Pipe stress analysis

Summary

Understand the methods underlying pipe stress analysis and learn how to solve any design issues.

Pipe stress analysis (PSA) is a key part of a safe design of pressurised systems, driving decision on piping specification, layout, supports arrangement, requirements for flexible joints, flange design and others.

Although piping engineering has been known for its highly complex models and monograms to establish safe layouts and configurations, the development of computers now enables analysis to be performed more accurately and quickly of time than ever before. 

In order to get the full benefit of the use of pipe stress analysis software, users must first have a good understanding of piping systems, the components, mechanical behaviour, engineering models and piping code rules underlying the computer analysis.

This course provides the necessary background to comply to the piping codes, carry out the stress analysis and problem solve; including the requirements for pipe stress analysis and an efficient process workflow. 

Delivered with worked examples using CAESARII software, which is the defacto industry standard in many sectors for Pipe Stress Analysis, this course teaches methods and techniques that are applicable to not only to CAESARII but to any pipe stress analysis software that engineers use. 

As well as teaching how to use the software, the course discusses the place of PSA in the design lifecycle, best practice for analysis and ways of streamlining the design. 

Exercises cover the setup of the model, definition of geometry, branches, SIFS, boundary conditions, support and load definitions, looking at various types of supports, idealisations and assumptions, and discussing modelling of various fittings and inline items.

Further exercises look at the analysis of the results and optimisation of the layout: adding flexibility, reducing code stress reducing nozzle loads and restraining deflection.

The course finishes with an overview of the results presentation and reporting.
