ISO 21457:2010 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 includes all equipment from and including the well head, to and including pipelines for stabilized products. ISO 21457:2010 is not applicable to downhole components. Guidance is given for the following:
corrosion evaluations; materials selection for specific applications, or systems, or both; performance limitations for specific materials; corrosion control.
ISO 21457:2010 refers to materials that are generally available, with properties that are known and documented. It also allows other materials to be evaluated and qualified for use. ISO 21457:2010 does not provide detailed material requirements or guidelines for manufacturing and testing of equipment. Such information can be found in particular product and manufacturing standards.
