Magnesium anode is casted from high-purity magnesium and installed in a backfill of 75 % gypsum, 20 % Bentonite and 5 % sodium sulfate. This type of anode produces an open circuit potential of 1.65 - 1.70 volts, which is 20 - 30 % greater than conventional magnesium anodes. This high driving voltage means greater protection can be delivered from fewer anodes.

 

Applications of Magnesium Anodes for Cathodic Protection (CP) Magnesium has the highest driving voltage of the materials used for sacrificial anodes and is most commonly used onshore (in higher resistivity electrolytes) where the use of zinc and aluminium would be uneconomical. The most common applications are: Temporary CP Systems The high current output of magnesium in seawater assists in the rapid achievement of polarization potential. This approach has been used where the zinc or aluminium system originally installed has failed to provide sufficient current to achieve polarization. Recent system have included magnesium to provide the initial polarization as part of the system design. Temporary protection of land and other pipelines during construction and before the energizing of the impressed current system. The anodes are easily installed within pipe trench as construction proceeds; additional excavation is not required. De‐scaling of tanks. The high potential and consequent hydrogen evolution at the cathode leads to rapid removal or surface scale. External protection of ships; hulls whilst is fresh or brackish water. This often consists of anodes suspended over the vessels’ sides. Permanent CP Systems Land pipelines. Magnesium anodes have a particular effective role in urban areas or where there are other buried services in the immediate vicinity. Service pipes to domestic and commercial premises. For small diameter and short length pipes, the current required is very low and the anode mass is usually between 0.3 and 1.0kg. Two types of anode are in common use. The first type consists of an insert that screws directly into a "blind tee" that is fitted into the service pipe. This is cheap and easy to install but does not allow the performance to be monitored. The second type consists of a small cast or extruded anode that is packaged in the same way as the larger anode types. Connecting the cable via a test point allows for monitoring. · Short pipelines including river crossings. · External surfaces of buried storage tanks, particularly oil tanks in hazardous areas. · External surfaces of caissons in fresh or brackish waters. The higher resistivity of these electrolytes prevents a cost effective protection system using zinc or aluminium anodes. · Internal surfaces of water storage tanks and treatment plants. The deposits are non toxic and magnesium anodes may be used in potable water systems. · Internal surfaces of calorifiers, heat exchangers and condensers. · Protection of "hot spots" on otherwise unprotected pipelines. "Hot Spots" are areas where soil conditions are highly aggressive. · Supplementary protection on pipelines with impressed current CP systems in poorly protected areas, often due to coating
