3" 15,000 PSI Fig 1502 Positive Choke Blind Assembly – Oil & Gas Flowline Fitting

The 3" Figure 1502 Positive Choke Blind Assembly is a complete, heavy-duty closure unit engineered to securely isolate or terminate the flow path within high-pressure positive choke manifolds. Rated for a critical Cold Working Pressure (CWP) of 15,000 PSI, this fully integrated assembly provides an immediate, blowout-proof solution for capping unused ports or securing fluid lines during well testing, stimulation, and frac flowback operations.

Unlike a standalone blind plug, this comprehensive assembly typically includes the high-strength blind cap (blanking plug), a rugged Figure 1502 wing nut, retainer ring, and segments, along with the high-pressure elastomeric seal. Manufactured from premium forged alloy steel, the entire unit is built to endure severe mechanical shock, pulsation, and the erosive forces of high-velocity abrasive fluids.

Supplied as a complete, ready-to-install unit, the 3" 1502 Choke Blind Assembly allows rig crews to quickly and safely blank off manifold ports in the field, minimizing equipment downtime and ensuring absolute pressure containment.

Features & Benefits

• Complete Pre-Assembled Unit: Includes the blind plug, heavy-duty wing nut, segments, and seals for rapid, drop-in field installation.

• 15,000 PSI CWP Rating: Specifically designed to safely contain extreme pressures in critical upstream choke and kill applications.

• Forged Alloy Steel Construction: Delivers superior structural integrity, resisting fatigue, impact, and internal erosion.

• Positive Sealing System: Incorporates a high-performance elastomeric seal to achieve a bubble-tight closure.

• Rapid Rig-Up: Eliminates the need to piece together individual hammer union components, speeding up manifold reconfigurations.

• Figure 1502 Interchangeability: Fully compatible with all industry-standard 3" Figure 1502 choke bodies and female subs.

Specifications & Technical Details

Applications

This 3" Figure 1502 positive choke blind assembly is ideal for operations requiring rapid and secure high-pressure flowline termination. Typical uses include capping off unused flow paths in positive choke manifolds, temporarily isolating well-testing lines during equipment change-outs, and securing high-pressure pump discharge headers during fracturing operations.

Quality Assurance

Each blind assembly is manufactured and assembled under rigorous quality control protocols. Components undergo precise dimensional inspection and non-destructive examination (NDE) to guarantee perfect fitment, thread engagement, and reliable blowout-proof performance under maximum 15,000 PSI operational loads.
