 Course Overview


corrosion short courses: pipeline external corrosionPipelines play an extremely important role throughout the world as a means of transporting gases and liquids over long distances from their sources to the ultimate consumers. Given the implications of pipeline failures and the role that external corrosion plays in these failures, it is apparent that proper corrosion control can have a major impact on the safety, environmental preservation, and the economics of pipeline operation.  This 5-day course covers various forms of external pipeline corrosion, external corrosion direct assessment methods, and pipeline composite repairs.


This course is available for in-house training, online and distance learning worldwide. It can also be customized to meet the specific needs of your organization.

 In-House Training Corrosion Courses

If you are concerned with corrosion in your business, in-house training is a great solution to train a group of employees from design, production, operation, quality assurance, inspection and maintenance, and technical sales and support on corrosion control and corrosion prevention technology. The contents of all corrosion courses can be customized to fit your organization's needs.


There is no minimum or maximum number of participants required for in-house training corrosion courses. We conduct the in-house training corrosion course at your company's premises and at a time convenient to your company. Requests for in-house training corrosion courses from overseas countries are also welcome.

 Corrosion Course-On-Demand

All our publicly scheduled corrosion short courses are conducted once a year. However, you do not need to wait for one year if you have missed any of the publicly scheduled corrosion courses as we have this unique corrosion course-on-demand scheme: we will conduct the course just for you on an one-on-one basis at a time and in a location convenient to you. This option costs significantly less than a full-scale in-house training program.


Click here to contact us for a quotation for taking this course as course-on-demand.


 Online and Distance Learning Corrosion Courses

All corrosion courses can be conducted through online or distance learning. An username and password will be emailed to course participants for accessing the online course materials. Alternatively, a CD-ROM containing the same online course material or a master hard copy of corrosion course notes can be sent to your organization. Instructions, course assignments, discussions and questions related to the corrosion courses are posted on the website. Free email support for online courses is provided for a period up to 12 months. A Certificate of Completion will be issued to participants who pass the online test with a score of 70% and above.
