How to effectively address corrosion and protection of petrochemical heat exchangers?
Thread Content
Heat exchangers are one of the key pieces of equipment in the petrochemical industry; approximately 60% of the numerous daily failures and emergency repairs are caused by corrosion and leakage in the tubes of these heat exchangers. Additionally, some tube bundles are prone to scaling, resulting in a decrease in heat exchange efficiency. Therefore, the proper selection of tube bundle materials and corrosion prevention methods has always been a matter of great concern to us. What methods can be used to extend the service life of heat exchangers?
It is possible to consider using the surfacing repair method for anti-corrosion treatment, with nickel-based 625 as the material.
