This post was last edited by *aochong_007 on 2018-3-16 at 10:29. Dear teachers: For a fixed-tube-sheet heat exchanger with a diameter of 600, strength calculations show that there is no need to install expansion joints in the shell side. Since anti-scour plates are required for the tube bundle and shell-side openings, an external guide cylinder is considered to be installed, with a diameter of 800. The condition diagram requires that the cylinders of DN600 and DN800 be connected using half of the HZ wave-shaped expansion joints. In this case, can the HZ structure of GB16749 be referenced? Is strength calculation still needed? Thank you!
