Cupro Nickel Finned Tube

Cupro-Nickel Fin Tubes are processed out of plain Cupro-Nickel Tubes conforming to SB-111 UNS No. 70400, 70600, 71000, 71500 and finning will be carried out as per SB-359. 90:10 Cupro-Nickel exhibits excellent resistance to impingement attack. This alloy is suitable for Marine condenser tubes, especially where higher water velocities are encountered.70:30 Cupro-Nickel has in general, the best resistance of any of the copper alloys to impingement attack and to corrosion from most acids and waters. It is being used in severe corrosive conditions in which service lives longer than those of other copper alloys are desired. These fin tubes are manufactured out of Cupro-Nickel tubes of Minimum 9.52mm OD up to 25.40mm OD. Wallthickness of the plain tubes varies from 1.21mm upto 2.77mm, depending upon the technical Parameters, required by customer.
