Buried Piping Engineering

using CaesarII

About the course

Are you engaged in technical matters concerning buried industrial piping? This course imparts essential knowledge of soil mechanics and its influence on underground piping. Upon completion, you will possess a comprehensive understanding of the various technical aspects pertinent to buried piping, catering not only to piping engineers but also offering valuable insights for operators, supervisors, technicians, and plant managers.
Key topics covered encompass relevant design codes (e.g., NEN 3650, ATV, AWWA), solutions to common stress issues, underground pipe support, thrust blocks, awareness of critical aspects, potential failure mechanisms, identification of field and design issues, and distinctions between buried steel and non-steel piping.
The course comprises 7 online modules featuring video content and provides one year of unrestricted access to both the course materials and the discussion forum, enabling you to revisit modules as necessary to reinforce your knowledge for professional projects.
Please note that this course requires an active Caesar II license, which is not provided as part of the course. For inquiries regarding licensing, please don’t hesitate to contact us.
