This course is designed for personnel from a wide range of abilities and backgrounds and will cover the fundamental principles and concepts used in pipe stress analysis. In addition to meeting the needs of design, the course is structured to provide you an in-depth understanding of the engineering principles involved in material selection, application of code criteria and the capabilities and tools incorporated in stress analysis software. The extensive use of case studies and practical exercises during the course of the discussion ensures as comprehensive coverage of the material as possible. The course will introduce CAESAR II software.

At the end of this seminar participants will:

• How stress analysis is carried out in piping systems
• The fundamental aspects related to selection of piping materials
• The objective and scope of piping codes
• The theory behind piping system stresses and failure theories
• The basis for determining the design pressure and temperature conditions
• The methods employed to determine pipe wall thickness
• Piping system loads and their characteristics along with code criterion for designing piping systems
• The design criteria for thermal stresses in piping systems
• The significance of pipe stress analysis software in general, with particular emphasis on CAESAR II and the tools and procedures used in the creation of stress models
