Can a heat exchanger use only the tube side?

Can a heat exchanger use only the tube side? Is it okay to use 300-degree nitrogen on the tube side with no medium on the shell side?
Have you considered the pressure difference between the tube side and the shell side? I’ve never seen anyone do this

300°C is a bit high; if it’s at a lower temperature, opening the shell-side vent would work. At this temperature, thermal expansion occurs, so it’s better to use the bypass line
The poster only wants to use nitrogen at 300 degrees in the tube side of the heat exchanger, with no fluid in the shell side. What kind of heat exchange effect is desired? Hehe
What is the purpose of the original poster doing this? If it only serves to transfer fluid, why use a heat exchanger? Just use a pipeline, right?
If the design temperature of the pipe system is above 300 degrees, it should work fine, but isn’t it too wasteful to use it in that way? Why use a heat exchanger when pipes can be used for transportation instead?
Then why go through the heat exchanger? Even with money, one shouldn’t be so willful; otherwise it just becomes a conduit. Over time, excessive temperature differences will still cause damage.
I don’t understand what it means or why it’s done this way
Was a secondary line not considered in the initial design? ~~It is recommended to shut down the machine and add a bypass line~~ I remember there was an incident here where the operator forgot to turn on the valve for the heat exchanger’s circulating water; as a result, the compressor entered its self-protection mode. When the drain valve (on the gas side) was opened, some water had already seeped in~~ Fortunately, it was detected early, so no serious problems occurred~~
Without looking at the design parameters of the heat exchanger, it is impossible to determine whether it can operate in this way.
