manufacturer And supplier Of EN 1092-1 70/30 Copper Nickel Weld Neck And Blind Flanges In Mumbai, India


Copper Nickel 70/30 Flanges

Copper Nickel 70/30 Flanges are made up of copper and nickel alloy that contains 70% copper and 30% nickel. These flanges are resistant to erosion and corrosion due to the addition of manganese and iron. These flanges offer resistance to corrosion in saltwater and marine environments. As per 70/30 Copper Nickel Weld Neck Flanges Manufacturer In India, they are resistant to salts, brine water, organic compounds, and diluted non-oxidizing. These flanges feature good tensile strength, toughness, and hardness. They also provide good weldability, castability, and ductility.

70/30 Copper Nickel Blind Flange offered by us are cold worked and fabricated. They also offer resistance to attack by steam and fresh water and are subject to biofouling at low temperatures. Cupro Nickel- 70:30 Threaded Flanges also resist dry and wet chlorine and CO2 at ambient temperature. They also offer corrosion resistance in polluted seawater and high velocity areas. Werkstoff Nr.2.0882 Plate Flanges also sustain attacks of sulfuric, mild organic, and phosphoric acid. They are also resistant to pitting and crevice corrosion in marine environments. 

Cu Ni 70 30 C71500 Copper Nickel Lap Joint Flange is manufactured by hot or cold forging and can display thermal stability in high temperatures. These flanges are used in marine environments and are said to be expensive due to the elements used in them. C71500 Cu Ni Threaded Flanges do not require any special material for fabrication. It has a melting point of 2260 degrees C. They are produced as per international standards and are passed through various tests before supplying them to the customer. This ensures that Copper Nickel Cu-Ni 70/30 (C71500) Pipe Flanges have inherited the desired property. If required they can also be customized as per the requirement of the customers.
