How to conduct corrosion monitoring during the long-term operation of petrochemical plants
Thread Content
Typical petrochemical plants undergo maintenance every 3 or 4 years. During such maintenance periods, how does the petrochemical plant in question carry out corrosion monitoring? Is this approach effective? Additionally, how do developed countries handle this task? Those who have expertise in corrosion monitoring are requested to share their information.
Corrosion monitoring methods include: the most commonly used ones are fixed-point thickness measurement, chemical analysis, corrosion coupons, and online corrosion probes; other methods include hydrogen flux, FSM, infrared spectroscopy, etc
