3" Fig 206 Butt Welded Pup Joint (M x F) – 4 FT | Sch XH Flowline Pipe

The 3" Figure 206 Butt Welded Pup Joint (4 FT) is a highly versatile, heavy-duty medium-pressure flowline component engineered for the efficient transport of utility fluids, abrasive drilling mud, and water in rugged oilfield environments. Measuring exactly 4 feet in length, this straight pipe segment provides an optimal mid-range reach, making it essential for adjusting pipeline distances, bridging moderate gaps between equipment, and seamlessly connecting components within manifold spreads. Upgraded with Schedule XH (Extra Heavy) piping and rated for a reliable 2,000 PSI Cold Working Pressure (2M CWP), this unit offers vastly superior structural integrity and abrasion resistance compared to standard pipes.

What differentiates this pup joint is its robust Butt Welded construction utilizing Schedule XH seamless carbon steel pipe, paired with the enhanced sealing capabilities of the Figure 206 hammer union. It is fabricated by taking thicker-walled Extra Heavy pipe and permanently joining it to forged steel Fig 206 union ends using high-penetration butt welds. The increased wall thickness of the Sch XH pipe significantly extends the service life of this 4-foot joint by resisting internal erosion from abrasive slurries, while also offering enhanced resistance to external physical abuse commonly encountered on busy rig floors.

Configured with industry-standard Figure 206 Male (Wing) x Female (Thread) hammer union ends, this pup joint ensures rapid, tool-free rig-up using a standard lead hammer. Unlike standard metal-to-metal unions, the Figure 206 incorporates an elastomeric O-ring mounted in the male sub. This provides an essential secondary seal that works in conjunction with the primary precision-machined steel surfaces, ensuring bubble-tight containment even when dealing with slightly corrosive fluids or minor seating surface abrasions. Designed for demanding utility use, this heavy-wall 4-foot welded pup joint delivers dependable, long-lasting performance for varied fluid routing operations.

Features & Benefits

• 2,000 PSI Pressure Rating: Engineered for medium-pressure fluid systems with a highly reliable 2,000 PSI Cold Working Pressure (2M) rating.

• Figure 206 O-Ring Seal: Features a supplemental elastomeric O-ring in the male sub for superior, leak-free sealing compared to standard metal-to-metal only unions.

• Schedule XH Pipe (Extra Heavy): Built using thick-walled Sch XH seamless steel pipe, providing enhanced durability, superior abrasion resistance, and a longer operational lifespan than standard Sch 40.

• Versatile 4-Foot Length: Provides an optimal mid-range reach required for spacing adjustments and securely connecting manifold components without an excessive footprint.

• Butt Welded Construction: Features full-penetration butt welds connecting the forged union ends to the thick-wall pipe body, ensuring a strong, permanent, and leak-free bond.

• Male (Wing) x Female (Thread) Connections: Features standard Fig 206 hammer union ends for fast, highly secure integration into existing medium-pressure iron networks.

Specifications & Technical Details

Applications

This upgraded 3" Figure 206 Butt Welded Pup Joint (4 FT) is a versatile, heavy-duty asset for operations requiring dependable medium-pressure fluid routing with added durability and sealing security. Typical applications include precise spacing alignments on temporary water supply lines for well pads, abrasive drilling mud circulation surface systems, heavy-duty mid-range connections on suction lines for transfer pumps, and general utility flowlines where extended component life and a secure 4-foot 2,000 PSI connection are required.

Quality Assurance

Each butt welded pup joint undergoes strict quality control protocols to ensure operational safety. This includes hydrostatic pressure testing to verify the integrity of the pipe and seals, complete dimensional verification, and rigorous non-destructive examination (NDE) such as Magnetic Particle Inspection (MPI) or ultrasonic testing on the structural butt welds.
