Copper Nickel Flanges

Cu-Ni Flanges

The impermeability to erosion and noxiousness of Copper Nickel Alloys, which are famous for their high Copper content and 10% Nickel as well as trace amounts of Iron, Zinc, Lead, and Molybdenum, enable them to play a crucial role in corrosive environments. If you’re searching for reasonably priced yet sturdy flanges, Shree Viratra Enterprises is a top manufacturer of Copper Nickel Flanges. High-quality steel stock is used to forge Copper Nickel Flanges. They are heated, formed, and cooled as part of the forging process. Different forging techniques are employed depending on the manufacturing volume. Although it has a high production rate, the open-die drop forging technique is frequently utilized for low-volume goods. But it necessitates large machining allowances. There are numerous applications for copper nickel forged fittings and flanges. They can be utilized for high-pressure pipework and in maritime conditions. Shipbuilding also employs these flanges. Their socket weld flanges with 90/10 copper and nickel are frequently utilized in small-size, high-pressure pipe applications. Although they are made to withstand higher pressures, they provide the same static and fatigue strength as Slip On SORF Flanges. A good conductor of heat and electricity is copper nickel. Therefore, it is frequently employed in marine applications. For applications where high pressure is required, it is the best option. There are several grades and sizes of copper-nickel flanges available. Systems for transporting seawater are typical applications. They have excellent endurance and have a high level of corrosion resistance. They are perfect for use in the chemical, oil, and gas sectors and have a high level of wear and tear resistance. These flanges come in anodized or powder-coated finishes and can also be specified in custom lengths. They are ASTM compliant and frequently offered for same-day delivery.
