Petroleum and natural gas industries - Materials for use in H2S-containing environments in oil and gas production - Part 1: General principles for selection of cracking-resistant materials (ISO 15156-1:2020)

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.
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.
Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions.
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.
This document is not necessarily applicable to equipment used in refining or downstream processes and equipment.

Erdöl und Erdgasindustrie - Werkstoffe für den Einsatz in H2S haltiger Umgebung bei der Öl und Gasgewinnung - Teil 1: Allgemeine Grundlagen für die Auswahl von gegen Rissbildung beständigen Werkstoffen (ISO 15156 1:2020)

Dieses Dokument beschreibt allgemeine Grundlagen, nennt Anforderungen und gibt Empfehlungen für die Auswahl und Qualifizierung von metallischen Werkstoffen für den Einsatz in Einrichtungen der Öl  und Gasgewinnung und in Sauergasaufbereitungsanlagen im Bereich H2S haltiger Umgebungen, deren Versagen ein mögliches Gesundheits  und Sicherheitsrisiko für die Allgemeinheit und das Personal oder für die Umwelt darstellen kann. Es kann angewendet werden zur Vermeidung kostspieliger Beschädigungen infolge von Korrosion der Anlage selbst. Es ergänzt, ersetzt aber nicht die in einschlägigen Konstruktionsrichtlinien, Normen oder Regelwerken enthaltenen Anforderungen an Werkstoffe.
Dieses Dokument behandelt alle Rissbildungsarten, die durch H2S verursacht werden können, einschließlich H2S induzierte Spannungsrisskorrosion (SSC), Spannungsrisskorrosion (SCC), wasserstoffinduzierte Rissbil¬dung (HIC) und Stufenrissbildung (SWC), spannungsorientierte wasserstoffinduzierte Rissbildung (SOHIC), Weichzonenrissbildung (SZC) und galvanisch induzierte wasserstoffinduzierte Rissbildung (GHSC).
Tabelle 1 enthält als nicht erschöpfende Liste eine Übersicht von Ausrüstungen, die in den Anwendungsbereich dieses Dokumentes fallen, einschließlich Ausnahmen.
Dieses Dokument gilt für die Qualifizierung und Auswahl von Werkstoffen für Ausrüstungen, die unter Verwendung von lastgesteuerten Auslegungsverfahren ausgelegt und gebaut wurden. Siehe Abschnitt 5 bezüglich Konstruktionen, bei denen auf Dehnung beruhende Auslegungsverfahren zur Anwendung kommen.
Dieses Dokument ist nicht zwangsläufig auch für die Anwendung auf Ausrüstungen in Raffinerien oder Verfahren und Einrichtungen geeignet, die der Öl  und Gasgewinnung nachgeschaltet sind.

Industries du pétrole et du gaz naturel - Matériaux pour utilisation dans des environnements contenant de l'hydrogène sulfuré (H2S) dans la production de pétrole et de gaz - Partie 1: Principes généraux pour le choix des matériaux résistant à la fissuration (ISO 15156-1:2020)

Le présent document décrit les principes généraux, spécifie des exigences et donne des recommandations concernant le choix et la qualification de matériaux métalliques destinés à être exposés à des environnements contenant de l'H2S, dans les équipements utilisés dans la production de pétrole et de gaz ainsi que dans les installations de traitement du gaz naturel, où la rupture d'un équipement peut présenter un risque pour la santé et la sécurité du public et du personnel ou pour l'environnement. Il peut être appliqué pour aider à prévenir les dommages coûteux occasionnés par la corrosion aux équipements. Il complète, sans toutefois s'y substituer, les exigences concernant les matériaux des codes de construction, normes ou autres réglementations appropriées.
Le présent document traite de tous les mécanismes de fissuration pouvant être induits par l'H2S, à savoir la fissuration sous contrainte par l'H2S et/ou tout autre agent dépassivant, la décohésion interne et la fissuration en gradins, la décohésion interne sous contrainte, la fissuration des zones de plus faible dureté et la fissuration en milieu hydrogénant induite par couplage galvanique.
Le Tableau 1 donne une liste non exhaustive d'équipements relevant du domaine d'application du présent document et comprenant une liste d'équipements pouvant en être exclus.
Le présent document s'applique à la qualification et au choix des matériaux pour les équipements conçus et construits sur la base des méthodes de calcul sous charge contrôlée. Pour les conceptions effectuées sur la base de méthodes de calcul basées sur le niveau de déformation acceptable, voir l'Article 5.
L'application du présent document ne convient pas nécessairement aux processus et équipements de raffinage ou en aval.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore
structures for petroleum, petrochemical and natural gas industries, in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 12, Materials, equipment and
offshore structures for petroleum, petrochemical and natural gas industries, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 15156-1:2015), which has been
technically revised. The main changes compared to the previous edition are as follows:
— new definition on "galvanically induced hydrogen stress cracking" (see 3.14), "chemical activity"
(see 3.27) and "fugacity" (see 3.28);
— inclusion of an expanded description of factors affecting the susceptibility of materials to cracking
caused by H S. The expanded description includes specific guidance provided in ISO 15156-2:2020,
Annex C for gas phase containing systems using H S fugacity (as an alternative to H S partial
2 2
pressure) and application of non-ideal thermodynamic rules for gas-free liquid systems.
