Magnesium Alloy Cathodic Protection Performance:
Executive standard. GB/T17731-2015 magnesium alloy sacrificial anode
Magnesium anode is the abbreviation of magnesium alloy sacrificial anode, also known as magnesium alloy anode, magnesium sacrificial anode. According to the electrochemical principle, magnesium alloy sacrificial anode provides cathodic current from magnesium alloy anode material body through soil, water and other electrolytes to the protected body, such as steel structure, so as to make the protected steel structure cathodic polarization and realize cathodic protection. With the continuous flow of current, the anode material is continuously consumed.
Magnesium Alloy Cathodic Protection Advantage
The magnesium anode we provide is an ideal sacrificial anode material with large electric mile per unit mass. It is suitable for cathodic protection of metal structures in soil, fresh water and seawater. Magnesium alloy sacrificial anode is produced according to “National Standard Magnesium Alloy Sacrificial Anode” GB/T17731-2004, and the anode used for pipeline is in line with SY/T0019-97 “Design Code for Cathodic Protection of Sacrificial Anode for Buried Steel Pipeline”.
High potential magnesium anode use production, products in line with ASTM97-98 standard using a specific process, the anode has the electrochemical properties, in the process of cathodic protection, the anode consumption is uniform, so there is a longer service life. In actual use, the actual measured working potential is between -1.8v and -1.85v, thus providing effective protection to the target structure. High potential magnesium anodes are recommended for soils with a resistivity greater than 8000ohm.cm.
Magnesium Alloy Cathodic Protection Application:
Used in cathodic protection system, it is an important equipment and material to prevent electrochemical corrosion. Because of the high potential of magnesium alloy anode, it is often used for cathodic protection of buried structures, such as buried oil pipelines, natural gas, gas pipelines, underground cables, chemical industry, ports, ships and other projects of anticorrosion protection.
