An 18 Inch Weld Neck Flange is engineered for large-diameter pipelines that require maximum strength and reliability under high-pressure and high-temperature conditions. Designed with a long tapered hub, this flange ensures smooth stress distribution between the pipe and flange, reducing the risk of structural failure and enhancing durability. Manufactured as per ASME B16.5, it guarantees dimensional precision, strong butt-weld connections, and leak-proof performance in demanding industrial systems.

The weld neck design minimizes turbulence and erosion within the pipeline, making it suitable for critical applications in oil & gas, petrochemical, refinery, offshore, marine, and power generation industries. Available in a wide range of materials and pressure classes, the 18 Inch Weld Neck Flange provides excellent corrosion resistance and mechanical strength for long-term service in aggressive environments.
