Cathodic Protection Corrosion Control System from Udemy

Corrosion is one of the most important problems encountered by the owners and operators of underground, offshore, submerged and other metallic structures exposed to an electrolyte. If corrosion is not controlled, it can lead to large costs in repairs or facility replacement. Even greater costs can be incurred from environmental damage, injuries and fatalities.

Corrosion control personnel must have a good basic understanding of corrosion mechanisms. They also need to know the various conditions under which corrosion can occur on underground facilities. In this course, we will focus on the control of metallic corrosion by applying cathodic protection. This course was developed for cathodic protection field technicians, although this knowledge is also needed by corrosion engineering personnel. Cathodic protection (CP) is a corrosion-control technology that involves making a metal surface the cathodic side of an electrochemical cell. Connecting the metal to be protected with a more readily corroded metal to act as the anode of the electrochemical cell is the easiest way to apply CP. In theory, cathodic protection can be used to protect any metallic structure in contact with a bulk electrolyte. However, it is most commonly used to protect steel structures buried in soil or submerged in water in practice. Cathodic protection systems protect a variety of metallic structures in various situations. The most prevalent are water and fuel pipelines, storage tanks, ships and boats, offshore oil platforms, oil well casings, and other applications. This chapter will go through the fundamental principles of cathodic protection and current advancements in the field.
