Copper Nickel Slip On Flange and Cuni Flange suppliers in UAE
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.
