On the calculation of tube sheets in fixed-tube-sheet heat exchangers
Thread Content
While calculating the tube sheet for a fixed-tube-sheet heat exchanger in SW6, I encountered this problem: when choosing the connection method between the heat exchange tubes and the tube sheet, I couldn’t find the option of strength welding plus expansion fitting. What should be chosen in such a case? Additionally, I would like to know how to choose between type a~f tube sheets when designing heat exchangers – are there any guiding principles?
Choosing only “intense welding” might be too conservative.........
So it means choosing welding directly, is my understanding correct?
Generally, it is sufficient to choose strength welding directly; expansion bonding is only an auxiliary measure, and strength welding plays a decisive role in the strength calculation.
Flanging provides little benefit in terms of strength; its main purpose is to eliminate vibration of the tube bundle within the tube sheet. In SW6, welding can be used directly
Okay, now I understand. Thank you for the explanation
