Please compare the advantages and disadvantages of enamel reactors and stainless steel reactors based on production and practical usage experience. Thank you!

Enameled reactors are generally used to handle acidic and alkaline media, but they cannot withstand high temperatures; they are suitable for use below 50°C and not appropriate as reaction vessels, though they can be used as neutralization containers. Stainless steel reactors, on the other hand, have specific requirements regarding the types of media they can handle – they cannot be used in processes that are corrosive to steel, such as those involving compounds rich in chlorine molecules, as these will cause slow corrosion of the stainless steel

Disadvantages: Hydrofluoric acid at any concentration, as well as fluoride ions, are harmful to it. The designed operating temperature is 200 degrees; in actual use, it is better to maintain a lower temperature of 180 degrees. Impact from thermal and cold loads has a significant effect on it. Phosphoric acid also has a significant impact

Corrosion resistance: Enamel-lined equipment boasts excellent corrosion resistance and can withstand many strong acids and bases. 2. Surface roughness: The enamel surface is smooth and easy to clean, making it particularly suitable for applications in the pharmaceutical and fine chemical industries where high cleanliness is required; the surface finish can be 10 times better than that of stainless steel. 3. Disadvantages: Enamel-lined tanks require strict adherence to relevant regulations at every stage, from design and manufacturing to lifting, transportation, installation, and use. They are delicate products that need careful handling. Users without experience may damage them due to improper operation. The quality of products manufactured by domestic enamel manufacturers varies greatly, and ordinary buyers often lack the expertise to distinguish between high-quality and low-quality enamel products. Stainless steel reactors have a longer service life.
