Comparison of ANSI and ISO Piping Systems (Pulp and Paper Applications)
Avesta Sandvik Tube AB

<<Stainless steel pipes are widely used in the pulp and paper
industry.The share of stainless steel as piping material has increased at these mills during the last five to ten years.The reasons for this increase have been more corrosion aggressive fluids and environmental aspects as processes have become more closed. In the systems the fluid temperatures tend to rise and concentrations of contaminants (slime and limestone) increase. Also the original quality of raw water may be poor (for example a high chlorine content,etc.) At the most recently built mills all piping are of stainless steel except for steam and condensate pipelines. (316Ti) are steels of this kind.Ti-stabilized grades do not bring any technical advantage compared to grades with a C content below 0.05%.This paper focuses on the ANSI/ASTM 304L and 316L stainless steel grades.>>

<<Chris' Thoughts on Piping Design Automation

Q: I need some URLs for web sites where I can learn piping stress analysis. A few e-books I can download would be OK, too.

1. It's the easiest thing in the world. Just buy FEA software. It'll do everything you want. Look for the words 'user-friendly' on the box so you don't have to worry about bugs or input checking. Just ask the sales person if you're not sure--they're great guys. Don't worry about accuracy, either--that's what they pay programmers for. FEA makes all that mechanics stuff about stress and strain obsolete, so don't clutter up your desk with a lot of books. If the computer makes the number, it's right. Just remember that the red places on stress plots are bummers, everything else is cool. Make sure you get a big fast computer with a lot of megs and stuff and a large monitor. Size counts and chicks dig guys with big monitors. The faster the computer the more stuff you can run and the less reason you have to waste time with an organized approach. (Hint: Big problems make you look good in front of your boss. If you don't complain about running out of memory every month or so, people think you're not making the models complicated enough and they won't respect you.). And always use animation. Any problem worth solving is worth animating.>>
