Introducing Galvomag™
In 1955 GALVOMAG™ high potential anode alloy was introduced, quickly becoming the standard of quality in the cathodic protection industry. GALVOMAG™ extruded anodes are available in a wide variety of standard and custom shapes and sizes. Specifically for underground applications, Timminco offers several standard sizes of large profile anodes. Each GALVOMAG™ underground anode has a continuous steel core wire running lengthwise through the anode. Anodes arrive at your facility on a standard, palletized package, with one end of each anode counter-bored to expose the core wire. Anodes are ready for lead wire attachment, bagging and backfill.
Performance
The two properties critical to the performance of a sacrificial anode are oxidation potential (directly related to current output) and current capacity (or current efficiency which is directly related to anode life). The typical open circuit potential of GALVOMAG™, using ASTM Standard G97, is 1.70 to 1.75 volts with respect to a saturated calomel electrode. The inherently higher potential of GALVOMAG™ is the reason that GALVOMAG™ anodes have a current output 20 to 30 percent greater than H-l anodes of a similar size. GALVOMAG™ anodes, properly packaged and installed with the appropriate backfill material, also have high current capacities, typically delivering 500 to 550 ampere hours per pound in the ASTM Standard G97 test. High operating performance is one of the reasons GALVOMAG™ anodes are the best buy in reliable, long-term cathodic protection.
Quality
GALVOMAG™ extruded anodes are of the same chemistry, electrochemical properties and high quality that you have come to expect over the years from Timminco. When you invest in GALVOMAG™ anodes, you'll get exactly what you ordered. Our quality assurance process includes both composition analysis and performance testing of production anodes to ensure uniform adherence to high production standards. And our quality process doesn't end with electrochemical properties. We also ensure that GALVOMAG™ extruded anodes are produced to high standards of core wire centering, surface finish, internal soundness, anode weight, and packaging. These things might not seem important on a product destined to spend its life underground but we realize that uniform surface finish, internal soundness and core wire centering translate into a more uniform consumption rate over the life of the anode. And we take extra care to produce anodes that weigh what you expect them to, with a variance typically less than a quarter of a pound from anode to anode.
Quality Assurance
All of Timminco’s products are produced under our Quality Assurance Program, which adheres to stringent process and quality controls throughout all steps of production.
