Corrosion Monitoring
How thickness data, coupons, probes, chemistry and inspection evidence can be combined conceptually.
What this topic covers
How thickness data, coupons, probes, chemistry and inspection evidence can be combined conceptually.
Core ideas
No single corrosion-monitoring method describes every location or damage mechanism.
Trends are more useful when measurement points and operating conditions are comparable.
Monitoring data should be linked to process changes, leaks, repairs and inspection findings.
Program tradeoffs
Localized damage can make simple averages misleading, so engineering decisions need representative evidence and applicable acceptance criteria.
What good evidence looks like
Repairs, pressure testing, entry and live process work are specialized activities outside this site's procedural scope.
Lifecycle perspective
Trend tools here illustrate data behaviour only and never establish safe remaining life or retirement limits.
