Hello,
I need to verify external loads from the connected piping on the 1" XS nozzle that is connected to 4" XS pipe via 1" Cl.3000 Sockolet (MSS SP 97).
I am using rohr2fesu, which is a cylindrical shell FE tool for piping elements.
Does anybody have experience and an advice on what approach...
Thanks, I will probably still have to go with these ones as the support concept is already made this way and the project is in the late phase.
The other limitation will be if the Pipe shoe supplier will confirm this loads.
One info - LISEGA provides pipe shoes with trunnion insert for axial...
@LittleInch I did not invent this, this is a concept that was used on the projects before for HP Steam systems under PED III category. So this was also approved by the Notified Body in the past. Other than if you take a look at many spring manufacturers the vertical spring hangers can be...
Hello,
I need to check the shear lugs (axial stoppers) on pipelines with respect to the loads that were calculated in the stress analysis. I came across a project where Finite Element Analysis was used for these components. But is this really necessary? 🤔
What is your approach? Do you rely on...
Thank you all for your responses, and apologies for the delayed reply.
I am conducting a static analysis, not an FE analysis, so I do not need to delve into extensive details.
Thank you for the additional information—it will certainly be useful in other situations.
The confusion arose because...
Thank you for your responses.
Measuring or weighing the component is not an option, sditionally, my question is more general in nature.
For EN standards, the dimensions are clearly defined. In contrast, ASME B16.9 specifies, broadly speaking, that the reducer must be as strong as the...
Hello,
I am seeking advice on the best approach to model pipelines that incorporate ASME B16.11 fittings. These fittings appear to be quite stiff, and my concern is that I might model them as too flexible.
My current approach would be to simplify the model by using the minimum wall thickness...
Hello,
I am performing a pipe stress analysis for a system and have encountered some confusion regarding the wall thickness of reducers.
After reviewing the ASME B16.9 standard, I found that no specific wall thickness is defined for reducers. I also searched through the forum and learned that...
1503-44 Once again thank you for answering, but we are missing the goal of this thread. I already did analysis of the system regarding the locations I have to restrain. I understand what my goals are as a pipe stress engineer. My questions are more related to the execution and feasibility of the...
Hello, thank you all for the advices.
Sorry for not answering, I got sick and had to take some rest. :)
What was the diameter of the pipelines?
KevinNZ - Thank you for the guide tabs advice, I will use them where necessary.
As for the rotating anchor my question was more related to the design...
Hello everyone,
I'm currently working on a piping system of a live steam pipeline (around 500 m long) which serves as a main feed for turbine: DN200, s = 12.5 mm; T = 450°C; p = 68 bar(g).
I am doing a static analysis with ROHR2 software.
I have done numerous analysis for chemical facilities...
Hello,
I have encountered a problem when calculating the allowable stresses for bolts made of A2-70 material.
In a formula 5.2.2-1 of EN 13480-3 it is stated to use the second formula if Rm,t is available...
I wouldn't say it is the wrong tool. The software is designed for this type of problems and it is common to use shell theory for this verifications.
I think it is more the question of an interpretation, knowledge and experience of a 13445-3 standard and of shell theory for this type of...
Thanks for the answer.
Unfortunately, the software is very limited. This is an add-on to the base software which is intended for the pipe stress analysis.
It is mostly used for piping elements - circular, elliptic and oval shapes using shell elements - only shell elements.
