Can the thermal displacement of each pipe connection on the heat exchanger be calculated?
Thread Content
The client has requested information on the thermal displacement of each pipe connection in the heat exchanger. Can this be provided?
It can be calculated, but no one does it; usually, it’s the pipeline engineers who consider such things, and it’s useless even if it’s mentioned to the equipment specialists.
I don’t understand what this data is needed for. If an estimation is to be made, the thermal expansion can be calculated by using the wall temperature and the linear expansion coefficient of the cylinder to estimate the displacement; however, this value is usually not significant unless the length is great or the temperature is very high. Moreover, if there are expansion joints in the shell side, the calculation becomes even less accurate. Personally, I don’t think this value is very useful; I haven’t heard of anyone requesting its calculation. It might be useful for very special, individual heat exchangers, but for ordinary heat exchangers, it seems like it’s just an unnecessary requirement: lol
Since foreigners don’t understand this aspect and keep insisting on their own views, this is the situation we have now. . .
This is often requested; it can be calculated simply using the coefficient of linear expansion
