Composite Flange Cu-Ni C70600 / Carbon Steel Galvanised – 3″ Class 150#
Designed in Weld Neck (WN) configuration with a Raised Face (RF) sealing surface, it ensures a strong welded joint and reliable gasket sealing. The Cu-Ni stub end comes into direct contact with the process fluid, providing superior resistance to seawater corrosion, while the galvanised carbon steel backing flange handles the bolting load and structural support.
The Composite Flange 3″ Class 150# is engineered to deliver excellent corrosion resistance and mechanical strength in demanding marine and industrial applications. This flange combines a Copper-Nickel C70600 (90/10) stub end with a carbon steel galvanised backing flange, offering the ideal balance between durability, performance, and cost efficiency.
