Calculation of the Remaining Life of Corroded Tan

Abstract

Because it is difficulty to collect field corrosion data,estimation of the remaining life of corroded tanks mostly adopts qualitative analysis. On the basis of the relationship curve of the corrosion depth and service time,according to the acquisition of corrosion data sample size,the paper used limited polyline to replace the corrosion curve,simplified the calculation of the remaining life of corroded tanks.
