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 — CO2 (Sweet) Corrosion
API 571 §4.2.2
Carbonic-acid corrosion from dissolved CO2 in aqueous phases; rate peaks around 100–160°F and increases with velocity.
Recommended inspection approach: UT thickness grid focused on low points and water dropout locations; monitor produced-water chemistry.
