Corrosion & Remaining-Life What-If
Adjust operating conditions to see the live model-predicted corrosion rate and implied remaining life
What-if model: standardized Ridge regression, R² 0.56 on held-out fleet data (3.25 mpy MAE). Runs entirely client-side for instant feedback — see Model Insights for the full fleet-scale ensemble model used for official predictions.
Governing Damage Mechanism — Erosion-Corrosion
API 571 §4.2.13
Mechanical removal of protective scale by high-velocity flow or entrained solids, accelerating the underlying corrosion mechanism.
Recommended inspection approach: UT thickness at flow-direction changes (elbows, reducers); review process velocity against API RP 14E erosional velocity limits.
