Calculation problem of heat exchanger flexible tube plate?
Thread Content
Does the regular pressure vessel calculation software have a calculation module for flexible tube sheets?

In fact, it’s good to make one yourself. I once compiled the calculation excel with the straight-edge flexible tube sheet according to the appendix.
Dear poster, can you please upload it so that everyone can learn from it?* study *
Is this heat exchanger tube sheet a flexible tube sheet? How to calculate it?
A similar tube sheet diagram is as follows (the size does not match the drawing, but the style is the same)
You can check sh/t3158 for detailed calculation methods and steps, but the flexible tubesheet structure in the picture is not conducive to stress relief, so the effect should be affected.
There is also a calculation formula in GB/T151, but the design pressure is limited and cannot be higher than 5MPa. sh/t3158 seems to have no pressure limit, but the structural form seems to be different from the tube sheet in the picture I uploaded. After consultation, it was said that this kind of tube sheet can only be designed using stress analysis method. I uploaded the picture of shell process design pressure 7.15MPa
The design pressure of sh/t3158 standard cannot be greater than 6.4MPa, which is theoretically impossible. It seems that we can only use stress analysis and design, and the design fee is 30,000!
