Niobium flanges are pipe fittings composed of the metal niobium, which is extremely resistant to heat and corrosion. These flanges are utilized in high-performance sectors including nuclear, chemical processing, aerospace, and marine applications because of their resilience to harsh chemicals, high pressure, and extremely high temperatures. For certain applications where traditional materials fall short, their exceptional oxidation resistance and strength at elevated temperatures make them perfect.

Niobium flanges come in various types, including weld neck, slip-on, blind, socket weld, threaded, and lap joint flanges. Weld neck flanges are ideal for high-pressure applications, slip-on flanges provide easy installation, blind flanges are used to close pipelines, socket weld flanges offer strong connections for small pipe diameters, and threaded flanges allow for easy assembly without welding.
