Introduction:
This training course provides a deep knowledge of corrosion and focuses on the examination and identification of metallurgical problems that occur in process units and methods of monitoring and damage reduction.
The equipment costs are a considerable part of the investment in the petrochemical and water industry, and for long-distance, large-diameter pipelines, they can become prohibitively high if the corrosivity of the fluid necessitates the use of corrosion-resistant alloys instead of carbon steel. Better understanding and control of the corrosion of carbon steel can increase its application range and therefore have a large economic impact.
Corrosion Control is an essential requirement in Oil & Gas activities. It utilizes the application of engineering principles and procedures to minimize corrosion to an acceptable level by the most economical method. It is rarely practical or economical to eliminate corrosion completely and in practice, one or more of the following methods would be applied.
Corrosion monitoring provides an early warning that damaging processes or conditions exist which may result in corrosion-induced failures. Moreover, it indicates the correlation of changes in process parameters and their effect on system corrosion. Corrosion Monitoring is essential to evaluate the service life of pipelines and to detect when would be the nearest replacement/shutdown
