We offer These Copper Nickel 70/30 Flanges as per DIN, ISO, JIS or ANSI Standard.
Corrosion resistance: Copper Nickel 70/30 alloy is highly resistant to seawater corrosion, making it ideal for marine applications. This resistance is due to forming a protective oxide layer on its surface, preventing further degradation.
High Strength: Copper Nickel 70/30 alloy maintains good strength even at elevated temperatures, allowing it to withstand high pressures and high temperatures
Ductility: This alloy is ductile, i.e. it is easily assembled and manufactured in various shapes, including flanges, without losing its mechanical properties
Thermal Stability: Copper Nickel has an excellent thermal stability of 70/30, making it suitable for common applications where temperature fluctuations are common
Biocompatibility: The alloy is non-toxic and biocompatible, making it suitable for use where contact with living tissue is required, such as medical devices and implants
Since Copper Nickel 70/30 Flanges have excellent mechanical qualities and are resistant to wear corrosion, and high temperatures, they are widely used in various industries. These flanges are widely used in the oil and gas, petrochemical, power generation, and aerospace industries. They play an important part in joining equipment, valves, and pipe systems. They are perfect for applications exposed to severe operating conditions, such as high temperatures, high pressures, and corrosive environments, because of their exceptional strength, toughness, and wear resistance.
Marine applications: Copper-nickel 70/30 flanges are widely used in marine environments due to their resistance to seawater. They are used in shipbuilding, offshore platforms, and desalination plants.
Chemical applications: These flanges are used in the chemical industry where corrosion resistance is required. They are also used in piping systems to transport corrosive liquids such as acids and alkalis.
Oil and Gas Industry: In the oil and gas industry, copper-nickel 70/30 flanges are used in pipelines and offshore structures where it is necessary to resist corrosion and erosion by seawater
Power generation: These flanges are used in power plants, especially in steam circulation systems, steam generators and heat exchangers, with good heat transfer and corrosion resistance
Desalination equipment: Copper-nickel 70/30 flanges are commonly used in desalination equipment for pipelines and heat exchangers due to their resistance to seawater corrosion
Understanding Application Requirements: Determine the specific application for which you need the flange. Consider factors such as pressure, temperature, corrosion resistance, and compatibility with other components in the system.
Composition: Copper Nickel 70/30 is 70% copper and 30% nickel, with small amounts of other elements. Understand the properties of this product, including resistance to corrosion, moisture and biofouling, making it suitable for marine and other harsh environments.
Flange Standards and Specifications: Check the standards and specifications required for your application. Ensure that flanges conform to international standards such as ASTM B466 for fittings and ASTM B151 for plates, sheets and strips.
Size and Pressure Evaluation: Based on application requirements, determine the flange size and required pressure level. Flanges come in various sizes and pressures, so choose the one that best suits your system’s needs.
End connections: Consider the type of end connections necessary for your system, such as socket welded, threaded, or flanged ends. Make sure it is compatible with other elements of the system.
Yes, Copper Nickel 70/30 flanges are weldable using common welding techniques such as TIG (Tungsten Inert Gas) welding, MIG (Metal Inert Gas) welding, and shielded metal arc welding (SMAW). However, it’s essential to follow proper welding procedures and use compatible filler metals to maintain the alloy’s corrosion resistance.
Copper Nickel 70/30 flanges require periodic inspection for corrosion and wear, particularly in marine environments. Regular cleaning with a non-abrasive solution helps maintain surface integrity. Application of anti-seize compounds during assembly can prevent galling. Ensure tightness of bolts and gaskets to prevent leaks.
Copper Nickel 70/30 flanges are considered environmentally friendly due to their high resistance to corrosion in marine environments, reducing the need for frequent replacements and minimizing environmental impact. Additionally, copper is highly recyclable, further enhancing its eco-friendliness and sustainability.
Copper Nickel 70/30 flanges are generally not recommended for hygienic and sanitary applications due to the potential for copper ion leaching, which can affect product purity. Stainless steel or other non-reactive materials are preferred in industries such as food, pharmaceuticals, and biotechnology where strict hygiene standards are essential.
