NF EN ISO 15156-1

La présente partie résume les principes généraux de choix et de qualification des matériaux résistants à la fissuration en présence d'H2S dans les milieux aqueux dans le domaine de la production de pétrole et de gaz. Le présent document est destiné à aider les utilisateurs à faire un choix judicieux de matériaux pour les composants de forage, de puits, d'installations de traitement et de transport de fluides contenant de l'H2S.

<p>This document describes general principles and gives requirements and recommendations for the selection and qualification of metallic materials for service in equipment used in oil and gas production and in natural-gas sweetening plants in H₂S-containing environments, where the failure of such equipment can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements given in the appropriate design codes, standards, or regulations.</p> <p>This document addresses all mechanisms of cracking that can be caused by H₂S, including sulfide stress cracking, stress corrosion cracking, hydrogen-induced cracking and stepwise cracking, stress-oriented hydrogen-induced cracking, soft zone cracking, and galvanically induced hydrogen stress cracking.</p> <p>Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions.</p> <p>This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see Clause 5.</p> <p>This document is not necessarily applicable to equipment used in refining or downstream processes and equipment.</p>
