Chemical plants operate across a spectrum from continuous petrochemical processes to batch specialty operations, each presenting distinct integrity challenges. Process Safety Management requirements add a governance layer that demands rigorous change control — every metallurgy substitution, process condition change, or operating envelope modification must be captured, assessed, and approved before execution.
Reliatic ships with a pre-loaded damage mechanism library for Chemical & Specialty. Each mechanism is linked to its relevant inspection techniques, examination intervals, and regulatory acceptance criteria.
Transgranular cracking in austenitic stainless steels exposed to chloride-containing environments above 60°C, often initiating at crevices and under deposits.
External corrosion of carbon and low-alloy steel beneath insulation, particularly problematic in chemical plants with frequent wash-down and outdoor piping.
Dissolution of the protective oxide layer on carbon steel in single-phase and two-phase flow systems, creating localized wall thinning at elbows and tees.
Combined mechanical and electrochemical material removal in slurry lines, catalyst transfer systems, and high-velocity process streams carrying suspended solids.
Alkaline stress corrosion cracking in carbon steel equipment handling amine solutions for acid gas removal, concentrated at welds not post-weld heat treated.
Outcome
Maintain PSM compliance with governed MOC workflows while optimizing inspection scope across batch and continuous operations with different degradation profiles.
