I’ve just started in this field; I only know that temperature difference is a factor to consider. In reality, it’s the axial stress in the shell side, the axial stress in the tube side, and the pulling force on the tube sheet of the heat exchange tubes – these three forces are the actual determining factors. Avoid design oversights caused by small temperature differences, which could lead to quality issues such as damage to the heat exchange tubes in the future.
Original poster, how is the straight-edge length lt calculated according to the latest standards for expansion joints? I also can’t understand the formula for the length of the bellows; I don’t even know where the relevant data can be found. It’s not as simple as with the old standards
