Course Overview:
The course explains corrosion in great detail including dry corrosion, aqueous corrosion, ideal material selection, and techniques for corrosion prevention.
It also describes material deterioration such as erosion, atmospheric corrosion, and stress corrosion cracking as well as include some articles on failures of pipelines, tanks, pressure vessels and heat exchangers.
Such participants will learn modern techniques and means of corrosion monitoring such as coupon testing for corrosion and ultrasonic thickness measurement.
The course is beneficial to people like engineers and those who select materials and maintenance personnel and gives them crucial understanding needed for corrosion prevention and mitigation in industrial machinery. The course ends by a final quiz and feedbacks session.
Course Objectives:
Upon the successful completion of this course the participants will:
- Determine if internal corrosion exists by evaluating a set of criteria to identify and apply monitoring techniques such as:
- Understand the fundamental theories of aqueous corrosion and dry corrosion
- To understand basic metallurgy and choice of material selection suitable for the specific application
- To enable the attendees to grasp the advanced information in preventive as well as predictive maintenance of equipment
