copper nickel and brass tube

Copper nickel heat exchanger tube indicates the cupronickel tube applied in heat exchanger which is a device used to transfer heat between two or more fluids. In other words, heat exchangers  are used in both cooling and heating processes. Cupronickel tube is used in heat exchanger due to some essential properties of corrosion resistance, good tensile strength, excellent ductility when annealed, thermal conductivity  and expansion characteristics amenable for heat exchanger and condenser.
