Issues with the connection methods between the tube sheet, the cylinder, and the tube box.
Thread Content
The connection method for fixed-tube-sheet heat exchangers – the calculations in 151 apply to types b and c without flanges, or to type e with flanges on the extended sections. However, in our actual design, we use a connection method similar to type A, but the extended portion of the tube sheet is equipped with flanges. Is such a structure reasonable? If flanges are not used and the heat exchanger is horizontal, the weight of its structure itself may cause deformation. But with flanges, it becomes a problem in terms of calculation. We used SW6 based on type E before; is such a result correct?
Personal opinions can be calculated as type A. The type E is conservative in nature, as the tube sheet does not truly serve as a flange.
