Why Pitting Matters
Pits can act as stress concentrators and may reduce wall thickness locally. On tanks, pipes, marine structures, and structural components, this can affect maintenance priorities and repair decisions.
Visual severity does not always match depth, so measurement may be needed.
Inspection Methods
Assessment may include visual inspection, pit depth measurement, ultrasonic thickness testing, phased array mapping, photographic records, and review of exposure conditions.
The right method depends on asset type, access, surface condition, and the decisions the inspection must support.
Reporting
Reports should identify affected areas, likely corrosion mechanisms, measurement locations, severity, limitations, and whether engineering review or further monitoring is recommended.
