ASME B16.5 CuNi 70/30 SW Flange Class150, Forged RF Copper Nickel Alloy C71500
ASME B16.5 CuNi 70/30 SW Flange Class150, Forged RF Copper Nickel Alloy C71500
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
