Anodes for Cathodic Protection

摘要

Ti Anode Fabricators Pvt. Ltd, Chennai, India has proven technology for making Mixed Metal Oxide (MMO) anodes for a full range of cathodic protection application, by using Impressed Current Cathodic Protection (ICCP) process. The principle of cathodic protection is connecting an external anode to the metal to be protected and the passing of an electrical DC current so that all areas of the metal surface become cathodic and therefore do not corrode. The external anode is to be an impressed current cathodic protection anode, where the current is impressed from an external DC power source. DC current is sent through an insulated wire to the Dimensionally Stable Anodes [MMO coated titanium anodes, Platinised titanium anodes, Platinised niobium anodes or their copper cored with platinum plated surface] buried in the soil near the articles like underground storage tank, pipeline & etc. The current then flows on articles and returns to the rectifier through an insulated wire attached to the articles - Now the article is protected because the current passing on.
