In modern ICCP-systems, Titanium and Niobium anodes are used. To realise a continuous current electrical conductivity and a long lifetime, the anodes are applied with a thin layer of Platinum or Keramox®.
The composition and thickness of these coatings determine the working and the lifetime of the ICCP-systems.The construction, the electrical output, current density and the characteristics of the electrolyte (freshwater, seawater, etc.) determine the size and shape of the anodes.
Extensive research has, amongst others, led to the development of the KERAMOX® anode. This coating is especially developed to withstand the harsh environment associated with the evolution of chlorine, oxygen and their radicals.The KERAMOX® anode can withstand a high current density (well over 750 A/m2 in seawater) and can have a design life of 10 to 20 years, or even longer. All depends on the customer's requirements and demands.KERAMOX® anodes can be supplied for all types of cathodic protection systems and in any requested size, be it rod, wire, disc, plate, mesh or a combination of these materials.
Frequently seen applications are:
- Internal protection of storage tanks, condensers, pipes, pipelines, heat exchangers and boilers.
- External protection of pipelines, ship hulls, platforms and other offshore constructions, piers, dams and cooling water inlet parts of power stations.
- Tank bottoms.
