MMO or Platinised coating is an excellent Electrical conductor and giving well chemical stability, when it will be coated on Titanium or Niobium base, even in very low pH environments.
Major Failure of Cathodic Protection systems are due to the break down of the electrical connection between the cable joints and anodes. These failures will take place, when the anodes connections are jointed by resin based seals.
To prevent such a failures, we developed the hybrid method of "CPCC" cable joints by hot fusion crimping of anode with the copper conductor, covered by polymer cable sheath. After the crimping, the joints are 100% Quality Assured on...

MMO Coating & its Current out put:
MMO coating greatly prolong the life of the anode (low wear rate) and provide excellent chemical corrosion resistance such as acid condition. The standard outputs are as below. However, coating loading may be adjusted to suit a particular current density or design life.
Electrolyte Maximum Current Density
Carbonaceous Backfill - 50 A/m2^
Calcined Petroleum Coke - 100 A/m2^
Fresh Water - 100 A/m2^
Brackish Water - 300 A/m2^
Sea Water - 600 A/m2^
Anode life of all above anodes - 20 years
