What is a Weld Neck Flange?
A Weld Neck Flange (WN Flange) features a long tapered hub that distributes stress evenly between the pipe and flange connection. This design ensures leak-proof performance, high strength, and durability—making it the preferred choice for pipelines and critical industrial systems.
Why Choose Our Weld Neck Flanges?
♦ Superior Engineering: Precision-designed with tapered hubs that minimize stress at the weld joint.
♦ Pressure Range: Available from Class 150 to Class 2500, covering all major pressure ratings.
♦ Material Options: Manufactured in Carbon Steel, Stainless Steel, Duplex, Super Duplex, Alloy Steel, and Nickel Alloys.
♦ Face & Connection Types: Raised Face (RF), Ring Type Joint (RTJ), Flat Face (FF), and Tongue & Groove.
♦ Certifications & Testing: Each flange undergoes 100% radiography testing, mechanical tests, NDT, and ISO-certified quality checks.
