In Part 2 of this interview, welding engineer and futurist Niekie Jooste addresses a wide range of future-facing topics including Education, Resource-based companies/countries, Blockchain, QA/QC, Google, Science fiction and career planning.
Replacement of an existing piping system
Background When process plants have been in service for a long time or approach their end of life the engineering challenges take a different form. It is more complex than laying out a new plant in a greenfield situation. This article discusses some important observations of a project the author had been closely associated with … Read more
Determining SIF of Non-Standard Fitting
Background Some instances in piping stress engineering we come across fittings not defined in ASME B 31.3, due to their sheer size and/or the diameter to thickness (D/t) ratio. Without understanding the stress intensification factors (SIFs) of fittings, flexibility analysis becomes impossible. This discussion is about how a challenge for the determination of SIFs of … Read more
Niekie Jooste – Welder Destiny (Part 1)
In this interview with welding engineer and futurist Niekie Jooste, we get a fascinating glimpse into how work and careers may evolve in the not-too distant future. Niekie shares some of his vast knowledge on welding as it relates to piping engineering, before moving on to artificial intelligence and its potential implications.
To hear more of Niekie’s thoughts on the future and to better prepare yourself for the coming ‘onslaught of the machines’, be sure to check out the Welder Destiny site.
How to restore CAESAR II backups
This video shows you how to restore CAESAR II files using the automated backup feature. Also a couple of tips and tricks to find lost files.
How to show company name in CAESAR II
Introduction When using CAESAR II with network licensing, your company name does not automatically appear in the output reports generated by the program. Instead a message saying ‘Edit company name in <system>\company.txt’ is shown in headers: The same message appears at the foot of the main program window (the initials SPLM stand for Smartplant License … Read more
G’day, I’m a hoop stress engineer!
For much of my career I have been involved in pipe stress analysis in some way, starting with Pipeplus by Algor, moving on to Triflex and then to CAESAR II. After I had a few years of part-time stressing under my belt, I landed a pipe stress role on a three-platform greenfields project in the Timor … Read more
‘Quick and Dirty’ FFS of Fittings
Assessing fitness for service of pipe fittings is tricky. Whilst we’d encourage you to assess them carefully, what about when you just want to know if you should expend the effort to do more detailed analysis or FEA ? Here is a simple approach that can sometimes be employed when you need a first pass … Read more
‘Hot’ sustained stress – method comparison
In the past few years there has been an increased focus on the so-called ‘hot sustained’ stress in piping system analyses. The ASME B31.3 2006 edition clarified that Sustained stress requirements must be met for all operating conditions of a piping system. There had always been practitioners whose view was that any stress due to change in temperature should … Read more
B31.3 Code Issue – Non-conservative Sustained Stress
I would like to highlight an issue in ASME B31.3 that’s been sitting there underneath most of our noses for several years. Depending on your interpretation of the Code (or that of your pipe stress software) this can result in significant under-prediction of sustained and occasional bending and torsional stresses at reducing intersections. [Edit March 2017: this … Read more
