Dead-End Dead Leg Corrosion - Corrosion Inspection
- Intentional and unintentional stagnant legs and connections may have a significantly higher corrosion conditions that existing pipe components.
- Piping thickness measurement location (TML)’s and spot T may be misleading as to connection condition
- Digital radiography (DR) and computed radiography (CR) images provide measurable, recordable, remote visual inspection (RVI) accessible, high-quality documentation of condition in non-destructive testing (NDT) form.
- Images can be archived in typical plant data management systems.
