CuNi 70/30 Seamless Pipe ASME SB111 C70600 Marine Grade for Heat Exchanger
1. Product Description
Copper nickel pipe is a seamless or welded tube based on copper with nickel as the primary alloying element. Typical grades are C70600 (CuNi10Fe1Mn, i.e., 90/10) and C71500 (CuNi30Fe1Mn, i.e., 70/30). This alloy is widely used in marine, power, and chemical industries, offering a good balance between strength and corrosion resistance.
2.Product Applications
Shipboard ballast, cooling, fire fighting and fresh water piping systems
Heat exchanger tube bundles in desalination plants
Process piping on offshore oil platforms
Condensers and feedwater heaters in power plants (nuclear & thermal)
Corrosion-resistant medium transfer in chemical industry
3.Product Functions
Safely convey seawater, fresh water, oil, gas and mild acidic media
Achieve efficient heat transfer in heat exchangers
Withstand high working pressure (design pressure up to 6.4 MPa and above)
Inhibit marine microorganism adhesion and growth on the inner pipe wall
