Product Description
ASME B16.5 CuNi 70/30 Forged Flange, Class150 SW Long Life Anti-Biofouling
1.Product Description
The Copper Nickel Flange is a high-performance pipe connecting component manufactured from Copper-Nickel alloy (typically 90/10 or 70/30 composition). It is widely used to connect pipes, valves, pumps, and other equipment to form a complete and reliable piping system. Thanks to its excellent resistance to seawater corrosion, this flange has become the industry standard in marine engineering and offshore oil & gas applications.
2. Applications
-
Marine Engineering: Seawater cooling systems, ballast water lines, firefighting piping, ship hull piping.
-
Offshore & Onshore: Oil & gas platforms, desalination plants, coastal power stations.
-
Industrial Equipment: Heat exchangers, condensers, evaporators, and any equipment requiring resistance to high-velocity seawater or brackish water corrosion.
3. Product Functions
-
Reliable Connection: Provides a robust, leak-tight mechanical joint between pipe sections or between pipes and equipment.
-
Easy Maintenance Access: Blind flanges allow rapid opening of pipe ends or pressure vessels for internal inspection, cleaning, or repair.
-
System Isolation: Isolates specific sections of a piping system for maintenance or emergency repair without draining the whole system.
-
Size Transition & Direction Change: Reducing flanges enable diameter changes; when combined with elbows or tees, they facilitate flow direction changes.
