What is the purpose of adding U-bends to the shell of a heat exchanger? Please, experts, help answer this! ! !
It looks like a compensator, but I don’t know what its internal structure is. Just send an internal schematic diagram.
I checked the information; it is indeed a compensator. But this is a heat exchanger with fixed tube sheets, and the length of the tube bundle is fixed. Isn’t there a risk of leakage due to stress on the tube sheets?
This is called a wave expansion joint, not a U-shaped bend: lol
Is it a segmented setting? We also need to take a look at the schematic diagram of the device; it should be included in the device diagram. Judging from that high-neck flange, it should be a medium to high-pressure vessel, and the documentation room needs to be complete. You might as well check and find out.
Calculations have been done, and the expansion joint has undergone stress analysis. It has years of usage experience and will not get damaged.
In fixed-tube-sheet heat exchangers, since the thermal expansion rates of the tube bundle and the shell are different, expansion joints must be used
It should be a temperature compensator, which has a certain amount of deformation space in response to temperature changes
Compensator, also known as expansion joint.
