Copper Nickel Flanges Manufacturer, Supplier & Stockist
Copper Nickel alloys, commonly known as Cupro Nickel, are widely preferred in marine and offshore environments due to their excellent resistance to seawater corrosion, low biofouling tendency, and long service life. By alloying copper with nickel, the material gains improved mechanical strength and enhanced corrosion resistance while retaining good ductility and workability. Additional alloying elements further improve hardness, weldability, and overall durability, making these alloys suitable for demanding industrial conditions.
At Kalpaturu Piping Solution, we manufacture and supply high-quality Copper Nickel 90/10 Pipe Flanges that are manufactured with precision and tested to meet international standards. These flanges are known for their robust construction, accurate dimensions, and high tensile strength. UNS C70600 Cupro Nickel 90/10 flanges maintain reliable performance even at moderately elevated temperatures, making them ideal for long-term service.
Cupro Nickel 90/10 Slip On, Weld Neck, Threaded, and Socket Weld Flanges are extensively used in valves, pumps, heat exchangers, condensers, and marine piping systems. Their excellent weldability, resistance to stress corrosion cracking, erosion, and hydrogen embrittlement, along with stable mechanical properties at low temperatures, make them a preferred choice for critical applications involving seawater and brackish water.
Flanges play a vital role in connecting pipes, valves, and equipment, allowing easy assembly, maintenance, and inspection of piping systems. Cupro Nickel 90/10 Lap Joint and Ring Type Joint Flanges are especially popular in pressure vessels, desalination plants, evaporators, and brine heaters.
Kalpaturu Piping Solution offers Cupro Nickel 90/10 Flanges in a wide range of sizes, pressure classes, and types, including Blind Flanges, ensuring reliable solutions for diverse industrial requirements.

What are Copper Nickel Flanges?
Copper-nickel alloys, famous because of their high copper content, 10 per cent nickel, and little traces of iron, zinc, lead, and molybdenum, make the alloy immune to erosion and noxious nature, playing an important part in the corrosive environment. Neo Impex Stainless Pvt. Ltd. is a major manufacturer of copper nickel flanges that would be a good substitute in case you want to buy the flanges that are not that expensive but still durable. Copper nickel flanges are made of quality steel stock which is forged. They are forged through heating, forming and cooling. Various forging methods are dependent on the production volume of manufactured items. The open-die drop forging technique is mostly applicable in low-volume products but with a fast production rate. Nonetheless, it takes in large machining allowances.

People Ask About Copper Nickel Flange Manufacturer
Copper-nickel alloys are widely used in applications that require excellent resistance to corrosion, especially in seawater and harsh environments. They are commonly used in marine piping systems, heat exchangers, condensers, desalination plants, offshore platforms, and industrial water systems. Copper-nickel is also preferred for valves, pumps, and flanges because of its durability, resistance to biofouling, and long service life. Its good weldability and strength make it suitable for both low- and high-pressure piping applications.
The three most commonly used types of flanges in piping systems are Weld Neck Flanges, Slip-On Flanges, and Blind Flanges. Weld Neck flanges provide strong, leak-proof connections and are ideal for high-pressure and high-temperature applications. Slip-On flanges are easy to install and cost-effective for low to medium pressure systems. Blind flanges are used to close the end of a pipe, valve, or pressure vessel, allowing for easy inspection and maintenance of the piping system.
Copper nickel flanges are available in a wide range of sizes to suit various industrial and marine piping requirements. Standard sizes typically range from 1/2 inch to 36 inches, depending on the flange type, pressure class, and applicable standards. These flanges are manufactured in accordance with international specifications such as ANSI/ASME, DIN, BS, and EN, ensuring compatibility with different piping systems. Custom sizes and thicknesses can also be supplied to meet specific project or application needs.
