Corrosion Control for Gas, Oil, and Water Systems

Introduction:

This course is particularly useful for specialists in the gas, oil, and water industries concerned with corrosion control. It provides extensive information on corrosion theory, practice, and modern prevention technologies. Participants will gain knowledge to reduce maintenance costs, extend equipment lifespan, and ensure asset integrity. The training focuses on metallurgy aspects such as material classification, protective coatings, inhibitors, and cathodic protection. Participants will be prepared for certification as corrosion specialists.

Objectives:

At the end of this anticorrosion course program, attendees will be able to:

• Investigate the materials of construction employed in the oil, gas, and water fields.
• Investigate corrosion theories and mechanisms.
• Identify the major types of corrosion in oil, gas, and water fields.
• Learn about monitoring and inspection techniques for corrosion control systems.
• Apply anti-corrosion measures, such as managing corrosion water, in practice.

Training Methodology:

• Alternative course design
• Onsite practice
• Active investigations
• Project-based tasks
• Interactive experience
• Subject rebuttals & opinions
