How often should the interior of steel tanks with no corrosion protection be inspected?

The optimal frequency for inspecting the interior of steel tanks without corrosion protection is annually. This schedule allows for a thorough examination of the tank's condition, helping to identify any potential issues before they develop into more significant problems. Steel tanks are subject to various environmental conditions that can lead to corrosion and degradation over time. Regular annual inspections enable the assessment of structural integrity and any signs of wear, ensuring that the tank remains safe and functional.

Additionally, inspecting annually strikes a balance between thoroughness and practicality. More frequent inspections, such as quarterly or semi-annually, might not be necessary unless specific conditions or previous issues warrant increased oversight. The annual inspection frequency aligns with industry standards for maintenance, ensuring compliance and safety for users and maintainers of such equipment.
