Impressed Current Anode


The principle of cathodic protection is to connect an external anode to the material to protect it from corrosion and to pass DC current into it. Thus the whole metal surface becomes cathodic and does not corrode. The external anode may be a galvanic anode (sacrificial anode). It can also be an impressed current anode where the current is impressed from external DC source. Due to its negligible consumption rate, durability and strength, impressed current cathodic protection has longer life than sacrificial anodes. The impressed current anode is also known as dimensionally stable anode (DSA) or insoluble anode. Our impressed current cathodic protections mainly include silicon iron anode, MMO anode, graphite anode and flexible anode.
Corroco International Industrial Co., Ltd is a professional manufacturer and supplier of impressed current anode in China. In addition to this impressed current cathodic protection, we also produce sacrificial anode and cathodic protection accessory. With 12 years' production experience, our products have been exported to the United States, Canada, Britain, Germany, Iran, Pakistan, India, Kuwait, Dubai, Saudi Arabia, the Philippines, Malaysia, Singapore, Congo, Turkey, etc.
