TELPRO Tubular Anodes are manufactured using titanium that meets ASTM B338 Grade 1 or Grade 2 standards and are coated with TELPRO mixed metal oxide coating, which consists of IrO2TA2O5 and is suitable for use in all cathodic protection applications.
Because mixed metal oxide anodes have an extremely low consumption rate, the titanium substrate remains constant throughout the design life of the anode.
Based upon accelerated life testing conducted by an independent laboratory, TELPRO MMO coating has been proven to be equivalent or superior to other mixed metal oxide coatings that are currently being used.
