What is ICCP
CORROSION’s ICCP (Impressed Current Cathodic Protection) systems provide protection to a wide variety of vital and valuable equipment, vessels and structures onshore and offshore.
Cathodic protection technology is a type of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, and the protected structure becomes the cathode, thereby causing the electron migration and traction caused by metal corrosion to avoid or cut off the corrosion process. occur.
The principle of cathodic protection is to artificially connect a negative potential to the metal sheath of the cable, and connect a positive electrode to an electrode at a certain distance to ensure that the metal sheath of the cable has a negative potential to the ground. In this way, current will not flow out through the outer sheath of the cable, which will protect the outer sheath of the cable.

working principle
When the metal-electrolyte dissolution corrosion system is subject to cathodic polarization, the potential shifts negatively, the metal anodic oxidation reaction overpotential eta decreases, the reaction rate decreases, and therefore the metal corrosion rate decreases, which is called the cathodic protection effect. The protection method that uses the cathodic protection effect to reduce corrosion of metal equipment is called cathodic protection.
Electrons are introduced into the metal from an external circuit to provide for the reduction reaction of the depolarizing agent, thereby suppressing the metal oxidation reaction (electron loss reaction). When the metal oxidation reaction rate is reduced to zero, only the depolarizing agent cathodic reaction occurs on the metal surface.
Two cathodic protection methods: impressed current cathodic protection and sacrificial anode protection.
Sacrificial anode cathodic protection is to connect a metal with a more negative potential to the protected metal and put it in the same electrolyte, so that the electrons on the metal are transferred to the protected metal, so that the entire protected metal is at the same more negative potential. potential. This method is simple and easy to implement, does not require an external power supply, and rarely causes corrosion interference. It is widely used to protect small (current is generally less than 1 amp) or metal structures in low soil resistivity environments (soil resistivity is less than 100 ohm.m). . For example, urban pipe networks, small storage tanks, etc. According to relevant domestic reports, there are many lessons learned from failures in the use of sacrificial anodes. It is believed that the service life of sacrificial anodes will generally not exceed 3 years, or at most 5 years. The main reason for the failure of sacrificial anode cathodic protection is that a non-conductive hard shell forms on the anode surface, which limits the current output of the anode. The main reason for this problem is that the anode composition does not meet the specification requirements, and the second reason is that the soil resistivity where the anode is located is too high. Therefore, when designing a sacrificial anode cathodic protection system, in addition to strictly controlling the anode composition, it is important to select an anode bed location with low soil resistivity.
Impressed current cathodic protection uses an external DC power supply and an auxiliary anode to add a large amount of electrons to the metal, so that the entire protected metal is in a state of excess electrons, so that all points on the metal surface reach the same negative potential, so that the protected metal structure potential lower than its surroundings. This method is mainly used to protect large metal structures or metal structures in soil with high soil resistivity, such as long-distance buried pipelines, large tank groups, etc.
check test
1. All forced current power supplies should be inspected every two months, longer or shorter intervals may be appropriate. Criteria for normal operation are: current output, normal power consumption, a signal indicating normal operation or a satisfactory level of cathodic protection on the pipeline.
2. As part of a preventive maintenance program, all forced current protective devices should be inspected annually to minimize damage in use. Inspections include electrical faults, safety ground connection points, instrument accuracy, efficiency and loop resistance.
3. Reverse current switches, diodes, interference jumpers and other protective devices, etc., if they fail, may endanger the protection of the structure, their normal function inspection should be performed once every two months.
4. The effectiveness of insulated joints, electrical continuity jumpers and bushing insulation should be regularly inspected and evaluated, which can be accomplished through electrical measurements.
Qualified
When using cathodic protection, the following conditions should be met:
1. The protected structure must be a conductive metal part and have a sufficiently low longitudinal conductivity;
2. There must be no metal conductive connection with low-ohm grounding devices;
3. Both containers and pipelines should have anti-corrosion layers with sufficient resistivity.
Note: As the resistance of the anti-corrosion layer increases, the protection current density decreases accordingly, which is more conducive to uniform current distribution and expanded protection range. When the protection current density increases, the interference effect on external devices also increases.
If pipelines are built or run near high-voltage electrical installations, they must comply with Akf Recommendation No. 3. If, taking into account explosion protection and contact voltage discharge, electrical connections to grounded external equipment are required or such connections must never be eliminated, local cathodic protection technology should be used in accordance with Afk Standard No. 9, recommended.
