Magnesium Alloy Sacrificial Anode Price

Magnesium anode specifications are divided into six types by net weight: 2kg, 4kg, 8kg, 11kg, 14kg, and 22kg. All are in the form of trapezoidal cross-sections. The reference length for a 2kg anode is 206mm, for a 4kg anode is 360mm, and for the others, it is 700mm. The steel core used for conduction is made of reinforcing bars with a diameter not less than 6mm. The surface of the steel core should be galvanized, with an exposed length of 100mm. Magnesium alloy sacrificial anode, magnesium anode, magnesium sacrificial anode.

Magnesium alloy sacrificial anode, abbreviated as magnesium anode, is also known as magnesium alloy anode or magnesium sacrificial anode. It is used in cathodic protection systems and is an important equipment and material for preventing electrochemical corrosion. Due to the high potential of magnesium alloy anodes, they are often used for the cathodic protection of buried structures, such as buried oil pipelines, natural gas, and gas transmission pipelines.

Magnesium anode applications: Mainly used for anti-corrosion protection in underground and freshwater environments for oil and gas transmission, water supply and drainage pipelines, underground cables, chemical industry, communications, harbors, ships, reservoir gates, etc. For example, petroleum and gas pipelines, storage tanks, heat exchangers, condensers, etc. Depending on the alloy ratio, magnesium is definitely used. Since it is an alloy, consumption mainly considers the ease of reaction; magnesium is chemically more active than aluminum.

Cathodic protection systems are used to provide anti-corrosion protection for pipelines, storage tanks, etc. Cathodic protection is divided into two types: 1. Sacrificial anode cathodic protection. 2. Impressed current cathodic protection. Magnesium alloy sacrificial anode is one type of anode material in the former. This is a conventional method where a metal more active than the one you are using provides electrons, thereby preventing the metal you are using from providing electrons and undergoing chemical reactions such as rusting or other chemical changes.
This mechanism of using another metal to substitute in the reaction is the anodic protection mechanism in electrochemistry, hence it is called sacrificial anode protection. Magnesium anodes have high driving voltage, low current efficiency, and high cost. Depending on the shape and electrode potential (open-circuit potential), magnesium anodes can be used in soil or freshwater environments with resistivity ranging from 20 ohm·m to 50 ohm·m.

In electrochemical protection methods, there is sacrificial anode protection, where magnesium alloy acts as the anode, causing the magnesium alloy to lose electrons, and the protected metal acts as the cathode (e.g., Fe), preventing electron loss and thus protecting it.
