Example anodes

Independent evaluation of the performance of anodes used in cathodic protection systems is conducted by Southwest Research Institute (SwRI). Evaluations are performed under controlled soil resistivity and cathodic protection conditions.


Currently, there are no clear guidelines about how to select anodes; therefore, independent testing is of interest. In addition, the useable lifetime of the anodes is not well known because consumption rate data is typically available from vendors. Tests conducted were designed to measure consumption rates and provide a side-by-side comparison of relative performance of multiple anodes.
