• 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
