To suit the different needs of the clients, our Cupronickel Alloy Tubes are available in varied sizes. Anti corrosive nature, non abrasive property and high durability are some of the salient features of our Cupronickel Alloy Tubes. We stand as the prospering Cupronickel Tubes Supplier in India.
Characteristics
A Copper Nickel alloy having small amount of iron and manganese to improve corrosion resistance in high velocity (from 1 to about 4 mtrs/sec.) waters, including sea water. The alloy is relatively insensitive to stress corrosion. It has good cold and hot working properties and is readily weld able.
Guide to the selection of tube material:
Sea Water
Dissolved salts from 10000 ppm.
Absence of abrasive suspended solids.
Polluted with H2S and Ammonia.
Permissible average velocity of water 3 – 4 meters/sec
