Graphite anodes have been a standard for cathodic protection for many years.They are considered as a reliable impressed current anode and are used extensively throughout the industry. Low in cost, graphite anodes, used in conjunction with carbon anode backfill, provide long-term performance characteristics for many cathodic protection applications.

Available in rod form, CORRTECH machines the anodes for aninternal center connection and then impregnates each anode with paraffin wax to enhance the performance of the graphite and to extend the life of the anode. Factory supplied resin impregnation is also available at an added cost.
