Welding Neck Flange FF Class 150 – Cu-Ni 90/10 (UNS C70600)
Manufactured in accordance with ASME B16.5 dimensional standards and ASTM B466 / ASTM B151 material specifications, this Cu-Ni 90/10 flange is widely used in seawater cooling systems, shipbuilding, offshore platforms, heat exchangers, desalination plants, and power generation facilities.
The Welding Neck Flange FF Class 150 manufactured from Copper-Nickel 90/10 alloy (UNS C70600) is designed for high reliability in marine, offshore, and corrosive service applications. Known for its excellent resistance to seawater corrosion, erosion, and biofouling, this flange ensures long-term performance in demanding environments.
With a 2″ nominal size, compatible with pipe OD 60.33 mm and 2.5 mm wall thickness, the welding neck design provides superior stress distribution and strong welded joints, making it ideal for high-pressure and high-temperature piping systems. The flat face (FF) configuration ensures secure sealing and easy alignment with gaskets and mating flanges.
