This course will discuss common classes of material used in the Oil and Gas industry in relation to the service environment and design criteria. The various corrosion mechanisms and corrosion damages encountered in the Oil and Gas industry will all be considered during the course. Influence of process parameters, fluid type, CO2, H2S and O2 corrosion process and factor influencing them will be discussed. Through analysis of the chemical and physical characteristics of the system the precipitant will estimate the system corrosivity with the recap and review of materials selection and coatings for corrosion resistance for different conditions and applications. Fundamental to Cathodic protection (CP) will be also discussed. CP survey techniques for buried structure as well as factors to be considered when designing of a Cathodic Protection system (e.g. estimating current requirements) will be explored. The participant will learn how to select and utilize corrosion inhibitors for different systems based on the fluid type and service environment. Selection of the appropriate corrosion inspection and monitoring techniques will also be discussed. Furthermore, Risk Based Inspection as a current trend in defining the inspection frequency requirements will be explained.
