Significance and Use
3.2 The RC method can be used to evaluate either corrosion inhibitors, or materials, or both. Guide G184 describes the procedure to use rotating cage to evaluate corrosion inhibitors.
3.3 In this test method, 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, and flow. Oil field fluids may often contain sand; however, this test method does not cover erosive effects that occur when sand is present.
