Marine Anodes
SACRIFICIAL ANODE CATHODIC PROTECTION SYSTEM( ALUMINIUM & ZINC )
FOR SHIP'S HULL & TANK
Sea going Vessels ( Ships) are prone to corrosion. Good Quality Paint system augmented by effective Cathodic protection system ( Sacrificial Anodes ) completely takes care of the hull and other areas of the ship from corrosion.
Effective cathodic protection of ship hulls and similar marine structures in seawater against corrosion has been widely
emonstrated for many years using either zinc or aluminium alloy sacrificial anodes. Magnesium alloy is applicable for fresh water conditions.
Cathodic Protection is normally applied to the whole underwater hull which includes the typically cavitation – corrosion prone areas around the stern and in particular inside kort nozzles and bow thrusters where extremely high water velocities are experienced. Anodes are also fitted in recesses such as seawater inlet boxes where shielding from exterior hull protection may occur.
Sacrificial Cathodic Protection is also applied to ship's cargo and ballast tanks –either Aluminium or Zinc depending on the compatibility of the Anode material with the application /service of the Tank( Ballast /Oil-Petroleum cargo etc)
The quality of the anode and especially the alloying procedure is of outmost importance for the performance of aluminium nodes which are generally more Susceptible to pasivation than zinc. However aluminium alloys have an electrochemical capacity which is more than 3 times greater than the capacity of zinc and it is nowadays the most widely used alloy for the cathodic protection of ships and other marine metallic structures.
SVM anodes are manufactured from primary metals of high purity, homogenized in suitably Designed melting furnaces and have pre-casting quality control ( Chemical composition is checked by Spectrometer ) in order to secure that the concentration of all important elements (either impurities or alloying elements) even in very low concentrations is strictly conforming with the
specification.
Sacrificial Anodes performance –Electro chemical properties –Capacity; Open circuit Potential are also tested regularly as per DNV standards .
We can always manufacture Anodes as per customer specific requirements
