What are the aspects of process corrosion protection in oil refining companies?

Corrosion prevention management is a comprehensive management practice. For reference, please see the Management System for Corrosion Prevention of Petrochemical Equipment: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=23906&shareuid=301199

Process corrosion prevention in petroleum refining enterprises involves the following aspects: 1. Material selection: Corrosion- and heat-resistant materials such as stainless steel and nickel-based alloys should be selected to minimize the likelihood of corrosion in equipment and pipelines. 2. Corrosion-resistant coatings: Corrosion-resistant coatings such as epoxy coatings and polyester coatings are applied to the surfaces of equipment and pipelines to provide a physical barrier and chemical protection. 3. Corrosion protection layer inspection: Regularly inspect the corrosion protection layers of equipment and pipelines to ensure their integrity and corrosion resistance. 4. Anti-corrosion measures: Special anti-corrosion measures should be taken for equipment and pipelines that are severely affected by corrosive substances, such as applying anti-corrosive coatings or injecting corrosion inhibitors. 5. Cleaning and rust prevention: Regularly clean and apply rust prevention measures to equipment and pipelines in order to remove dirt, impurities, and corrosion products, thereby reducing the likelihood of corrosion. 6. Monitoring and maintenance: Establish an effective monitoring system to conduct regular inspections and maintenance of equipment and pipelines, so as to identify and repair corrosion issues promptly and extend the lifespan of the equipment. Please note that the above information is only general advice; specific anti-corrosion measures for the processing process must be determined based on the actual conditions and requirements of the petroleum refining enterprise. .

Century Pastoral, those things of yours are not related to anti-corrosion craftsmanship at all.

Inject corrosion inhibitor, inject water, use corrosion probes; regularly analyze the pH and iron ions in acidic water
