Results from experiments with rotating probes are compared with results from flow loop tests. The methodology is discussed with respect to the determination of parameters and conditions that induce or inhibit flow induced localized corrosion (FILC) in oil and gas field equipment in the presence of H2S. Due to its easy and intens generation of highly corrosive micro-turbulences the rotating probes ('rotating cage') method can be recommended for screening purposes. Materials that withstand localized attack or inhibitors that effectively prevent FILC in this type of test will also perform well under service conditions. However, the rotated cage method may create too aggressive flow conditions. Therefore, loop experiments with their generally lower severity of flow will result in a more realistic qualification of a given FILC prevention method for field use.
