When designing the tube sheet for a U-tube or floating-head heat exchanger, how is the design pressure of the tube sheet determined?
It depends on how you want to design it: whether it can handle the forces from both sides separately, or through a differential pressure design
Calculated using the software SW6; the results produced by this software already take into account the pressures on both sides of the tube sheet.
A higher design pressure is not the same as a higher bolt load. One is to increase the design pressure, while the other simply uses a common bolt load. The former is more conservative, while the latter meets the requirements of the standards better.
If the flange materials, design pressure, temperature, m,y values, etc., are all the same on both sides, then isn’t the difference between them no longer apparent? If they are not consistent, is there a difference?
I think this is related to the equipment and manufacturing； The process should also take the process requirements into proper consideration.
