Corrosion Resistance: Copper Nickel 90/10 is highly resistant to seawater corrosion, making it ideal for marine applications. This resistance extends to a variety of other acidic and alkaline hotspots.
High Strength: Copper Nickel 90/10 has excellent mechanical properties, including high strength and durability, allowing it to withstand high stresses without corrosion or failure.
Temperature stability: The alloy maintains its mechanical properties over a wide range of temperatures, making it suitable for both high and low temperatures with minimal loss of performance
Biofouling Resistance: Copper Nickel 90/10 prevents the growth of barnacles, algae and other marine organisms due to its natural properties, reducing the need for frequent maintenance and cleaning in marine environments.
Easy to manufacture: Copper Nickel 90/10 is relatively easy to work with conventional manufacturing processes such as welding, brazing, and soldering, allowing complex components, including flanges, to be manufactured without den completely.
Since Copper Nickel 90/10 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 90/10 flanges are widely used in marine environments due to their resistance to seawater. They are used on ships, offshore oil refineries, desalination plants, and other marine structures.
Piping systems: These flanges are used in piping systems where corrosion resistance is required, such as seawater piping, saltwater cooling systems, and hydraulic systems
Chemical Applications: Corrosive chemical companies typically use copper-nickel 90/10 flanges in their reactors, reactors and pipelines
Power supply: Copper-nickel 90/10 flanges are used in electrical equipment, especially those in offshore areas in heat exchangers, condensers and other applications containing seawater or brackish water
Desalination equipment: Copper-nickel 90/10 flanges are commonly found in desalination plants that treat seawater as fresh water. It is used in piping, pumps, valves and other applications.
Yes, Copper Nickel 90/10 flanges are weldable using standard welding techniques such as gas tungsten arc welding (GTAW) or gas metal arc welding (GMAW). However, it’s essential to use proper procedures and filler materials compatible with copper nickel alloys to maintain corrosion resistance and mechanical properties.
Maintenance for Copper Nickel 90/10 flanges primarily involves periodic inspection for signs of corrosion or damage. Clean with fresh water regularly to remove deposits. In harsh environments, consider protective coatings. Monitor for leaks and ensure proper sealing integrity. Follow manufacturer guidelines for specific maintenance recommendations.
Copper Nickel 90/10 flanges are environmentally friendly due to their high recyclability, long lifespan, and resistance to corrosion, reducing the need for frequent replacements. Additionally, copper nickel alloys are non-toxic and do not pose environmental hazards during use or disposal, making them eco-friendly choices for various applications.
Copper Nickel 90/10 flanges may not be ideal for hygienic and sanitary applications due to their tendency to develop tarnish, which can compromise surface cleanliness. Stainless steel or other materials with smoother surfaces and better resistance to tarnishing are typically preferred for such applications to maintain strict hygiene standards.
