Is it reasonable for the pipe flange to be thinner than the equipment flange?
No one answered, I’ll take care of it myself

I have also encountered this issue; it’s just my personal understanding for reference: whether it’s a tube-side flange or a shell-side flange, the bolt force acting on them is the same, and the design torque required for the flanges is also the same. However, the thickness of the smaller end of the tube-side flange is greater than that of the shell-side flange, so the calculated thickness of the shell-side flange turns out to be greater than that of the tube-side flange.
Let’s pool our ideas and wait for others’ responses
Isn’t this the original file I sent you a few days ago? It can be calculated using your design parameters!
The source file you gave me seems to lack data on the device flanges
You calculated that a thickness of 300 isn’t sufficient; after my adjustments, the thickness is 185 mm, and I also changed the specifications and quantity of bolts. So why are there no details regarding the flanges? ! It might be that there are no flange data for the shell side, but I can adjust the flange of the shell-side vessel to match that of the tube-side vessel, and calculations can still be done!
I spent a long time looking at it and was a bit puzzled. I just changed the water pressure value based on your settings, but the shell-side flange size of 185 indeed isn’t sufficient. Do the parameters of the gaskets also have a significant impact? I see that your required pressure is 50. If we are to use metal wound gaskets, which value should we choose for the pressure?
