In the data entry for the SW6 heat exchanger tube sheet, the \"medium properties\" that need to be filled in refer to the properties of the medium in the tube side or the shell side?
Thread Content
The fluid flowing inside the tubes of the heat exchanger is toxic, harmful, and flammable/explosive； The medium in the shell side is a harmless one, and for the SW6 heat exchanger, the \"tube sheet data\" requires the input of medium properties. The question is: for these medium properties, should those of the shell side medium or those of the tube side medium be entered?
What needs to be entered here are the medium properties of the pipe. Since in heat exchanger design, the fluids on the tube side and the shell side are often different, when entering the data for the tube sheet, it is necessary to use the properties of the fluid on the tube side as input parameters. .
According to GB/T151 clause 7.4.2.1, the medium properties are used to determine the minimum thickness of the tube sheet. Figure it out on your own here! :lol
