Difference Between Stainless Steel And Nickel Alloy Heat Exchanger Tubes

Stainless steel and nickel alloy heat exchanger tubes are common materials in heat exchange equipment, and they both have a wide range of applications in the field of heat exchange. Although they are both pipes used to conduct heat, there are obvious differences in material composition, performance characteristics and application areas.

Stainless steel is a steel with good corrosion resistance, the main components include iron, carbon and at least 10.5% chromium. The corrosion resistance of this material mainly comes from chromium, and a dense chromium oxide film formed on the surface effectively prevents further oxidation, so it is widely used in the fields of food processing, medical equipment, architectural decoration and so on.

When comparing the two, stainless steel heat exchanger tubes are commonly used for heat exchange in general industrial and residential equipment due to their cost-effectiveness and good thermal conductivity. Nickel alloy heat exchanger tubes, on the other hand, are more suitable for high temperature, high pressure and strong corrosive environments due to their stability under extreme conditions, especially when dealing with high-temperature corrosive fluids where the advantages are more obvious.

Nickel alloy heat exchanger tubes: mainly used in petrochemical, aerospace, marine engineering and other high-end areas, the working environment in these areas is extremely harsh, requiring materials with high corrosion resistance and high temperature resistance.
