I'm looking at a new design for a shell and tube heat exchanger.
Can anyone tell me how the assembly of the tubes into the tube sheets is normally done?
I know we are going to roll the tube ends to attach them to the tube sheet at each end. In this case the tube sheet is welded to the shell on both ends on the finished product.
Is the best way to assemble to insert all the baffles into the shell and thread the tubes through the first tube sheet, baffles, and into the final tube sheet? Or is it better to assemble the whole tube section outside then slip it into the shell and complete the welds on the tube sheets?
Thanks for the help.
