Corrosion Types and Measures for Petrochemical Equipment

The corrosion problem of petrochemical equipment has always been one of the important factors restricting industrial development. Starting from the basic concept of corrosion, this article delves into various forms of corrosion in petrochemical equipment and their impact on equipment performance. Chemical corrosion, high-temperature corrosion, microbial corrosion, and stress corrosion are common forms of corrosion in petrochemical equipment, exacerbating equipment aging and wear. For different forms of corrosion, existing anti-corrosion measures include material selection, coating protection, electrochemical protection, etc. However, these measures also face certain limitations and challenges in practical applications. In summary, this article deeply analyzes the corrosion problem of petrochemical equipment, summarizes the limitations of existing anti-corrosion measures, and explores key measures to improve the anti-corrosion performance of petrochemical equipment. These research results are expected to provide useful references for equipment maintenance and safe operation in the petrochemical industry, and contribute to solving corrosion problems and improving equipment service life.
