The non-destructive test system called FRP Corrosion Resistant Barrier Deterioration and Damage Detection that is described can be run while the FRP equipment is in service. The system can alert chemical plant companies to changes in the chemical corrosion barrier which can allow corrective action to be taken before any leaks or releases of chemicals occur. The paper covers the fundamentals, history and development of a concept into a plant-scale working test system. Properly implemented, the system can reduce equipment inspections needed and give substantial reductions in maintenance costs and the need for confined space entries.
