Has anyone ever seen a shell-and-tube heat exchanger with more than a certain number of shell-side sections?

As the title says! If there are more than two stages in the shell side, what are the challenges in the equipment manufacturing process?
Generally, two shell passes are sufficient; more than that is really unnecessary. The overlapping configuration can be used to increase the number of shell passes; 3 overlaps have been seen.
Thank you for participating! I agree with you. I just chose a setup with three units connected in series, but the user wants them to function as one unit; this requires many division points in the shell side, which seems unreasonable! ! !
I have worked on several double-pass designs, but the actual heat exchange capacity does not reach the designed value; this is likely related to the heat conduction through the partitions. It is recommended to use an overlapping design instead
Let’s learn together* to gain knowledge; thank you all
