01 What are Copper Nickel 90/10 flanges?

Copper Nickel 90/10 flanges are pipe fittings made from an alloy containing 90% copper and 10% nickel. They are used to connect pipes and components in piping systems, especially in corrosive environments like marine and offshore settings.

  • Corrosion Resistance: Excellent resistance to seawater and saline environments.
  • aDurability: High strength and toughness suitable for various pressure and temperature conditions.
  • Thermal Conductivity: Good thermal conductivity, ideal for heat exchangers.
  • Ease of Fabrication: Easy to fabricate and weld, providing design flexibility.

Minimal maintenance is needed due to their corrosion-resistant properties. Regular inspections for mechanical integrity and occasional cleaning to remove surface deposits are usually sufficient.

These flanges are manufactured to meet various international standards such as ANSI, ASME, ASTM, and DIN, ensuring high quality and compatibility with other piping components.
