The reason why stainless steel heat exchangers are highly resistant to corrosion

Fin tube stainless steel heat exchangers are efficient heat exchange equipment in the field of modern engineering applications. They are suitable for heating, cooling and sterilizing various liquids that are non-corrosive to stainless steel. They are widely used in environmental protection, food, dairy products, beverages, chemistry and medicine.

Fin tube stainless steel heat exchangers are available in single-stage and multi-stage forms. The heat exchange area ranges from 0.5-100 ㎡ in various specifications, and can be supplemented by PLC automatic control to meet the one-time completion of the heating, cooling, sterilization and heat exchange process.

The process design and manufacturing can be carried out according to the customer’s use requirements.

The reason why Fin tube stainless steel heat exchangers are highly resistant to corrosion is mainly due to the excellent corrosion resistance of stainless steel itself and its advantages in heat exchanger design and material selection. ‌

The reason why Fin tube stainless steel has excellent corrosion resistance is mainly due to the chromium and molybdenum elements in its composition.

When the chromium content reaches 12%, a stable, transparent, and very thin passivation film can be spontaneously formed in the atmosphere or in an oxidizing medium to prevent corrosion and basically not rust.

Molybdenum can increase the strength of the passivation film on the surface of stainless steel, improve resistance to chloride stress corrosion cracking, enhance local corrosion resistance, and reduce problems such as pitting and crevice corrosion.

These characteristics make stainless steel perform well in various corrosive environments.

In the design and material selection of heat exchangers, stainless steel U-shaped tubes are ideal for the main components of heat exchangers due to their excellent corrosion resistance, high strength and toughness, good thermal conductivity, and easy cleaning and maintenance.

The shape of stainless steel U-shaped tubes is compact, space-saving, and conducive to the miniaturization and lightweight design of heat exchangers.

The strong corrosion resistance of stainless steel heat exchangers is due to the excellent corrosion resistance of stainless steel itself and its advantages in design and material selection. These characteristics together ensure the stability and long-term use of stainless steel heat exchangers in various environments.
