Industrial Corrosion Overview
Uniform loss, localized attack and environmentally assisted damage as integrity mechanisms.
What this topic covers
Uniform loss, localized attack and environmentally assisted damage as integrity mechanisms.
Core ideas
Corrosion changes material through interaction with its environment.
Rate and morphology depend on material, temperature, chemistry, flow, deposits and local conditions.
Corrosion management combines design, materials, process control, monitoring, inspection and maintenance.
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
