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 15156-1:2015) German version EN ISO 15156-1:2015
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 15156-1:2015); Deutsche Fassung EN ISO 15156-1:2015
Overview
This part of ISO 15156 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 part of ISO 15156 addresses all mechanisms of cracking that can be caused by H2S, including sulfide stress cracking, stress corrosion cracking (SCC), hydrogen-induced cracking (HIC) and stepwise cracking (SWC), stress-oriented hydrogen-induced cracking (SOHIC), soft zone cracking (SZC), and galvanically induced hydrogen stress cracking (GHSC). 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 and constructed using load controlled design methods. For design utilizing strain-based design methods, see Clause 5. This part of ISO 15156 is not necessarily also suitable for application to equipment in refineries or processes and facilities downstream of oil and gas production. Working Committee NA 109-00-01-70 AK "Korrosionsbeständige Werkstoffe" ("Corrosion resistant materials") at DIN Standards Committee Petroleum and Natural Gas Industries (NÖG) is responsible for the German collaboration.
