Print this Course

We currently have no scheduled session for this Mechanical & Process Engineering Training Course. If you are interested in running this course, please contact our Training Department at info@petroknowledge.com


Why Choose this Training Course?

Corrosion is a common and a very expensive problem in most of the industry it is very obvious in chemical, oil and gas industry and in petrochemical, pipelines and storage tanks are most subjected to this problem learning how to reduce it and to eliminate it in few cases can be very useful and highly recommended. 

An understanding of corrosion and its control is vital for any company hoping to avoid the high costs that can be directly or indirectly attributed to corrosion.

There are a variety of techniques which are designed to protect vital components and installations against corrosion. One particular and important corrosion minimisation technique is Cathodic Protection or, Cathodic Protection. This technique can be divided into Sacrificial Anode or Impressed Voltage.

This 5-day training course provides you with fundamental principles, evaluation and applications of Cathodic Protection, helping participants recognise and then select Cathodic Protection control methods.

Particular emphasis will be on the corrosion and Cathodic Protection of port infrastructures, including pipelines, storage tanks and concrete structures.
