摘要：
During plant startup, similar to 70% of new field-erected aboveground storage tanks showed signs of aggressive corrosion on the bottom underside. Deficiencies in the cathodic protection (CP) system, use of limestone aggregate in the foundation pads, and aggressive soil conditions were found. An intensive tank bottom inspection program was implemented. Several tank bottoms were repaired ou replaced and the CP system was upgraded. No significant signs of subsequent corrosion were found after 10 years.
