Environmental Effects on Equipment and Piping – Level I: Corrosion Damage Mechanisms (Nuclear & Thermal Power Plants and Petrochemical)

Designers must consider environmental degradation factors to eliminate, reduce, mitigate, or delay adverse environmental effects on equipment and piping components to an appropriate level by applying experience, research, and conservative design principles in the design and appropriate selection of materials and manufacturing practices. This course includes the following degradation mechanisms:

• Stress Corrosion Cracking;
• General Corrosion;
• Pitting Corrosion;
• Crevice Corrosion and Denting; and
• MIC and Fouling.

The following subject matters will be discussed for the above-mentioned mechanisms:

•  Description of degradation mechanisms;
•  The materials susceptible to the degradation mechanisms;
• The preventive measures, design measures, material control, and critical parameters to avoid component degradation; and
• The mitigating actions and remedies such as material changes, stress  mitigation, stress control, and appropriate coatings.
