Copper Nickel 70/30 Flange Manufacturer in India

Nitech Stainless Inc is a leading Copper Nickel 70/30 Flange Manufacturer in India. Copper Nickel 70/30 flanges are made from a copper-nickel alloy consisting of approximately 70% copper and 30% nickel, with small additions of other elements like iron and manganese. This particular alloy is highly regarded for its excellent resistance to corrosion, particularly in seawater and other harsh marine environments, making it ideal for use in marine, offshore, and shipbuilding applications. Copper Nickel 70/30 flanges are also known for their good strength, durability, and resistance to biofouling, which is the accumulation of microorganisms, plants, and animals on submerged surfaces. These flanges are often used in piping systems that transport seawater, brine, and other corrosive fluids, ensuring secure and leak-proof connections under pressure. The alloy's ability to withstand galvanic corrosion (where metals in contact with each other corrode due to electrochemical reactions) makes Copper Nickel 70/30 flanges particularly valuable in marine and chemical processing industries. Available in various types like slip-on, weld neck, and blind, these flanges are suitable for high-performance systems requiring corrosion resistance and long-term reliability in challenging environments.
