2" 15,000 PSI Fig 2202 Sour Service Hammer Union Retainer Ring – Oil & Gas Replacement Part

The 2" Figure 2202 Retainer Ring is a critical replacement component engineered to safely and securely lock the wing nut onto the male sub of a high-pressure, sour service hammer union assembly. Specifically designed for Figure 2202 systems—which are built to handle 15,000 PSI Cold Working Pressure (CWP) in hazardous hydrogen sulfide (H2S) environments—this retaining ring ensures the union remains securely assembled during rigorous well-testing, fracturing, and production operations.

Manufactured from specially heat-treated, high-strength alloy steel, this retainer ring is designed to resist sulfide stress cracking (SSC) and hydrogen embrittlement, aligning with the stringent safety requirements of sour gas service. It provides a precise, direct-fit replacement for worn, stretched, or damaged rings, allowing operators to safely refurbish existing H2S-rated flowline iron rather than replacing the entire union assembly.

Designed for absolute safety in toxic environments, the 2" 2202 Retainer Ring is an essential maintenance item for keeping your sour service flowlines and choke manifolds operating safely and efficiently.

Features & Benefits

• Secure Nut Retention: Firmly locks the heavy-duty wing nut onto the sour service male sub, preventing accidental disassembly under extreme pressure.

• Figure 2202 Compatibility: Specifically designed for 15,000 PSI CWP hammer unions rated for sour gas (H2S) service.

• SSC Resistant Material: Manufactured from specially heat-treated steel to prevent hydrogen embrittlement and sulfide stress cracking.

• Direct Replacement: Precision-engineered to perfectly fit standard 2" Figure 2202 male subs and wing nuts.

• Cost-Effective Maintenance: Allows for the safe repair and refurbishment of specialized sour service flowline iron.

• Field Essential: A crucial spare part for rapid on-site repairs during critical sour well rig-ups and flowline maintenance.

Specifications & Technical Details

Applications

This 2" Figure 2202 retainer ring is essential for the maintenance and repair of high-pressure, sour gas flowline equipment. Typical applications include refurbishing H2S-rated frac iron, repairing sour service well-testing manifolds, and replacing worn or damaged rings on choke and kill lines exposed to lethal sour gases.

Quality Assurance

Each retainer ring is manufactured under strict quality control standards, undergoing rigorous dimensional inspection and hardness testing to ensure perfect fitment, NACE compliance compatibility, and reliable performance within highly volatile sour service assemblies.
