Copper nickel cooling tube indicates the cupronickel tube applied in seawater cooling. The traditional process of seawater cooling is distillation, which is boiling and re-condensation of seawater to leave salt and impurities behind. Due to its energy consumption, cooling seawater is generally more costly than fresh water from rivers or groundwater, water recycling and water conservation. However, these alternatives are not always available and depletion of reserves is a critical problem worldwide, Cupronickel tube is used in seawater cooling for its features of corrosion resistance, good thermal conductivity, ductility at cryogenic temperatures and beneficial antimicrobial touch surface properties etc.
