What Do You Need to Know before an ICCP system Installation? Impressed current cathodic protection is applied by coupling the metal to be protected to the negative pole of a direct current source , while the positive pole is coupled to an auxiliary anode. Impressed current anodes should be inspected for compliance with specifications for anode material, size, and length of lead wire and to confirm that the anode cap (if specified) is secure. Lead wires should be carefully inspected to detect possible insulation defects.

What Reference Electrodes are Mostly Used in Cathodic Protection System? Reference electrodes are used to measure the polarization potential of cathodic protected structures. They shall be kept in contact with the same electrolyte (soil or water) surrounding the structures, and the voltage that rises between the structure and the lead cable of the electrode, measured with a high-impedance voltmeter, gives an indication of the effectiveness of Cathodic Protection. Depending on the electrolyte where the reference electrode will be u

What is an Impressed Current Cathodic Protection System Consist Of? Impressed current cathodic protection systems are capable of operating at significantly higher current density, it can work in any resistivity electrolyte such as soil,  freshwater seawater, etc. Once installed, it only requires annual system checks. Instead, galvanic systems require frequent replacement. Generally, an impressed current cathodic protection system consists of DC power, MMO anode, reference electrode, junction box, and so on.   Direct Cu

What You Need to Know about Cathodic Protection? Cathodic protection is a method used for controlling or mitigating the corrosion of a metallic structure by turning the structure into a cathode. This can be accomplished either passively or actively; passively by connecting the metal structure to another metal that corrodes rather than the structure (galvanic anodes), or actively by applying direct current to an anode connected to a structure (impressed current). Both methods cause the structure to become cathodic and mitigate corro
