The calculation problem for a cooler
Thread Content
There is a cooler: the design pressure for the shell side is 0.4, the temperature is 40, and the fluid used is water； The design pressure for this pipe train is 1.0, the temperature is 150, and the medium is air. The structure is as follows: both the left and right tube boxes are secured using flanges; the cylinder has a diameter of DN350. All flanges are custom-made, of type SW6. Which calculation module should be used for this? I previously considered calculating it as a floating head, but I felt that the calculation was incorrect; therefore, I am seeking advice from forum members on how to calculate a cooler with this type of structure Thank you!

Obviously, this cooler is a stuffing box type heat exchanger sealed with O-rings.
Figure 2 does not represent a stuffing box; it appears to have a loose-flange structure, with the flange on the tube side shell being movable and adjustable
The poster’s diagram should include cross-hatching and weld lines to facilitate understanding
In Figure 2, it’s not very clear, but the tube sheet should also be fixed; otherwise, the tube sheet and the shell flange won’t be able to seal properly. So both ends have fixed tube sheets, and it should be calculated based on fixed tube sheets
