Stress analysis of pressure pipelines
Thread Content
Recently, we conducted training on pipeline stress analysis, focusing on pipelines such as those at high temperatures and those connected to sensitive equipment. There are mainly static stress and dynamic stress. Pipeline stress is primarily addressed through material optimization and proper arrangement of supports and hangers. Pipelines are subjected to various loads, such as internal pressure, external pressure, their own weight, external forces, wind loads, seismic loads, thermal expansion and contraction, and pipeline vibrations. Mechanics of materials is the most important; it is basically the theory of mechanics of materials. The software for stress analysis is CAESAR2; I am not very familiar with it yet. I’m a beginner; does anyone have any good advice to share? :)
Mechanics of materials is very important, but it is also necessary to understand some aspects of structural mechanics and elasticity theory. Personally, I think it’s necessary to understand the classification of stresses and the various verification criteria; only then can adjustments be made in a targeted manner. Experience is of utmost importance – by doing more, asking more questions, and thinking more, one will gradually understand it. I’ve only been doing stress analysis for a few months; I understand it a bit now. We can exchange more ideas in the future
I’m a beginner too; I hope we can communicate more
Find some basic books on pipeline stress analysis to read!
I’m also a beginner, but the company doesn’t offer such training opportunities. :Q
Our company uses Ansys for stress analysis
There are many stress analysis software programs available on the forum, including CAESARII, which can be downloaded for free. A quick search yields many results; for example: Introduction to CAESAR, Industrial Pipes | Valves | Accessories Discussion Forum, sor 2008-10-2 8 / 193, 2008-10-31 17:20 by williams; Simulation of nozzles on the top of containers in CAESAR II, Industrial Pipes | Valves | Accessories Discussion Forum, fanking 2008-4-16 17 / 419, 2008-10-30 00:06 by fminwang; Issues related to three-way valves in CAESAR 2, Industrial Pipes | Valves | Accessories Discussion Forum, tangming 2008-10-24 0 / 24, 2008-10-24 22:00 by tangming; Friction coefficient issues in CAESAR, Industrial Pipes | Valves | Accessories Discussion Forum, whn_1982 2008-10-7 3 / 98, 2008-10-24 12:25 by williams; Condition analysis using CAESAR, Industrial Pipes | Valves | Accessories Discussion Forum, whn_1982 2008-9-25 7 / 174, 2008-9-28 10:50 by haohua; Input parameters for CAESARII, Industrial Pipes | Valves | Accessories Discussion Forum, mliu-5 2008-9-17 0 / 112, 2008-9-17 10:26 by mliu-5; Application-related issues with CAESAR 2, Industrial Pipes | Valves | Accessories Discussion Forum, shenyi992 2008-4-9 9 / 719, 2008-9-13 10:01 by dslhac; Input parameters for adjustable orifice plates and start-up gate valves in Caesar II, Industrial Pipes | Valves | Accessories Discussion Forum, tanglu-asap 2008-8-12 0 / 132, 2008-8-12 10:36 by tanglu-asap. ..................

After CAESAR II is installed, in C:\Program Files\COADE\CAESAR II 5.00\C2_Docu, there is: Quick Reference Guide； Applications Guide ； User Guide ； Technical Reference Manual. Take a look at the materials above; with some more practice, you’ll be fine: lol
I also started learning *CAESARII only recently; there are many tutorials available on various forums. But you can watch video tutorials here: http://www.coade.com/support_tutorial.asp
Read more, learn more, do more, ask more
Thank you! This helps us find it. We are working on this project, but we use CAEPipe
I don’t know where to start; there are ready-made examples available that I can use to learn from*
It is very important to have experience with stress management; being able to calculate and make adjustments is what truly counts. Adjustments must be made in a sensible way, and it is only by using stress to create value that one can achieve true success!
Yeah, I’ve started learning this recently as well; I felt quite lost at first, but now I’m getting some clarity after seeing everyone’s advice.
That classmate has the calculation sheets and examples; let’s share them to help with learning*
It’s best if someone can guide you; otherwise, you won’t know whether what you do is reasonable or not after you’ve done it
After installing the CII software, there are examples available; you can also check the help documentation, which should be useful

:funk: :funk: I want to learn too, but I don’t have a teacher or software
