MMO tubular anodes can be directly applied as bare anodes in freshwater or marine environments. When used for cathodic protection of large marine steel structures, they can be combined into remote anodes, which have the advantages of simple installation and wide protection range. In soil environments, MMO tubular anodes are often pre-packaged to form shallow buried anode beds or deep well anode beds.
