An improved mechanism for evaluation of degradation criticality is described. Corresponding apparatuses, systems, methods, and computer readable media are provided. The evaluation of corrosion criticality is utilized to estimate a failure pressure of a pipeline that is subject to structural degradation (e.g., metal loss corrosion). The evaluation, in some embodiments, is utilized with a specific tool configured for controlling or otherwise regulate pipeline operations responsive to the estimated failure pressure. The evaluation is a specific technical process whereby multiple failure paths through anomalies (structural defects arising from degradation features) are utilized in concert to determine an estimated failure pressure. The failure pressure, in some embodiments, is used to control actuation of one or more valve regulator features or to guide excavation.
