Seawater corrosion of cupro nickel flanges
The Cupro nickel flanges are marine quality grade designed to work in harsh seawater applications. The copper and nickel content in the copper nickel slip on flange makes it highly tolerant to corrosive affluents. Furthermore, it is ductile and can be easily welded and work in marine systems. The copper nickel backing rings are tolerant to crevice corrosion and pitting by acids. This makes them a viable choice in the harsh seawater system.
