Fundamentals of Pipe Stress Analysis withIntroduction to CAESAR IITHE WORKSHOP

Piping system design constitutes a major part of the design and engineering eort in any facility. Stress

analysis is a critical component of piping design through which important parameters such as piping

safety, safety of related components and connected equipment and piping deection can be

addressed. The objective of pipe stress analysis is to prevent premature failure of piping and piping

components and ensuring that piping stresses are ept within allowable limits.

 This worshop is designed for personnel from a wide range of abilities and bacgrounds and will cover

the fundamental principles and concepts used in pipe stress analysis. !n 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 e#tensive use of case studies and practical e#ercises

during the course of the discussion ensures as comprehensive coverage of the material as possible.
