6" ANSI 300# x 3" Fig 206 Female Thread Flange Adapter – Oil & Gas Flowline Fitting

The 6" ANSI 300# x 3" Fig 206 Female Thread Flange Adapter is a heavy-duty size-reducing crossover component engineered to reliably connect large-diameter permanent facility piping with standard temporary flowlines. Designed for efficient, high-volume fluid transfer in midstream, upstream, and industrial operations, this adapter seamlessly bridges a permanent 6-inch ANSI Class 300 flanged connection down to a versatile 3-inch Figure 206 female hammer union interface.

Manufactured from premium high-strength forged steel, this crossover adapter is built to endure the rigors of heavy field handling, continuous fluid flow, and industrial mechanical impacts. The precision-machined 3-inch female threaded end ensures secure, smooth engagement with standard Figure 206 male hammer union components. The Figure 206 union connection is specifically recognized for its secondary O-ring seal (embedded in the mating male sub), which provides enhanced leak-free performance even in less-than-ideal alignment conditions.

Serving as a durable and critical interface between 6-inch facility infrastructure and 3-inch temporary piping, this flange adapter significantly optimizes layout flexibility while maintaining rigorous structural safety. (Note: The maximum working pressure of the assembly is governed by the ANSI Class 300 flange rating).

Features & Benefits

• Seamless Size Transition: Efficiently steps down massive fluid flow from a larger 6-inch ANSI Class 300 facility pipe directly to a standard 3-inch temporary line.

• Precision-Machined 206 Thread: The 3-inch female union end ensures reliable, smooth engagement with standard Fig 206 male components for rapid rig-up.

• Optimized O-Ring Sealing: Designed to perfectly mate with Fig 206 male subs, utilizing the embedded O-ring for superior, leak-tight sealing in fluid and mud applications.

• Forged Steel Construction: Built to withstand harsh weather, mechanical impacts, and the demanding operational environments of mud and water transfer.

• Versatile Utility: Ideal for high-volume mud systems, massive water transfer networks, chemical injection headers, and general facility tie-ins.

• Optimized Flow Dynamics: Engineered to minimize flow turbulence and pressure drops across the drastic 6-inch to 3-inch size transition.

Specifications & Technical Details

Applications

This ANSI 300# flange to Figure 206 female threaded adapter is essential for operations requiring a secure, durable, and drastic size-reducing transition between permanent facility piping and temporary flowline equipment. Typical applications include midstream facility tie-ins, heavy-duty mud mixing networks, high-volume water transfer stations, suction lines, and standard industrial pump connections where continuous flow is critical.

Quality Assurance

Each crossover adapter undergoes stringent quality control protocols. This includes precise dimensional and thread gauging, flange facing inspection, and material traceability verification, ensuring safe, leak-free, and reliable field performance in everyday transfer applications.
