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

 What Factors Affect the Service Life of MMO Anode? Mixed metal oxide (MMO) coated titanium anodes comprise a family of electrodes made from commercially pure titanium to which an electrocatalytic layer is applied by thermal decomposition. The electrocatalytic layers are composed of a mixture of noble and valve metal oxides, the selection of which and their ratio is dictated by the electrolyte conditions in which the anode is immersed. The service life of MMO coated titanium anode range from about 3 years to 70 years. How c
