Help: How is the difference between the thickness of the tube sheet and that of the tube sheet flange determined? As shown in the figure
Thread Content
How is the value of the difference between the thickness of the tube sheet and that of the tube sheet flange determined? From the drawings, I can see that the flange thickness is 24 mm and the tube sheet thickness is 36 mm. How should this 12-millimeter difference be determined? Is it okay to just perform the calculation with any value entered for SW6? Thank you all
The difference between the thickness of the tube sheet and the tube sheet flange is usually determined by design requirements and engineering standards. The setting of this difference should take into account the structural strength, sealing performance, and manufacturing feasibility. Normally, the thickness difference is calculated to ensure that both the tube sheet and the tube sheet flanges meet the corresponding mechanical and thermal performance requirements under operating conditions. It is recommended to refer to relevant design specifications or consult experienced engineers to determine this thickness difference. It is not recommended to enter values arbitrarily without performing calculation verification. .
You’re welcome. If you have any other questions, feel free to ask at any time! Wish you success in your work! .
It should be 12, which is the difference between the total thickness of the tube sheet and the thickness of the extended portion that also serves as a flange

This value is usually the input (total thickness of the tube sheet minus the thickness of the flange portion of the tube sheet). Assuming that the tube sheet is treated as a blind plate similar to a flange cover, its thickness calculation takes into account not only the thickness of the flange cover itself but also the thickness of the sealing surface, the depth of the partition grooves, and the depth of the stress grooves used for connection with the shell. For example, if a tube sheet is 50 mm thick, with a sealing surface height of 6 mm and a height of 5 mm for the grooves used to separate the sections during processing, then this value is 6 + 5 = 11
