Dhodi Metal Industries is one of the leading manufacturers, suppliers, and exporters of Copper Nickel Alloy Flanges. We offer these pipe flanges in a variety of shapes, sizes, diameters, material grades, and other criteria. We manufacture Copper Nickel Alloy Flanges using high-quality materials and modern manufacturing procedures and offer them to both domestic and worldwide markets.

Copper Nickel 90/10 and 70/30 alloy flanges are indeed well-regarded for their unique properties, making them highly suitable for demanding environments like seawater systems, desalination plants, and marine engineering. Copper Nickel 90/10 Alloy Flanges are very resistant to seawater corrosion because to the high manganese and iron content. Similarly, Copper Nickel 70/30 Alloy Flanges are highly durable and resistant to heat and corrosion. We make a wide range of flanges, including Copper Nickel Slip On Flanges, Copper Nickel Orifice Flanges, Copper Nickel Threaded Flanges, Copper Nickel Spacer Flanges, Copper Nickel Lap Joint Flanges, and more.

Copper nickel flanges are integral parts of piping systems, often used to connect pipes, valves, pumps, and other equipment. Known for their high resistance to corrosion, especially in seawater and marine environments, copper nickel flanges are favored in industries like marine, desalination, oil and gas, and power generation.

Copper nickel flanges are typically made from two main grades of copper-nickel alloys: Cu-Ni 90/10: Composed of 90% copper and 10% nickel, suitable for seawater applications and less demanding environments. Cu-Ni 70/30: Composed of 70% copper and 30% nickel, offering superior strength and corrosion resistance, particularly in harsh marine environments.

Common Types of Copper Nickel Flanges:

1. Copper Nickel Weld Neck Flanges: These flanges have a long tapered hub and are welded to the pipe. They are ideal for high-pressure applications.

2. Copper Nickel Slip-On Flanges: Slip over the pipe and are welded both inside and outside for a secure fit. Commonly used in low-pressure applications.

3. Copper Nickel Socket Weld Flanges: Have a recessed area where the pipe fits into, and a single fillet weld is used to connect the flange and pipe.

4. Copper Nickel Blind Flanges: Used to close off piping systems or vessels and can be removed when needed for maintenance.

5. Copper Nickel Lap Joint Flanges: Work with stub end fittings and are used in systems where frequent dismantling is needed.

6. Copper Nickel Threaded Flanges: Threaded to attach to pipes without welding, commonly used in lower pressure applications.
