Designing according to the EN13480 code

About the course

The EN13480 design code is frequently used for piping system design for systems in Europe. Often the rules are applied using automated pipe flexibility software packages such as CAESAR II and the engineer can lose the overview of the calculation being performed. This course aims to explain the fundamental equations and principles in these design rules. For example: How is the allowable design stress calculated? Why should certain load cases be analyzed? What inter-stiffener distance is required to prevent collapse under vacuum? How many cycles are permitted for cyclic loads to avoid fatigue failure? This course covers the design rules of the EN13480 code and the similarities and differences compared to the American ASME B31.3 code are discussed throughout.
As well as explaining the rules and how to apply them, you will be challenged on why a rule is formulated in a particular way.
The course consists of 7 online modules based on video content. You receive 1-year unlimited access to the course and the discussions forum. This allows you to perform modules again when you need to refresh knowledge for your work projects.
