Seek advice on local stress calculation in SW6
Thread Content
Hello everyone, I’m a beginner. I’ve just started learning SW6 and don’t know how to use it. I would like to ask the experts here: the material is S30403, and I need to perform local stress calculations. What should I do next?
That’s right, it’s calculated in this way. For the forces acting in the three directions, you need to consult the piping engineering expertise; all of this has to be determined through piping calculations, it can’t be filled in arbitrarily.

Our small company doesn’t have anyone with expertise in this field either; who can teach me how to calculate these forces? Thank you

Is this how it should be entered? Why are the calculation results incorrect? Where did I make a mistake? Please let me know, thank you!
If stress calculation is required, the selected wall thickness is far from sufficient. (That’s how stress calculation is done.) The opening is large, so only the two calculation methods for the smallest surface can be used. When entering additional data, please convert the units to be consistent. I’ve tried it – thicker version needed, plus a reinforcement ring: lol;P
Have I gone in the wrong direction? The other party showed me the diagram below, but asked me to provide a calculation sheet. I wonder if this diagram is for stress calculation? How was this calculated? Thank you!
If these are the data provided by the other party, then just enter them according to those data; the data must correspond one-to-one with XYZ. If the other party does not provide it, you can refer to the standard for HG or SH, which contains calculation formulas related to DN and PN.
Your unit is wrong; it should be kilograms and millimeters
I tried both methods, but it still indicated that the λ values for both curves were out of range, causing the program to stop running. Guys, if anyone has SW6, please help me take a look and teach me. Thank you!
