Designing according to the EN13445 code

About the course

Cultivate expertise in the EN13445 design code, the essential standard for unfired pressure vessel design compliant with the Pressure Equipment Directive (2014/68/EU). In an era where automated software often obscures the calculation process, this course restores clarity by elucidating the foundational equations and principles that underpin these design rules.
Explore critical questions such as the area replacement rule, the application of the Taylor and Forge method, and the inner-stiffener distance required to prevent vacuum-induced collapse. Gain insights into distinguishing between primary and secondary stresses and their evaluation within the code.
This course extends beyond rote application, challenging participants to understand the rationale behind each rule’s formulation. Moreover, it highlights key distinctions compared to the ASME BPVC Section VIII Division 1 code.
