The anodes are composed of titanium ribbon substrate coated with a mixed metal oxide catalyst. The anodes can achieve 50 years life in a current density of 17mA/m. The mixed metal oxide anodes are designed for protecting the bottoms of many large-scale storage tanks. They can be used in sands with various levels of moisture and salt contents without any carbon filling materials.
MMO meshes or ribbons were welded together by metal titanium current distribution member as impressed-current anodes in storage tanks’ bottoms for cathodic protection system.
