1.Product Description
The Copper Nickel Flange is a high-performance piping component manufactured from Copper-Nickel alloy (commonly 90/10 or 70/30 composition). It is designed to connect pipes, valves, pumps, and other equipment to form a complete piping system. Due to its excellent resistance to corrosion in marine environments, this flange is the industry standard for naval architecture and offshore engineering.
2. Applications
Marine Engineering: Seawater cooling lines, ballast systems, firefighting systems, and shipbuilding .
Offshore & Onshore: Oil and gas platforms, desalination plants, and power generation stations .
Industrial: Heat exchangers and condensers where resistance to corrosion by high-velocity seawater is critical
3. Product Functions
Marine Engineering: Seawater cooling lines, ballast systems, firefighting systems, and shipbuilding.
Offshore & Onshore: Oil and gas platforms, desalination plants, and power generation stations.
Industrial: Heat exchangers and condensers where resistance to high-velocity seawater corrosion is critical.
