Copper Nickel 70/30 Welding Neck Flanges

Rexino Stainless & Alloys are one of the leader Supplier and exporters of high quality Copper Nickel 70 / 30 Flanges . C71500 Copper Nickel 70/30. Cupro nickel or copper-nickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. We are supplies C71500 Copper Nickel, also known as 70/30 Copper Nickel which is mainly used for oil & gas and marine defense applications. the corrosion resistance of Copper Nickel 70 / 30 Flanges(UNS C71500) is particularly enhanced in polluted seawater and soaring-velocity waters. A flange is a way of joining pipes, valves and pumps to form a piping system and are usually welded or screwed. These Copper Nickel 70-30 Socket Weld Flanges are made using high-end technology and latest machinery

Cu-Ni 70 / 30 Weld Neck Flanges, Copper Nickel C71500, as well-known as 70/30 Copper Nickel, provides good corrosion resistance, particularly in marine saltwater atmospheres. They as well have significant embellishments of Manganese and Iron which are essential to preserveexcellent corrosion resistance. CuNi 70/30, Copper nickel offers excellent corrosion resistance, especially in marine salt water environments. Copper nickel alloys comprise 2 to 30% nickel and have high oxidation resistance and stress corrosion cracking resistance.
