Copper Nickel Flanges
If you need an exceptional and durable flange that is going to have excellent corrosion resistance in water and saline and/or continue to perform under extreme conditions, then Copper Nickel Flange is made for you. As a premium product in the field of Flanges, Copper Nickel Flanges are manufactured using Copper Nickel material and provide an excellent alternative for Marine, Offshore and Desalination industry applications. Riyaarth Overseas offers a wide range of Copper Nickel Flanges manufactured according to industry standards so you can count on them to deliver superior performance over time.
Key Properties of Copper Nickel Flanges
- Resistance to Corrosion – Copper Nickel Flange does not corrode in seawater, acidic conditions or in extreme marine conditions, and is therefore ideal for Marine and Offshore applications.
- Anti-Biofouling – Copper Nickel Flange‘s natural resistance to biofouling means less maintenance and maintains system efficiency.
- Thermal Conductivity – Copper Nickel Flange‘s high thermal conductivity means Copper Nickel Flanges suit heating, cooling and heat transfer applications.
- Long Life and High Durability – Copper Nickel Flange is designed to withstand corrosive environments for an extended period, so you will replace them infrequently.
- Excellent Welding and Forming – Copper Nickel alloy is very easy to weld, providing easy fabrication and flexibility for custom installation.
Types of Copper Nickel Flanges
Copper nickel flanges are available in a variety of alloy compositions and flange designs that can be customised to suit many different applications. The following are some of the most common copper-nickel flanges:
- 90-10 Copper Nickel (C70600): 90% Copper – 10% Nickel – excellent resistance to seawater corrosion, biofouling and stress corrosion cracking. Used primarily in marine & offshore pipe.
- 70-30 Copper Nickel (C71500): 70% Copper – 30% Nickel – greater resistance to both corrosion and erosion, capable of withstanding the demands of high-stress applications, such as those found in high-velocity seawater systems.
Copper Nickel Flange Design Types:
- Slip-On Flanges – The easiest to install and are typically used in lower-pressure applications.
- Weld Neck Flanges – Typically provide additional strength to facilities subjected to higher pressures and are often used in corrosive environments.
- Blind Flanges – These are used to isolate a pipeline from a valve or other piece of equipment.
- Socket Weld Flanges – Allow for secure fittings of small diameter pipes, especially for marine and HVAC applications.
- Lap Joint Flanges – Allow rapid assembly and disassembly, making them ideal for systems requiring regular cleaning and inspections.
- Threaded Flanges – Best used for low-pressure, low-temperature applications when welding is not possible.
Applications of Copper Nickel Flanges
The unique chemical, physical, and a variety of other attributes make copper nickel flanges versatile and used widely in:
- Marine and Offshore: Copper-nickel flanges are essential for marine and offshore piping systems (e.g., shipbuilding and offshore oil platforms) since they are resistant to saltwater corrosion, biofouling, and so on.
- Desalination Plants: Flanges made of copper-nickel are used in water treatment and desalination to prevent corrosion in flanges.
- Industrial Cooling and Heating Systems: Copper nickel‘s high thermal conductivity improves the efficiency and durability of heat exchangers and cooling systems.
- Electric Power Generation: Copper-nickel flanges are often found in condensing systems and applications involving high temperature and pressure.
- HVAC Systems: Copper nickel flanges are excellent for use in HVAC systems, where heat is transferred and humidity and the environment impact the system‘s performance.
Advantages of Copper Nickel Flanges
- Corrosion Resistance: Copper nickel‘s corrosion resistance makes copper nickel flanges perfect for marine and other corrosive applications.
- Biofouling Resistance: Because of its biofouling resistance, the lifespan of copper nickel flanges is significantly longer when compared with most other metals, and the cost–effectiveness and efficiencies associated with this material are not only beneficial to the user, but also to the environment.
- High Heat Conductivity: The thermal conductivity of copper nickel allows efficient transfer of heat to the material being processed, making it extremely efficient for systems that require heating and/or cooling, such as heat exchangers and condensers.
- Ease of Fabrication and Formability: Flanges made of copper nickel can be fabricated and installed quickly and accurately, making it easy to create custom and/or complex flange requirements.
- Durability: Due to the longer life expectancy and lower maintenance costs of copper nickel flanges compared to most other metals, copper nickel flanges are built for long–term use and require a minimal amount of energy to maintain.
