipment directly at the choke, enhancing safety and situational awareness.

• FIG 1502 Connections: Integral hammer union ends ensure fast, secure, and leak-free makeup and breakout in the field under extreme pressure.

• Erosion Resistant Trim: Internal wear components are crafted from high-grade tungsten carbide or specialized alloys to resist the highly abrasive and corrosive nature of sour well fluids.

Specifications & Technical Details

Applications

The 2" FIG 1502 Adjustable Choke Assembly for Sour Service is a critical asset for surface pressure control in hazardous environments. Typical applications include choke and kill manifolds, sour well testing packages, H2S flowback iron setups, frac-flowback operations, and production manifolds where dynamic control of highly pressurized, corrosive well fluids and gases is mandatory.

Quality Assurance

All our sour service choke assemblies undergo rigorous metallurgical testing and strict quality control processes. Each unit undergoes strict hydrostatic pressure testing prior to shipment to ensure shell integrity and seal performance under maximum working loads. Full material traceability, NACE certification, and testing documentation are available to guarantee unmatched safety and compliance in the field.
