The issue of the thinnest shell thickness
Thread Content
Everyone, how do you determine the thinnest shell thickness when designing heat exchangers? For example: 1. When the pressure is low but the diameter of the shell is large, conventional calculations suggest a thickness of 10 mm for a shell diameter of 3000; however, intuition suggests that this thickness is too small. Although GB151 specifies a minimum thickness for the shell, it is unclear whether this thickness is reasonable and where it comes from 2. For containers supported by lugs, the lug standards specify requirements regarding the minimum thickness of the shell. If these standards are not met, how should one calculate whether the shell is still safe? Thank you.
The minimum thickness of the heat exchanger is determined primarily by considerations of rigidity; for example, during maintenance, the heat exchange tubes need to be removed, and if the thickness is too low, the tubes are prone to deformation.
Thanks for the reply from above. Does that mean as long as it meets the standard requirements, it’s okay?
