For a U-shaped tube heat exchanger with a design pressure of 6.4MPa and a design temperature of -70 degrees, can the sealing requirements be guaranteed if the A-type flange and tube-sheet connection method is used? If not, what method is appropriate?

What kind of flange is Type A flange? It just uses a clamped tube sheet structure. Others don't seem to be able to remove the tube bundle very well.

Type A is a clamping type. This type is suitable for U-tube and floating head heat exchangers. I personally think it should be used.

Type A: The tube plate is connected to the shell flange and the pipe box flange through gaskets. This structure is available.
