TELPRO Rod Anodes are manufactured using titanium that meets ASTM B348 Grade 1 or 2 standards and has been 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 which are currently being used.
Strict quality control procedures are followed throughout the entire coating process to guarantee proper coating, adhesion and loading. Also, TELPRO products are tested using an X-ray fluorescence spectrometer to ensure production of the highest quality product, which is fundamental in every step of the manufacturing process.
TELPRO Rod Anodes are available in diameters of 1/8” (3.175mm), 1/4” (6.35mm), 1/2” (12.7mm), and 3/4”(19mm), as well as many other sizes which are all available
