3" Figure 1502 Hammer Union Retainer Segments (Set of 3) – Oil & Gas Flowline Part

The 3" Figure 1502 Retainer Segment Set is a critical structural component of the high-pressure hammer union assembly. Consisting of three precision-machined curved pieces, these segments fit into the external groove of a 3" Fig 1502 male sub. Their primary function is to act as a heavy-duty load-bearing shoulder that the wing nut pulls against, allowing the union to be tightened to a blowout-proof, 15,000 PSI seal.

Manufactured from high-strength forged alloy steel and heat-treated for maximum toughness, these segments are designed to withstand the massive axial loads and extreme mechanical shocks encountered during hydraulic fracturing, cementing, and high-pressure well testing. Because the wing nut depends entirely on these segments for its "grip" on the male sub, their structural integrity is paramount for operator safety and pressure containment.

Sold as a complete set of three, these segments are essential for the maintenance and recertification of flowline iron, allowing field mechanics to rebuild male subs and replace worn wing nuts without the need to replace the entire pipe or swivel joint.

Features & Benefits

• 15,000 PSI CWP Compatibility: Engineered to support the full mechanical load of 3" Figure 1502 connections under extreme field pressures.

• Forged Alloy Steel: Premium material construction ensures resistance to deformation, cracking, and fatigue during heavy hammering.

• Precision Fit: Machined to exact tolerances to ensure 100% contact within the male sub groove and perfect alignment with the wing nut.

• Complete Set of 3: Provided as a full set to ensure uniform wear and consistent load distribution across the union assembly.

• Heat Treated for Durability: Enhanced hardness allows the segments to endure thousands of high-torque make-and-break cycles.

• Cost-Effective Repair: Enables the field-level restoration of male hammer union ends, extending the life of expensive pup joints and swivels.

Specifications & Technical Details

Applications

This 3" Figure 1502 segment set is strictly used for the assembly and repair of high-pressure hammer union connections. Typical applications include rebuilding the male ends of frac iron pup joints, securing wing nuts onto style 10 and style 50 swivel joints, maintaining cement manifolds, and repairing the terminal connections on high-pressure pump trucks.

Quality Assurance

Each segment set is manufactured under rigorous quality control standards. Forgings undergo non-destructive examination (NDE) and strict dimensional checks to ensure they provide a secure, blowout-proof fit. The metallurgical properties are verified to ensure maximum load-bearing capacity under 15,000 PSI operational conditions.
