Galvanic Anode
- Magnesium AnodeMagnesium anode is a common sacrificial galvanic anode material used in electrochemical cathodic protection engineering. This galvanic anode is connected to steel structures to prevent or slow down rusting. This magnesium sacrificial anode has high chemical activity, its electrode potential is rather negative, and the driving voltage is quite high. Besides, magnesium anode is difficult to form effective ...
- Aluminum AnodeAluminum anode is used as a part of a technique called cathodic protection (CP). This kind of galvanic anode is also a conductive rod that is attached to metal structures or installed into metal devices. This part is used to reduce corrosion in metal objects including buildings, structures, and home appliances like water heaters. With more than 12 years' research history and ...
- Zinc AnodeZinc anode is a kind of zinc component used to help galvanized steel and other objects. It is often used to prevent corrosion and help other materials corrode more slowly and last longer. The galvanic anode is also a part of a large system which gives objects corrosion resistant abilities. They are common among metallic marine applications, such as boats with metal hulls ...
- Pure Iron Anode Pure iron anode is mostly used for the protection of copper alloys of heat exchanger, fresh water facility, desalination plant (evaporator, brine heater) and condenser. This kind of galvanic anode is also used as a positive pole that has much less carbon than other general irons. This cast iron anode is especially useful in stress corrosion of copper alloys. CORROCO pure iron anode is developed based ...
- External Casing Anode The magnesium anode is characterized by small density, big theory electric capacity, low potential negative polarization rate and large driving voltage for iron and steel (> 0.6 V). Magnesium sacrificial anode is suitable for the protection of metal components in soil and water, where the electrical resistivity is higher. Our magnesium anode is mainly used for anticorrosion of buried pipelines, onshore platforms, huge boilers and steel structures. ...
Description:
A galvanic anode is the main component of a cathodic protection (CP) system, which is used to protect buried or submerged metal structures from corrosion. It is made from a metal alloy with a more "active" voltage (more negative electrochemical potential) than the metal of the structure (typically steel). The galvanic anode (sacrificial anode) is usually attached to the vulnerable metal surface where it is exposed to the corrosive liquid. The potential of the steel surface is polarized more negatively until the surface has a uniform potential. It continues to corrode consuming the anode material until eventually it must be replaced. The loss (or sacrifice) of the anode material gives rise to the alternative name of sacrificial anode. Our galvanic anode mainly includes magnesium anode, aluminum anode, zinc anode, pure iron anode. In essence, it is a kind of galvanic cell reaction.
Application of Galvanic Anode:
The sacrificial anode is widely used in the protection of steel and iron equipments in seawater or river channel. The galvanic anode is also applied to prevent cables, oil pipes, ports, underground equipments and chemical devices from corrosion.
