Extreme Value Analysis for Estimating Heat Exchanger Remaining Life

Can we use wall thickness data from a sample of tubes (20 to 30) in a heat exchanger to estimate the minimum wall thickness across all tubes (up to 5000 or more)? Yes! Extreme Value Analysis is a statistical method that can be employed for this estimation. Knowing the minimum wall thickness gives us an idea of the remaining life of a heat exchanger and informs inspection strategies. Check out the presentation below to find out how this is done. As a bonus, you can also access a free online web application that can perform EVA on your data!
