Product Description
70/30 Copper Nickel

70/30 Copper Nickel Tube is mainly preferred when the severity of service condition (Cooling water, steam, condensate, temperature, etc.) is such as to virtually rule out all other coppermetals. Due to its hardness and to the type of oxide whereby its surfaced is self-protected, 70/30 Copper Nickel Tube has excellent resistance to impingement and erosion-corrosion by of suspended solids in sea water flowing at up to 3-3, 5 m/s (10-11, 5 ft /s). Like all Copper-nickels, 70/30 Copper Nickel Tube is virtually immune from stress-corrosion cracking. It can be very sensitive to deposit attack and is therefore not recommended for stagnant or slowmoving (under 1 – 1,2 m/s or 3,5-4 ft/s) water.





70/30 Copper Nickel is very widely employed in water desalination plants, especially in the most critical areas such as the heat reject and brine heater stages, as well as in the undercooling areas of power station condenser tubes, in the chemical, petrochemical and food processing industries and, more generally, in all applications where top corrosion resistance is required from both the shell and tube side.
