Storage tanks are vital for providing processing plants with the chemicals needed for operations and for storing finished products. However, the corrosive nature of these contents can compromise the tank structure over time, increasing the risk of leaks or, in severe cases, loss of containment. Key areas to monitor include the tank base (where sediment buildup can thin walls due to the concentration of corrosive materials), the roof (where corrosive vapors will pool and can cause vapor corrosion), and any surfaces in direct contact with the stored material. Non-intrusive corrosion monitoring offers an efficient solution for assessing tank health. Permanently installed systems enable continuous monitoring, even in hard-to-reach locations, reducing the need for costly infrastructure associated with manual inspection, while enhancing safety and operational reliability.
