AS 15156.1:2022 PDF
AS 15156.1:2022 adopts and modifies ISO 15156 1:2020, which provides general principles. 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.
The objective of this document is to provide general principles, 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. It can be applied to help to avoid costly corrosion damage to the equipment itself.
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.
This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions.
This document is not applicable to equipment used in refining or downstream processes and equipment.
It supplements, but does not replace, the materials requirements given in the appropriate design codes, standards, or regulations.
