It is not a problem. START-PROF has a free viewer. Anyone can download it and check the model and analysis results

No problem,
You can evaluate the trial version here
This is my pipe stress anlaysis training course
and see videos on youtube

I can suggest this video
Forces from hydraulic analysis software should be transferred into pipe stress analysis software and applied at all bends and tees. At each moment of time you have the specific distribution of the forces in all bends and tees. The forces can be in same direction or in...
This is explained in my complete pipe stress training course

Short description. Nozzle can be modeled:
as an anchor, without flexibility
as flexible restraint, with local nozzle to shell connection flexibiity
as flexible restraint, with local and global vessel...

EN 13941 and ISO 14692 codes has equivalent stress that include ring bending stress from the soil. But ASME B31.4 and B31.8 not.
Also you write "I am dealing with is a restrained slurry pipeline, as it will be buried". If the pipeline is buried, it doesn't mean that it is restrained.
It could be...
ASME B31.3 and B31.1 don't have any methods for pipe stress analysis of PP piping. And CAESAR don't have this feature
In this course I explain how to analyze it using DVS 2210 and 2205 codes

There is no HDPE in CAESAR
In this training course I explain how to analyze HDPE, PP, PVC

Just add expansion cushions. Usually it reduce stresses a lot. See paragraph 4.1 here https://www.passuite.com/kbase/doc/start/WebHelp_en/index.htm#t=gruntmodel.htm
If not help, then add U-shape expansion loop
I think thrust blocks is not good idea. Expensive and unnecessary.
I'm the...
It is described here: https://blog.passuite.com/minimum-design-metal-temperature-mdmt-and-impact-test/
And actually it is usually done automatically. No need in manual calculations

ax1e,
Yes, but the main question is how to determine the V and P values and how to apply it to model the unbalanced force effect correctly. After that we can decide how to place the supports to avoid the problems.
This is a very interesting question for me. Did anyone tried to model this...
MJCronin,
Thank you for your answer. I am the author of one of the articles you mentioned. Unfortunately, my question is a more complex. I want to find the real engineering practice for determining of temperatures Ttop and Tbottom. Maybe there's some recommended practice, articles, books that...
This is a very interesting question. Some of our users ask me for it, but I'm not sure what to answer. ASME B31.1 Appendix II has no clear recommendations about it.
My opinion is that when PSV opens, the unbalanced pressure forces should be applied step-by-step in the direction of the flow. It...
Simple description:
API 617
NEMA SM 23
API 617 and NEMA SM 23
In general, API 617 is just 1.85 times NEMA SM 23 allowable.
NEMA SM 23 is 1.85 times more conservative
How to calculate the temperatures on the top and the bottom of the pipe for LNG?
How to decide which slope of the pipe is critical, when we should not consider the thermal bowing effect?
Is there any literature about this?
RVAmeche, how to delete the existing node in CII?
What is modeled piping logically? What if I modeled it not logically? I can't change anything?
All bad numbers are painted by red color. Your goal is to eliminate all red color. But to understand how to do it, of course you need to have basic...
