Operation And Maintenance Of Pipeline
Cathodic Protection
https://cortec-me.com/
Have you ever wondered how the pipelines are protected from
significant corrosion even after being underground or exposed
for so many years? The answer to that is simple: Cathodic
protection. Cathodic protection is a method for protecting any
sort of metal surface, especially corrosive ones, from almost all
types of corrosion effectively. Without this protection, a metal
surface would start acting like an anode would easily corrode
away. Therefore, for underground pipeline protection, cathodic
protection is the most effective solution. In the following article,
we will go through its operation and maintenance procedures.

Operation
Cathodic protection, as mentioned above, is an
effective measure to prevent corrosion to
underground pipeline systems. However,
cathodic protection could be further divided into
two types based on the operation.

Galvanic Cathodic Protection
This method involves coating the original metal
surface with another more reactive metal. The
latter is called the sacrificial or galvanic anode
and, compared to the original metal, has a lesser
negative electrochemical potential. Therefore,
the galvanic anode is oxidized rather than the
original metal, thus protecting it.

Impressed Current Cathodic Protection
The ICCP is a more effective and economical
method than the other methods when the
equipment, be it offshore or underground pipelines
are much more significant to be protected by
galvanic anodes. In this method, using a rectifier or
an external power source (DC), the cathodic
structure is supplied with electrons.

Maintenance
As useful as this method is, it does require maintenance
every once in a while. It is advised that it is checked every
two to four years for proper functioning. If the design is
faulty, then the areas meant to protect might not receive
enough current, and thus failing the whole protection
method. Therefore, maintenance is essential here. The
maintenance procedure is simple yet requires specialized
types of equipment that should be installed with it for
accessibility. Below stated are four such standard tests for
checking the maintenance of the protection:

• Testing the voltage potential of the pipe-to-soil by
comparing it a half-cell of copper sulfate
• Testing and verifying the pipe continuity
• Testing the anode voltage output
• Testing the current flow between the anodes and
the pipe
