Corrosion resistance: The Copper Nickel 70/30 alloy offers exceptional resistance to corrosion from seawater, which makes it well suited for marine uses. This resistance comes from the creation of a protective oxide layer on its surface, which stops further deterioration.
High Strength: The Copper Nickel 70/30 alloy retains solid strength even at high temperatures, enabling it to endure both high pressures and elevated temperatures
Ductility: This alloy is ductile, meaning it can be readily assembled and formed into a range of shapes, such as flanges, without sacrificing its mechanical properties
Thermal Stability: Copper Nickel possesses outstanding thermal stability of 70/30, which makes it appropriate for typical applications where temperature swings frequently occur
Biocompatibility: The alloy is non-toxic and biocompatible, which makes it appropriate for uses that involve contact with living tissue, such as medical devices and implants
Because Copper Nickel 70/30 Flanges possess outstanding mechanical properties and stand up to wear corrosion and high temperatures, they see broad use across numerous industries. These flanges are commonly applied in the oil and gas, petrochemical, power generation, and aerospace sectors. They serve a key role in connecting equipment, valves, and piping systems. Thanks to their remarkable strength, toughness, and resistance to wear, they are ideal for uses subjected to harsh operating conditions, including high temperatures, elevated pressures, and corrosive surroundings.
Marine applications: Copper-nickel 70/30 flanges see extensive use in marine settings thanks to their ability to withstand seawater. They serve applications in shipbuilding, offshore platforms, and desalination plants.
Chemical applications: These flanges find application in the chemical sector wherever corrosion resistance is needed. They also feature in piping systems that carry corrosive fluids like acids and alkalis.
Oil and Gas Industry: Within the oil and gas sector, copper-nickel 70/30 flanges serve in pipelines and offshore structures where resisting corrosion and erosion from seawater is essential
Power generation: These flanges are employed in power plants, particularly within steam circulation systems, steam generators and heat exchangers, offering strong heat transfer and corrosion resistance
Desalination equipment: Copper-nickel 70/30 flanges are frequently applied in desalination equipment for pipelines and heat exchangers owing to their resistance to seawater corrosion
Understanding Application Requirements: Identify the particular use case that requires the flange. Take into account elements like pressure, temperature, resistance to corrosion, and how well it works alongside other parts within the system.
Composition: Copper Nickel 70/30 consists of 70% copper and 30% nickel, along with minor quantities of additional elements. Familiarize yourself with what this product offers, such as its resistance to corrosion, moisture and biofouling, which makes it appropriate for marine and other demanding conditions.
Flange Standards and Specifications: Verify the standards and specifications your application calls for. Confirm that flanges meet international benchmarks like ASTM B466 for fittings and ASTM B151 for plates, sheets and strips.
Size and Pressure Evaluation: Using the requirements of your application, establish the flange dimensions and the necessary pressure rating. Since flanges are available in a range of sizes and pressures, select the option that fits your system’s needs best.
End connections: Think about the kind of end connections your system requires, whether socket welded, threaded, or flanged ends. Confirm that it works well with the other parts of the system.
