What Do You Need to Know About ICCP Anodes?
An impressed current anode, or ICCP anode, is a specific type of anode utilized in cathodic protection systems to safeguard submerged sheet and tubular pilings from corrosion. Although cathodic protection systems have been in existence for a considerable period, only recently have cost-effective and efficient methods emerged to combat corrosion.
ICCP anodes function through an external current cathodic protection approach, which forces the anodic region. This is accomplished by connecting the power supply’s positive electrode to the insoluble auxiliary anode and the negative electrode to the protected cathode, driving the cathodic area.
Both the ICCP anode and the protected cathode are situated in a consistent electrolyte, ensuring thorough and even contact with the electrolyte. This arrangement allows the surfaces of the protected cathode to obtain free electrons and benefit from the shielding effect of cathodic protection.
How Does an Impressed Current Anode Function?
ICCP cathodic protection serves as an exceptionally effective method for combating corrosion. This technique entails the application of electric current from an external source, typically using an impressed current anode.
Cathodic protection operates through an electrochemical process in which a direct current is impressed onto an ICCP anode, subsequently releasing electrons onto the metal surface to inhibit corrosion. This approach is highly efficient in safeguarding metals from corrosion, regardless of whether they are submerged or buried.
Impressed current cathodic protection systems function by connecting an ICCP anode and a cathode to a direct current (DC) power source. The impressed current anode is directly linked to the metal structure requiring protection, while the cathode is connected to a ground. Upon activating the DC power source, a minor current flows through the anode and cathode, generating a potential difference between them. This potential difference initiates an electrochemical reaction at the impressed current anode, leading to the release of electrons into the metal. These electrons then interact with the metal surface, creating a protective layer that impedes further corrosion.
Difference Between ICCP Anodes and Sacrificial Anodes
When choosing between a sacrificial anode and an ICCP anode for specific protection purposes, it’s crucial to assess each situation individually. Generally, sacrificial anode cathodic protection is more cost-effective and practical for buried pipelines due to low stray current interference, high soil resistivity, and insufficient protection current.

Limitations of Impressed Current Cathodic Protection
While impressed current cathodic protection offers numerous benefits, it also comes with some notable disadvantages that should be considered:
External Power Supply Dependency: ICCP systems require an external power supply to function, which may result in ongoing operational costs and the need for constant monitoring. Additionally, the system’s performance can be affected by power outages or fluctuations in the power source.
System Location Constraints: The impressed current anode system needs to be situated more than 50 meters away from the pipeline to prevent interference with its operation. This distance constraint can pose challenges in densely populated areas or where space is limited, and can also cause interference with adjacent metal structures, particularly those close to the auxiliary anode.
Anode Bed Maintenance Challenges: Sustaining the anode bed in optimal conditions can be difficult because the generated gas might not be discharged quickly enough. This slow discharge can lead to gas resistance, which in turn increases the bed’s resistance and may negatively impact its effectiveness and lifespan.
Stray Current Issues: ICCP anodes can sometimes generate stray currents, which can inadvertently accelerate corrosion on nearby unprotected metal structures. This can lead to unintentional damage to adjacent assets if not properly managed.
Environmental Impact: The installation and operation of ICCP systems may have an environmental impact, particularly in sensitive environments. Careful planning and monitoring are required to minimize any potential negative consequences.
Complexity and Expertise: Designing, installing, and maintaining an impressed current cathodic protection system can be complex and requires specialized knowledge and expertise. This can result in increased costs for training or hiring qualified personnel to manage the system effectively.
Despite these limitations, ICCP anodes remain a valuable and effective solution for corrosion protection in various applications.
