Abstract

This document specifies requirements and gives guidance on the verification, qualification and balloting requirements 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 health and safety of the public and personnel or to the environment. The requirements supplement but do not replace the verification (or qualification) requirements given in the appropriate design codes, standards, specifications or regulations. This document establishes a system for the verification, qualification and balloting requirements of materials for equipment designed and constructed using load-controlled design methods. This document addresses cracking mechanisms in production environments 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. This document does not apply to equipment used outside oil and gas production, e.g. in carbon capture, utilisation and storage (CCUS, CCS) or refining or downstream processes and equipment (see ISO 17945 and ANSI-NACE MR0103-ISO 17945), but the guidance and principles can be applied by the equipment user for these applications.
