 Hull Anodes

The external protection of hulls is usually provided by means of organic coatings. The protective paint coating, however, is easily damaged in localized areas by mechanical action such as anchors, and by erosion at parts of the stern frame and the leading edge of the rudder. Preferential corrosion also occurs at rivet heads and welds. Cathodic protection can be of value in preventing, or greatly reducing, corrosion at these areas. The cathodic protection of hulls can be achieved with the use of sacrificial anodes.
Hull sacrificial anodes are typically provided in Hydrodynamic shapes in order to reduce water resistance and efficiently protect vessels such as Tankers, Bulk Containers, tugs, etc., that sail on worldwide routes. Anodes are available in a series of welded types with two or four metallic straps protruded from the end of each side, or as bolted types that need to be fixed on permanent studs on doubler plates and under absorpxion rubber pads. Standard types of SYNCOR anodes are kepx in stock for immediate delivery
