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

The 3" Figure 1502 Positive Choke Blind is a heavy-duty, high-pressure sealing component designed to securely cap or isolate the flow path in positive choke valve bodies. Engineered for the extreme conditions of the oilfield, this blind plug is rated for a Cold Working Pressure (CWP) of 15,000 PSI, making it an essential tool for well testing, flowback, and stimulation operations where absolute pressure containment is required.

Manufactured from high-strength forged alloy steel, the 3" 1502 choke blind is built to withstand mechanical shock, vibration, and the erosive effects of high-velocity abrasive fluids. The precision-machined hammer union connection ensures full interchangeability with standard 3" Figure 1502 female subs or choke bodies. It utilizes a high-pressure elastomeric seal to achieve a bubble-tight, blowout-proof closure, allowing operators to safely isolate manifolds or perform maintenance on downstream equipment without depressurizing the entire system.

Designed for rapid deployment and maximum field reliability, this positive choke blind ensures a robust and safe termination point for high-pressure flowline iron.

Features & Benefits

• 15,000 PSI CWP Rating: Specifically designed for extreme-pressure service in critical upstream environments.

• Forged Alloy Steel Construction: Delivers superior structural integrity and resistance to fatigue and impact.

• Positive Sealing: Incorporates a high-pressure lip seal or O-ring for a dependable, leak-free isolation.

• Figure 1502 Interchangeability: Standardized hammer union design ensures compatibility with all industry-standard 3" 1502 connections.

• Erosion Resistant: Built to handle abrasive fracturing fluids, sand, and high-velocity hydrocarbons.

• Rapid Installation: Allows for fast make-up and break-out using standard hammer union wing nuts.

Specifications & Technical Details

Applications

This 3" Figure 1502 positive choke blind is ideal for applications requiring high-pressure isolation or flowline termination. Typical uses include capping off unused ports in positive choke manifolds, isolating well-testing lines during equipment changes, and securing high-pressure pump discharge lines in fracturing and cementing operations.

Quality Assurance

Each blind is manufactured under rigorous quality control protocols, undergoing precise dimensional inspection and non-destructive examination (NDE) to guarantee structural integrity and safe performance under 15,000 PSI operational loads.
