Copper Nickel Tube 90/10

90/10 Copper Nickel Tubes Tube is widely used in sea water. It has very good corrosion resistance to clean or moderately polluted marine or estuary water, even containing dissolved incondensable gases.

This alloy is virtually immune from stress-corrosion cracking and hot spot denickelification. In clean sea water, velocities of up 2,2-2,5 m/s (7,5-8,5 ft/s) are accepted while 4 m/s (13 ft/s) is the upper limit for clean fresh or slightly saline solutions.

To avoided the risk of deposit attack, it is generally recommended to never operate at water velocities below about 0,8-1 m/s (2,5-3,5 ft/s). 90/10 Copper Nickel Tubes can also be used, with appropriately reduced flow velocity, in contact with water containing some sulphides or suspended solids. It is also often selected for its good mechanical properties, both at room and relatively elevated temperatures.
