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 — High-Temperature Sulfidation
API 571 §4.2.11
Reaction of sulfur compounds with steel at high temperature (>500°F) in the absence of water; rate governed by sulfur content, temperature, alloy content.
Recommended inspection approach: UT thickness per Modified McConomy-curve risk ranking; RT/UT at known high-rate locations identified by process simulation.
