Incoloy 825 Weld Neck Flanges
Incoloy 825 Weld Neck Flanges are specialized pipe fittings, manufactured by Zeron Fastners,
designed for high-integrity, demanding piping systems. The unique design features a long tapered hub
that is butt-welded to the pipe, providing mechanical reinforcement and minimizing turbulence at the
joint. These flanges are forged from the high-performance alloy Incoloy 825 (UNS N08825), a complex
alloy rich in nickel, chromium, molybdenum, and copper. This composition ensures outstanding
resistance to a wide range of corrosive attacks, including exceptional immunity to stress-corrosion
cracking in chloride-bearing environments and superior defense against reducing acids like sulfuric
and phosphoric acid. Due to the high strength and critical nature of their connection, Weld Neck
Flanges are preferred for high-pressure, high-temperature, and fluctuating temperature applications
in the chemical, oil and gas, and nuclear industries.
