AS 21457:2022 adopts and modifies ISO 21457:2010, which identifies the corrosion mechanisms and parameters for evaluation when performing selection of materials for pipelines, piping and equipment related to transport and processing of hydrocarbon production, including utility and injection systems.

This Standard was prepared by the Standards Australia Committee ME-092, Materials, equipment, structures and related services for petroleum, petrochemical and natural gas industries.

The objective of this document is to identify the corrosion mechanisms and parameters for evaluation when performing selection of materials for pipelines, piping and equipment related to transport and processing of hydrocarbon production, including utility and injection systems. This includes all equipment from and including the well head, to and including pipelines for stabilized products.

Guidance is given for the following:

(a) Corrosion evaluations.

(b) Materials selection for specific applications, or systems, or both.

(c) Performance limitations for specific materials.

(d) Corrosion control.

This document is not applicable to downhole components. This document does not provide detailed material requirements or guidelines for manufacturing and testing of equipment.

This document is an adoption with national modifications, and has been reproduced from, ISO 21457:2010, Petroleum, petrochemical and natural gas industries — Materials selection and corrosion control for oil and gas production systems. The modifications are additional requirements and are set out in Appendix ZZ, which has been added at the end of the source text.
