A tank floor can look perfectly acceptable from above while corrosion is developing where visual inspection can’t reveal it. That’s where tank floor scanning becomes valuable.
Used as part of an aboveground storage tank inspection, floor scanning helps identify areas of metal loss across the tank bottom and gives inspectors information they can use to determine where closer investigation may be required.
What Is Tank Floor Scanning?
Tank floor scanning is a non-destructive testing method used to assess the condition of steel tank bottoms. Technologies such as magnetic flux leakage (MFL) can scan large areas of the floor for indications of metal loss.
Rather than relying solely on what can be seen on the surface, scanning helps inspectors identify potential corrosion affecting the plate, including deterioration that may originate on the underside of the tank floor.
Why Isn’t a Visual Inspection Enough?
Visual inspection remains an important part of assessing tank condition, but not every integrity concern is visible.
Corrosion beneath a floor plate can progress without obvious surface indications. By scanning the floor, inspectors can identify areas that warrant additional examination and use targeted testing to better understand their condition.
This provides operators with a more complete picture of the tank bottom without treating every area as though it presents the same level of concern.
What Happens When the Scanner Finds Something?
Floor scanning is an important screening tool, but an indication isn’t automatically a final diagnosis.
Areas of concern can be marked for additional evaluation using appropriate inspection methods. This helps confirm findings, determine the extent of metal loss, and provide better information for repair and maintenance decisions.
The result is a more focused inspection process and clearer data about where attention may actually be needed.
Better Information for Better Decisions
Understanding tank floor condition helps operators prioritize repairs, plan maintenance, and make informed decisions about continued service.
At Platinum Integrity, tank inspection technology is combined with experienced evaluation and clear reporting to give operators useful information, not simply more data.
