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. calculated checked checked customer checked third-party division amtec amtec name - - date signature (Ver: 7.01) Page 1 print date:
