Calculation of the floating end plate in floating-head heat exchangers
Thread Content
I remember seeing information regarding the floating end tube sheet of floating-head heat exchangers in a certain book. The calculations outlined in GB151 only take into account the thickness of the tube sheet at the fixed end; theoretically, the thickness of the tube sheet at the floating end should be less than that at the fixed end. Generally, it is chosen to have the same thickness as that of the tube sheet at the fixed end. If anyone has seen this information in a particular book or standard, please send me a picture along with the title of the book – I’d like to find the relevant information there
The fixed-end and floating-end bellows structures are identical in design, with diameters that are similar. The thicknesses are very similar, so it makes sense to use the same thickness for ease of manufacturing. The original poster can use SW6 to calculate and see how much the thickness difference is.
It would be better to have written evidence
It is specified in the book; GB/T 151 Pg57 7.4.1.3 provides an explanation of the calculation model, stating clearly that the two tube sheets have the same thickness.
