RGT marine LLC is The Largest Stockists of all type Sacrificial Anodes in UAE and Middle East to provide Cathodic Protection.
One of the most important maintenance tasks when owning a boat is making sure you protect underwater metals, such as prop shafts and the engine, from electrolytic corrosion to prevent wear and damage. This can be done through the use of sacrificial anodes. Boat anodes are fitted or bonded to the desired part and these are easily replaced to offer continual protection. All cathodic protection systems must be inspected annually and the sacrificial anodes renewed if more than 50% are wasted.
Sacrificial Anodes are highly active metals that are used to prevent a less active material surface from corroding. The sacrificial anode will be consumed in place of the metal it is protecting, which is why it is referred to as a “sacrificial” anode.
Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded sacrificial metal to act as the anode. The sacrificial metal then corrodes instead of the protected metal.
As a general guide, for steel and GRP hulled boats, zinc anodes would be most appropriate for salt water applications and magnesium anodes would be more suitable for freshwater applications. However, for boats with a wooden hull, the fitting of magnesium anodes is not recommended as they will have a damaging effect on the timbers around the fixings, known as electrochemical decay. Aluminium anodes are most popular on continental waterway craft.
