About the course
6 Live sessions
Starts Oct. 14
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 6 interactive, online live sessions provided by the instructor. Recordings and related training content are provided through our online portal.

This course consists of 6 instructor-led live sessions which consists of presentations, demonstrations and discussions of questions. During each session, participants can ask questions to the instructor (through chat or microphone) which will be answered. After each live session the recording of that session, used slides and exercise documents are made available to participants to view again. If desired by the instructor, exercise files are provided at the end of a session that will be discussed in the next session. These should be performed by the participant before they are discussed in the upcoming live session.
