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 — Amine Corrosion
API 571 §4.2.4
Localized corrosion in amine treating services, accelerated by high velocity, heat-stable salts, and CO2/H2S loading.
Recommended inspection approach: UT thickness at high-turbulence points (elbows, tees, reboiler returns); monitor amine quality (HSAS, degradation products).
