Below is a list of Graphite Anodes manufacturers from Greenville, Michigan. Graphite anodes are used to conduct electrical current into polarized electrical devices, also know as cathodic protection anodes. Cathodic protection is the process of using a more easily corroded metal as the anode of an electrochemical cell with another metal surface. It is commonly implemented in applications such as underwater or underground pipelines and storage tanks, steel piers, equipment on ships and boats, offshore platforms and reinforcement bars in large concrete structures such as tall buildings.
