Hydrogen damage in power industry

Hydrogen damage is the generic name given to a large number of metal degradation processes due to interaction with hydrogen. Especially in rower industry, several major components such as steam generator tubes, boilers, steam/water pipe lines, water box of condensers and the other auxiliary components often fail catastrophically due to hydrogen embrittlement. This article consists of a classification of hydrogen damage, brief description of the various processes and their mechanisms, and some guidelines for the control of hydrogen damage in rower plants. Furthermore, same histories of failures of steel components due to hydrogen embrittlement, which are reported in literature, are presented.
