Weld Neck Flanges

Weld Neck Flanges (WN Flanges) are pipe flanges featuring a long, tapered hub that transitions the thickness of the flange to match the thickness of the pipe wall. Zeron Fastners manufactures these critical components primarily through the forging process. [Image of Weld Neck Flange diagram] The design allows the flange to be joined to the pipe with a butt-weld, providing the highest integrity, strongest, and most stress-distributing joint possible. This makes WN Flanges the preferred choice for severe service, high-pressure, and high-temperature applications where leak integrity is paramount. We supply WN Flanges in grades ranging from high-creep-resistant alloy steels (B16) to specialized nickel superalloys (Inconel 718, Hastelloy) for corrosive environments.
