标准范围
This part of ISO 15156 describes general principles and gives requirements and recommendationsfor the selection and qualification of metallic materials for service in equipment used in oil andgas production and in natural-gas sweetening plants in H2S-containing environments, where thefailure of such equipment can pose a risk to the health and safety of the public and personnel or tothe environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. Itsupplements, but does not replace, the materials requirements given in the appropriate design codes,standards, or regulations.This part of ISO 15156 addresses all mechanisms of cracking that can be caused by H2S, includingsulfide stress cracking, stress corrosion cracking, hydrogen-induced cracking and stepwise cracking,stress-oriented hydrogen-induced cracking, soft zone cracking, and galvanically induced hydrogenstress cracking.Table 1 provides a non-exhaustive list of equipment to which this part of ISO 15156 is applicable,including permitted exclusions.This part of ISO 15156 applies to the qualification and selection of materials for equipment designed andconstructed using load controlled design methods. For design utilizing strain-based design methods,see Clause 5.This part of ISO 15156 is not necessarily applicable to equipment used in refining or downstreamprocesses and equipment.
