2" Fig 1502 Integral Pup Joint (M x F) with Filter Sub – 2 FT | High-Pressure Flowline Strainer

The 2" Figure 1502 Integral Pup Joint with integrated Filter Sub (2 FT) is a highly specialized, extreme-pressure flowline component engineered to simultaneously transport fluids and actively protect sensitive downstream equipment. Measuring exactly 2 feet in length, this compact pipe segment features a robust, built-in filtration screen (strainer) designed to catch and trap wellbore debris, milled plug fragments, and large proppant clusters. Rated for a massive 15,000 PSI Cold Working Pressure (15M CWP), it acts as a critical line of defense to prevent catastrophic damage to expensive choke manifold trims, plug valves, and flow meters during severe-service cleanout operations.

What sets this unit apart is its strictly Integral construction combined with high-capacity filtration. The outer body of the 2-foot joint is precision-machined from a single, solid billet of premium high-strength forged alloy steel, completely eliminating the risk of weld fatigue or heat-affected zone failures. Housed internally is a heavy-duty, precisely slotted or perforated filter element engineered to withstand extreme differential pressures without collapsing. This filter allows high-velocity fluids to pass through while securely capturing destructive oversized solids.

Configured with industry-standard Figure 1502 Male x Female (M x F) hammer union ends, this pup joint ensures rapid, tool-free rig-up directly into the flowline just upstream of vulnerable equipment. The Female end houses the hallmark Fig 1502 replaceable lip-type elastomeric seal, providing a bubble-tight primary barrier. Designed for maximum longevity and operational safety, this integral filter pup joint delivers unparalleled structural integrity, precise spacing, and essential debris filtration in a single 2-foot component.

Features & Benefits

• Integrated Filtration: Features a heavy-duty internal strainer element designed to capture wellbore debris and protect sensitive downstream valves and chokes from severe abrasive wash-out.

• 15,000 PSI Pressure Rating (15M): Engineered to safely manage extreme ultra-high-pressure fluid systems with a highly reliable 15,000 PSI Cold Working Pressure rating.

• 100% Integral Body Construction: Machined from a single solid piece of forged alloy steel, completely eliminating weld joints for maximum structural rigidity and fatigue resistance.

• Compact 2-Foot Length: Provides precise, short-span reach while adding crucial filtration capabilities without requiring massive additional iron footprint.

• Male x Female (M x F) Connections: Features standard Fig 1502 hammer union ends for fast, seamless integration directly into existing 15M flowline networks.

• Leak-Free Sealing: Utilizes precision-machined metal-to-metal seats combined with resilient lip-type elastomeric seals for ultimate, bubble-tight pressure containment.

Specifications & Technical Details

Applications

This extreme-pressure 2" Figure 1502 Integral Pup Joint with Filter Sub is an absolutely critical asset for upstream operations where wellbore debris poses a threat to surface equipment. Typical applications include post-frac drill-out and cleanout operations, high-velocity frac flowback, severe-service well testing, and placement immediately upstream of choke-and-kill manifolds to filter out milled composite plugs, rock fragments, and large proppant slugs before they can destroy precision valve internals.

Quality Assurance

Each integral filter pup joint undergoes rigorous quality control protocols. This includes severe hydrostatic pressure testing, complete dimensional verification, ultrasonic thickness (UT) testing, magnetic particle inspection (MPI) on the union ends, and thorough collapse-resistance inspection of the internal filter screen. Full material traceability (MTRs) guarantees fail-safe structural integrity and compliance with strict API standards.
