Readiness check

Is your cathodic protection actually protecting the structure?

Cathodic protection fails quietly. A rectifier can hum along for years while the structure corrodes because nobody proved it met the criterion, the coating was bad, or a survey was never run. Answer for how the system is actually set up and monitored. This is general guidance, not engineering direction; confirm with a corrosion engineer and NACE/AMPP. The score stays on your device; enter an email only if you want the CP readiness checklist sent over.

1. Is the structure well coated, with CP sized to protect the holidays rather than bare steel?Yes, good coating and CP complements itCoating is marginal, CP carries a lotBare or poorly coated, CP is doing it all

2. Is the right system in place (galvanic for small or well-coated, impressed current for large or bare)?Yes, the system matches the structure and current needIt is whatever was installed years agoNot sure what we have or why

3. Do you prove protection against the potential criterion (the -850 mV or 100 mV shift)?Yes, measured to criterion, IR-freeWe read the rectifier but not the structure potentialWe assume it works if powered

4. Do you measure structure-to-soil potential with a reference electrode at test stations?Yes, reference-electrode surveys at test stationsRarely, no regular surveyNo potential measurement at all

5. Do you guard against over-protection (hydrogen, disbondment) rather than just cranking current up?Yes, output set to criterion, not maxedWe turn it up if a reading looks lowHigher current must be better, right?

6. Do you check for stray-current interference on nearby foreign structures?Yes, interference checked and bonds in placeWe have not looked at neighborsNo idea what interference is

7. Are rectifier readings and annual potential surveys logged on schedule?Yes, rectifier checks and annual survey documentedOccasional readings, no real scheduleNo monitoring records

8. Are anodes sized for the design life and replaced before they are consumed?Yes, anode life designed and trackedWe replace when something failsNo idea of anode condition
