C71500 Cupro Nickel Forged Flange Class150, Socket Weld ASME B16.5 Marine Use
C71500 Cupro Nickel Forged Flange Class150, Socket Weld ASME B16.5 Marine Use
1.Product Description
The Copper Nickel Flange is a high-performance piping component manufactured from a 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. It combines the strength of steel with the corrosion resistance of copper, offering a long service life in aggressive water conditions .
.
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
The Copper Nickel Socket Weld Flange serves the following functions in piping systems:
Pipe Connection: Provides a reliable, leak-proof connection between pipes, valves, pumps, and other equipment
System Access Point: Allows for easy disassembly and maintenance of piping systems
Pressure Containment: Safely contains system pressure up to Class 150 rating
Flow Direction Control: Facilitates changes in piping direction when used with elbows or tees
Equipment Isolation: When used with blind flanges, can isolate sections of the piping system
