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 pipelines, ballast systems, firefighting systems, shipbuilding.
Offshore & Onshore: Oil and gas platforms, desalination plants, power stations.
Industrial: Heat exchangers, condensers, and equipment requiring resistance to high-velocity seawater corrosion.
3. Product Functions
Connection & Extension: Provides reliable, leak-proof mechanical connection for piping systems.
Access & Maintenance: Blind flanges allow easy access to pipe ends or pressure vessels for inspection and cleaning.
Pressure Isolation: Isolates specific sections of a piping system without draining the entire system.
Size & Direction Change: Facilitates changes in pipe diameter (reducing flanges) or direction when combined with fittings.
