3" Fig 1502 Integral Pup Joint (M x F) – 10 FT | High-Pressure Flowline Pipe

The 3" Figure 1502 Integral Pup Joint (10 FT) is a heavy-duty, extreme-pressure flowline component engineered for safely transporting high-volume, high-velocity, abrasive fluids in the most demanding upstream operations. Measuring a substantial 10 feet in length, this extended-reach straight pipe segment is essential for safely bridging massive gaps between pumping equipment, spanning long distances across the well pad, and seamlessly connecting distant components within large-scale frac iron spreads. Rated for a massive 15,000 PSI Cold Working Pressure (15M CWP), it provides an ultra-secure, leak-free conduit for critical, large-volume fluid routing while significantly reducing the number of connections required in long pipe runs.

What sets this pup joint apart is its strictly Integral construction. Instead of welding union ends onto a section of pipe or utilizing mechanical threads, this entire 10-foot joint is precision-machined from a single, solid billet of premium high-strength forged alloy steel. This seamless, weld-free design completely eliminates the risk of weld fatigue, heat-affected zone failures, and catastrophic stress cracking under extreme vibration and pressure pulsations, delivering ultimate reliability for severe-service, high-rate stimulation environments.

Configured with industry-standard Figure 1502 Male x Female (M x F) hammer union ends, this pup joint ensures rapid, tool-free rig-up using a standard lead hammer. The Female end houses the hallmark Fig 1502 replaceable lip-type elastomeric seal, which acts as a primary barrier to protect the secondary metal-to-metal seating surfaces from severe abrasive wash-out. Designed for maximum longevity, this massive 10-foot integral pup joint delivers unparalleled structural integrity and pressure containment for heavy-duty well servicing operations.

Features & Benefits

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

• 100% Integral Construction: Machined from a single solid piece of forged alloy steel, completely eliminating weld joints for maximum structural rigidity and fatigue resistance over a 10-foot span.

• Extended 10-Foot Length: Provides long-reach capabilities for safely spanning major distances between pumping equipment, manifolds, and wellheads, minimizing the number of union connections in the line.

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

• Erosion Resistant Bore: The smooth, uninterrupted internal bore minimizes flow turbulence and pressure drops, significantly reducing abrasive internal wear during high-rate frac jobs.

• 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 3" Figure 1502 Integral Pup Joint (10 FT) is an absolutely critical asset for upstream operations requiring maximum flowline strength and high fluid volume over long spans. Typical applications include the construction of extensive severe-service frac iron spreads, reaching across large spacing gaps on well pads, heavy-duty cementing networks, high-pressure flowback operations, and any critical fluid routing where a highly secure, 10-foot 15,000 PSI connection is required.

Quality Assurance

Each integral pup joint undergoes rigorous quality control protocols, including severe hydrostatic pressure testing, complete dimensional verification, ultrasonic thickness (UT) testing to ensure bore concentricity, magnetic particle inspection (MPI) on the union ends, and full material traceability (MTRs) to guarantee fail-safe structural integrity and compliance with strict API standards.
