Study on Servicing Life Assessment Based on Extreme Value Statistics
The maximum local corrosion depth of the air cooler's heat exchanger tube is an important sign to judge servicing life of the air cooler and detecting the maximum corrosion depth of all tube bundles be-comes difficult.IRIS internal rotation rotary ultrasonic testing technology was adopted to randomly select some tube bundles for maximum corrosion depth detection,including applying statistical analysis to the test data and establishing extreme value's statistical model to predict the maximum corrosion depth of the air cooler tube bundle and provide a reference for the residual life evaluation of the air cooler tube bundle.
