Cathodic Protection

Cathodic Protection

Cathodic Protection is the controlled prevention of corrosion to underground pipes (such as water, sanitary, gas or steam lines), storage tanks (propane or gasoline), and underground metal structures.

Corrosion is an electrochemical process which causes metals to deteriorate in the presence of moisture.

Electric current flows in two ways.

Primarily, it flows within a metal when the electrons of the metal move in response to an electrical pressure or voltage. Metal atoms exchange their electrons readily and these move freely without affecting the atoms themselves. This type of flow does not damage the metal structure.

The other type of current flow causes corrosion. This type is where electric current leaves its metal path and flows into a liquid. Instead of electron movement you have ion movement. Corrosion occurs as these ions break free from the metal surface.

It is estimated that 100 billion dollars is spent each year in the United States for corrosion control. If you have not considered it yet, let us help you determine the best course of action for your project.
