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...
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...
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...
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...
Hello all,
I have a trouble assessing the FEA results of a set-in nozzle on a dished end.
Design pressure of a vessel p = 40 atu = 40,53 bar; temperature T = 100°C.
Due to changed pipe routing the existing vessel's nozzle should be checked against the loads from piping, but high stresses due...
Hello,
Since the start of my career as a pipe stress engineer I can't crystalize the matter of whenever does the pipe shoe restricts rotations or not (and which directions).
1) Two major industry companies for which I have worked have guidelines that clearly points out for standard fix points...
