Widely applied materials, used in construction of installations exposed to influence of hydrogen environment, are low-alloy Cr-Mo steels. Unfavorable effect of hydrogen on metals is described as hydrogen stress corrosion or hydrogen embrittlement. The process, in extreme cases, leads to a significant decrease of utilitarian properties of construction materials. In true conditions, a consequence of hydrogen degradation may be a failure, brought about by a los s of construction's integrity. Usage of modem inspection techniques constituting non-destructive testing methods enables monitoring and evaluation of degradation degree of materials, out of which the equipment was built, in a way that does not effect a change of their properties and utili-tarian functions. The presented in the paper research results, obtained under laboratory conditions, are a base for creation of a non-destructive tests methodology that enables performing inspections in true conditions and allows for a better interpretation of results obtained.
