Politique de choix des matériaux en milieu H₂S

Materials selection policy for H₂S media

Abstract

The representativeness of experimental techniques for determining the resistance of materials to sulfide stress cracking is discussed from the standpoint of the end user, whose responsibility in matters of fitness for purpose is markedly different from that of a supplier or of an independent laboratory. It is shown that the specific service conditions in each application directly define the type of specimen which must be used, together with the experimental procedure, the test medium, and the criterion employed for evaluating the results.
