However, under these conditions, a traditional concept of linear corrosion tracking often fails to capture rapid transition to accelerated damage. As wall thickness decreases, the likelihood of failure does not increase steadily. Instead, it can escalate nonlinearly and, in some cases, accelerate exponentially. Small changes in parameters such as Total Acid Number (TAN), temperature, or velocity can shift steels and alloys from a safe operating window into a severe-corrosion regime.</p>
