Oil and gas industries including lower carbon energy - Materials for use in H₂S-containing environments in oil and gas production - Part 1: Materials and materials processing requirements (ISO/DIS 15156-1:2025); German and English version prEN ISO 15156-1:2025
Abstract
This document specifies requirements and gives recommendations for the manufacture and processing of metallic materials for service in equipment used in oil and gas production in H2S-containing environments, where the failure can pose a risk to the functionality of the equipment, to the health and safety of the public and personnel or to the environment. It supplements, but does not replace, the materials specification requirements given in the appropriate design codes, standards, or regulations. This document addresses the metallurgical, manufacturing and quality assurance / control testing requirements, for carbon and low alloy steels, cast irons, corrosion-resistant alloys and other alloys selected in accordance with ISO 15156-2:202x, Annex A or Annex B. Materials selection is not addressed; material selection requirements, including permitted exclusions for specific categories of equipment, specific applications and specific environments are defined in ISO 15156-2. Qualification of materials, manufacturing processes and/or materials specifications that are not listed in this document, are also not addressed (see ISO 15156-3 for qualification and verification of alternative materials, material selection limits, manufacturing processes or materials specifications). Additive manufactured (AM) equipment and components are out of scope of this document.
