Cathodic Protection MMO Anode

Cathodic Protection is a Method Used to Control Corrosion What is cathodic protection meaning for? Generally, Cathodic Protection (CP) is an electrochemical (half electrical and half chemical) method used to control corrosion of buried or submerged metallic structures. Cathodic Protection is a method used to control corrosion. It prevents corrosion by making the protected structure a cathode by installing a more anodic metal (sacrificial or galvanic) anode or a metallic (impressed current) anode connected to a Direct Current (

Detailed Explanation About Impressed Current Anodes for Buried Concrete Structures Galvanic Anodes For buried concrete structures, traditional galvanic anodes based on zinc or magnesium may be used. The required minimum net mass of the anodes is determined from the total current requirement, anode alloy capacity, design life and anode utilization factor. The size and number of anodes is also determined from the anode current output, which in turn is based on anode shape, soil resistivity and anode operating potential. For high-res

How Impressed Current Anodes Are Used for Immersed Concrete Structures? Both Galvanic anodes and Impressed current anodes are applied for immersed concrete structure cathodic protections. However, there are some differences between these two types of anodes. Galvanic Anodes Galvanic anodes for immersed structures will normally be slender stand-off or hull-mounted type anodes and will normally be installed by direct welding of the anode steel core to the embedded steel. This will require breakout of the concrete to expose embedd

How Activated Titanium Anodes Are Used in Concrete Structures for Cathodic Protection? Activated titanium anodes, coated with mixed metal oxides, for use embedded into new concrete structures or applied to existing structures cathodic protection. Applications include anodes within overlays, cast into slots or drilled holes or fixed to the surface under GRP casings. In the appropriate form, these anodes can be embedded in new concrete that is then buried or immersed, as well as the more common applications to atmospherically exposed
