What is it about?

The aim of this open-access article is to show how to implement what we have learned from theoretical hydrogen embrittlement models into the field to provide the industry with valuable data and a practical structural integrity model. A unified and practical industrial model for the prediction of hydrogen embrittlement in steel is presented.

Why is it important?

During planned/forced outages for plant maintenance and repairs, plant operators can carry out laboratory and in-situ tests of undamaged evaporator tubes in critical areas in accordance with the structural integrity model by using the proposed criteria for predicting and preventing future hydrogen-related failures of boiler tubes


The future development of a unified practical industrial model regarding the implementation of necessary measurements of the critical hydrogen concentration that relies on the use of non-destructive sensors, that have been developed for determination of hydrogen content in steels and further quantification of the synergy between the HELP (AIDE) and HEDE mechanisms of hydrogen embrittlement will be the subject of further researches.
