Copper Nickel 90/10 Flanges (Cu-Ni 90/10) are highly reliable piping components designed for seawater, marine, and offshore applications where resistance to corrosion, erosion, and biofouling is essential. Manufactured in accordance with ASTM B151 UNS C70600, these flanges combine durability with excellent mechanical strength, making them an ideal choice for critical piping systems. Available types include Blind Flange, Slip On Flange, and Weld Neck Flange, each engineered to meet international standards and ensure long service life in harsh environments.
1.Superior Corrosion Resistance: The 90/10 copper-nickel alloy (90% copper, 10% nickel, with small additions of iron and manganese) provides outstanding resistance against seawater corrosion, stress cracking, and pitting.
2.High Strength & Toughness: ASTM B151 UNS C70600 flanges exhibit good mechanical properties at both ambient and elevated temperatures.
3.Excellent Fabricability: Easy to machine, weld, and install in piping systems, reducing overall project costs.
4.Versatile Applications: Widely used in shipbuilding, desalination plants, offshore oil platforms, power generation, and chemical processing industries.
5.Standard Compliance: Produced according to ASTM, ASME, and EEMUA standards, ensuring compatibility and reliability.
