Copper Nickel Flange

What is copper nickel flange?

Cupronickel flange is an alloy of copper and nickel with strengthening elements like iron and manganese. A  copper nickel flange  is a protruded lip or rim that provides support and stability to different applications. These flanges have good corrosion resistance properties and low macrofouling rates. A  cuni flange  is highly tolerant to seawater corrosion and is commonly available in 90-10 and 70-30 grades.  Copper nickel pipe flanges  are commonly seen in marine equipment, desalination units, seawater piping systems, cooling loops, etc.  Copper nickel flange suppliers  supply flanges in different dimensions to suit different project requirements.

What is the difference between class 150 and 300 cuni flange?

Class 150 and 300 are pressure classes of a  copper nickel composite flange . The   class 300 cuni flange is designed to work in higher pressure and temperature applications. The class 150 flange is designed with less metal and is suited for lower temperature and pressure systems. A class 300  copper nickel threaded flange  is more expensive than the 150 class flange.

What are the uses and application of copper nickel blind flange?

A  copper nickel blind flange  is a device that is used to cut the flow of media in the system. These flanges are blanks that are inserted at the ends of the hydraulic system. A blind  cupro nickel flange  is usually bolted and allows room for cleaning and maintenance of the system. They are commonly used in applications where devices need to be regularly repaired or inspected. The  blind copper nickel pipe flanges   close off various process plants, or when a pipeline is built in stages.

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.
