Product Description
ISO 1635 CuNi5Fe1MN 95/5 Copper Nickel
Cupro Nickel 95/5 Heat Exchanger Tubing is one of the best equipment formed with copper and nickel alloy. The heat exchanger/ condensor exhibits superior resistance towards brackish water, atmospheric and non-oxidizing acid corrosion circumstances. These copper-nickel alloys possess outstanding resistance to stress corrosion cracking and crevice corrosion. Even more, it also offers good thermal stability and moderate strength at elevated temperature. These heat exchangers/condensor allows superior resistance to sea water corrosion.
Exceptional Resistance for Marine EnvironmentsCuNi5Fe1Mn 95/5 Copper Nickel alloys, standardized by ISO 1635, excel in marine engineering due to their superior resistance to seawater corrosion. Their robust composition makes these tubes ideal for desalination plants, offshore installations, and any application requiring durability against harsh aquatic conditions.
Versatile Manufacturing and Customization OptionsThese copper nickel tubes are produced using techniques such as extrusion, cold working, and annealing, ensuring reliable mechanical properties and consistent quality. Custom sizes, wall thicknesses, and finishesplain, beveled, or threadedare available to meet specific project requirements.
Reliable Performance at High TemperaturesEngineered to operate steadily at temperatures up to 300C, CuNi5Fe1Mn tubes maintain a minimum tensile strength of 240 MPa and elongation up to 35%, ensuring safety and reliability in heat exchangers and other high-temperature environments.
FAQs of ISO 1635 CuNi5Fe1MN 95/5 Copper Nickel:
Q: How does ISO 1635 CuNi5Fe1Mn 95/5 Copper Nickel resist seawater corrosion?
A: Thanks to its balanced composition of 95% copper, 5% nickel, and additions of iron and manganese, this alloy forms a passive protective layer on its surface, granting excellent resistance to corrosion and biofouling in seawater, making it a preferred material in marine and offshore applications.
Q: What are the main applications for CuNi5Fe1Mn copper nickel tubes?
A: These tubes are extensively used in marine engineering, desalination facilities, offshore structures, and heat exchangers due to their mechanical strength, seawater corrosion resistance, and ability to function reliably under high temperature and pressure.
Q: When should I choose seamless versus welded copper nickel tubes?
A: Seamless tubes are ideal for high-pressure and critical environments because they provide higher integrity and uniformity, while welded tubes are cost-effective for non-critical applications with moderate operating conditions.
Q: Where are these copper nickel tubes typically exported from?
A: As a leading exporter, manufacturer, and supplier based in India, these tubes are shipped globally, and packaging options such as sturdy wooden boxes or bundles ensure safe transit to your location.
Q: What processes are involved in the manufacturing of these tubes?
A: Depending on the required specifications, the tubes undergo extrusion, cold working, and annealing. Surface treatments like pickling and annealing help achieve the desired mechanical properties and a clean metallic finish.
Q: How can these copper nickel tubes benefit heat exchanger operations?
A: With excellent thermal conductivity, mechanical stability, and corrosion resistance, these tubes optimize heat transfer efficiency and extend the service life of heat exchangers in seawater cooling and process industries.
Q: What custom size options are available for copper nickel tubes?
A: Custom sizes are offered in inside diameters (6104 mm), outer diameters (8108 mm), wall thicknesses (17 mm), and lengths up to 6 meters, allowing for precise adaptation to specific installation or design requirements.
