Corrosion Management & Cathodic Protection

Corrosion Management & Cathodic Protection

OBJECTIVES 

• Reduce the potential for failures by understanding what causes them.
• Understanding the hidden costs of corrosion and its effect on industry.
• Reduce the potential for failures by understanding what causes them.
• Increase productivity by avoiding costly corrosion problems.
• Make sense of measurements and know what they mean.

WHO SHOULD ATTEND?

This course is designed for technical persons working in industries, where corrosion problem is a major concern. Only basic scientific and technical knowledge in the field of corrosion and materials are required. It is suitable for persons new to the field of CP but with some experience in corrosion control, as well as for those who have heavy engineering and scientific background and working knowledge. It is also perfect for supervisors, management, consultants, contractors, engineers, lab trainers and sales/marketing personnel in broad spectrum of industries.
