ISO 21457:2010确定了在为与碳氢化合物生产的运输和加工相关的管道、管道和设备（包括公用设施和注入系统）进行材料选择时进行评估的腐蚀机制和参数。这包括从井口（包括井口）到稳定产品管道（包括稳定产品管道）的所有设备。ISO 21457:2010不适用于井下部件。 提供了以下指导: 腐蚀评估； 特定应用或系统或两者的材料选择； 特定材料的性能限制； 腐蚀控制。 ISO 21457:2010是指通常可获得的、具有已知和记录的特性的材料。它还允许对其他材料进行评估并获得使用资格。ISO 21457:2010没有提供设备制造和测试的详细材料要求或指南。这种信息可以在特定的产品和制造标准中找到。

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.
