Copper Nickel Tube Heat Exchanger

A copper nickel tube heat exchanger is a type of heat exchanger that uses tubes made from a copper-nickel alloy to transfer heat between two fluids. These heat exchangers are commonly used in various industries, especially in marine environments where corrosion resistance is essential.

Copper-nickel alloys are known for their excellent corrosion resistance, especially in seawater environments. The most common copper nickel alloy used in heat exchangers is CuNi 90/10 (90% copper, 10% nickel) or CuNi 70/30 (70% copper, 30% nickel). These alloys offer good thermal conductivity along with their corrosion resistance.

Applications:

Marine Industry: One of the primary applications of copper nickel tube heat exchangers is in the marine industry, particularly for cooling or heating systems on ships and boats. The resistance to seawater corrosion makes them ideal for these environments.

Offshore and Coastal Installations: Similar to marine applications, offshore platforms and coastal installations benefit from the corrosion resistance of copper nickel tubes in their heat exchangers.

Desalination Plants: In desalination processes, where seawater is converted into freshwater, copper nickel heat exchangers are used to transfer heat during various stages of the process.

Chemical Industry: Certain chemical processes require heat exchange, and the corrosion resistance of copper nickel makes them suitable for these applications where aggressive chemicals are involved.
