The demand for buried piping analysis according to EN 13941 is increasing, but only a few piping analysis engineers are aware of the complexity of this piping code and its design consequences. Standard pipe components like tees and bends are easily overstressed when analysed according to EN13941 and consequently, piping designers and analysis engineers frequently design oversized components.
During this course, participants will be taken through the EN 13941 design standard and learn how the stress analysis for buried piping is performed. Typical trench geometry and soil interaction will be explained, together with the analysis of pre-insulated bonded pipe, standard piping components, PUR-insulation and PE jackets. Workshops are included to reinforce the knowledge built up and to give first hand experience in solving common challenges in achieving code conformance.
To provide a thorough understanding of the principles in the EN 13941 the instructor will present some examples using piping simulation software. In this case the piping software Rohr2 will be used, participants should note though that those with other software packages will be able to follow, as the focus is the EN 13941 and not the buttons that need to be pressed in a given software package.
The course consists of 1 day of online live sessions with the instructors. All training content is provided through your EngineeringTrainer account.
After the course you maintain 1-year unlimited access to the course, including any new course material. This allows you to perform modules again should you need to refresh your knowledge.
