Two Different Cathodic Protection System Cathodic protection is a method to reduce corrosion by minimizing the difference in potential between anode and cathode. This is achieved by applying a current to the structure to be protected (such as a pipeline) from some outside source. When enough current is applied, the whole structure will be at one potential; thus, anode and cathode sites will not exist. Cathodic protection is commonly used on many types of structures, such as pipelines, underground storage tanks, locks, and ship hull

MMO Anodes for Impressed Current Cathodic Protection (ICCP) Systems Impressed current cathodic protection systems (ICCP) are used to provide cathodic protection for pipelines, ship hulls, offshore production platforms, water, and wastewater treatment equipment, tank farm, and of course underground storage tanks. It requires an external DC power source that is energized by a standard AC current.    ICCP Anodes Type are Consist of:   Mixed Metal Oxide Anode: Mixed metal oxide anodes consist of electroca

How MMO Tubular Anodes Connect to Cables   The cable to mmo tubular anode connection is critical to all impressed current anodes. Lead wire connections at the end of the anode often resulted in a higher rate of consumption, or “necking”, at that end of the anode that resulted in premature loss of lead wire connection. To help prevent the necking of the anode at the connection point, select anodes that were manufactured with an enlarged end if solid rods are to be specified. In addition, specific external epoxy enca

Carbon Backfill of MMO Anode in Impressed Current Cathodic Protection For nearly all underground installations, a special carbon backfill, referred to in the industry as coke breeze, is provided in the anode hole or well. This special backfill can lower anode ground bed resistance, and resulting in lower rectifier design voltages and reduced probability of stray current interference. It also improves current distribution along the anode since the backfill will provide a generally uniform environment to avoid premature anode fail
