remarks:

To model the flange with tube plate as practical as possible, the depth of the recesses has been reduced so that the seals are in the main power circuit. To model the grip length and the thermal expansion of the tube plate correctly, the height of the tube sheet has been taken into account by expansion sleeves. Reducing the clamping length of the changes in the recesses is balanced with the sleeve length.
