1.1 本规范涵盖了使用旋转笼（RC）评估油田和炼油厂应用的腐蚀抑制剂的普遍接受的程序。 1.2 以SI单位表示的值将被视为标准值。SI单位后括号中给出的值仅供参考，不被视为标准值。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。======意义和用途====== 5.1 油田和炼油厂应用缓蚀剂的选择涉及缓蚀剂在实验室的鉴定（见指南 G170 ).应在实验室中以快速和经济有效的方式模拟现场条件 ( 1 ) . 3 5.2 油田缓蚀剂应在从停滞到典型生产条件下发现的一系列流动条件下提供保护。并非所有抑制剂在该条件范围内都是同等有效的，因此使用一系列流动条件测试抑制剂对于正确评价抑制剂是重要的。 5.3 RC测试系统相对便宜，并且使用简单的扁平样品，允许在每个设置中重复运行。 ( 2- 13 ) . 5.4 在该实践中，提出了一个通用程序，以获得可重复的结果，使用RC来模拟不同类型的试样材料、抑制剂浓度、油、气和盐水组成的影响s、温度、压力和流量。油田流体可能经常含有沙子；然而，这种做法不包括沙子存在时发生的侵蚀效应。

1.1 This practice covers a generally accepted procedure to use the rotating cage (RC) for evaluating corrosion inhibitors for oil field and refinery applications. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Selection of corrosion inhibitor for oil field and refinery applications involves qualification of corrosion inhibitors in the laboratory (see Guide G170 ). Field conditions should be simulated in the laboratory in a fast and cost-effective manner ( 1 ) . 3 5.2 Oil field corrosion inhibitors should provide protection over a range of flow conditions from stagnant to that found during typical production conditions. Not all inhibitors are equally effective over this range of conditions so it is important for a proper evaluation of inhibitors to test the inhibitors using a range of flow conditions. 5.3 The RC test system is relatively inexpensive and uses simple flat specimens that allow replicates to be run with each setup. ( 2- 13 ) . 5.4 In this practice, a general procedure is presented to obtain reproducible results using RC to simulate the effects of different types of coupon materials, inhibitor concentrations, oil, gas and brine compositions, temperature, pressure, and flow. Oil field fluids may often contain sand; however, this practice does not cover erosive effects that occur when sand is present.
