Demystifying Cathodic Protection Course
Introduction:
The integrity of various structures that are buried in the ground, embedded in concrete, or submerged in water is crucial, and cathodic protection plays a vital role in ensuring it. This is especially true in the civil, maritime, and petrochemical sectors. However, the basic principles of cathodic protection are frequently misunderstood, which can give rise to numerous issues. Accidents resulting from inadequate understanding of these principles can have significant implications for health, safety, and the environment.
Course Objectives:
- Understand corrosion mechanisms for various metals, especially carbon steel
- Describe the characteristics of cathodic protection systems (sacrificial anode and impressed current)
- Identify the limits of each technology and their applicability
- Understand basic code requirements (API, CSA and NACE)
- Supervise basic cathodic protection work and maintenance
Who Should Attend?
- Mechanical & Civil Engineers
- Technologists
- Project Managers
Course Outlines:
- Properties of metals & alloys
- Corrosion mechanisms
- Cathodic protection theory
- Sacrificial anodes
- Impressed current
- Design basics
- Applications & causes of failure
- Case studies
