Two shoulders on the tube sheet of the U-tube heat exchanger
Thread Content
When using SW6 to calculate the tube sheet in a U-tube heat exchanger, it is necessary to enter the grooves in the shell side structure and those in the tube side structure. I’m not sure whether the two shoulders on the tube sheet should be considered as structural grooves; if so, would the nominal thickness of the tube sheet equal the calculated thickness plus the thickness of these structural grooves? When designing, what value in millimeters is generally used for these two shoulders? I’ve seen some units use 5 mm – is there any standard specification for this? Thank you!
These two shoulder dimensions are generally set at 4 mm and 6 mm: 4 mm is required for the partition groove, while 6 mm is required for the male and female surfaces of the equipment flange. Of course, these values can be adjusted according to actual conditions (for example, by using non-standard flanges or eliminating the need for a partition groove).

We all perform calculations based on the structural grooving; the values used are those mentioned above. The nominal thickness also takes into account the corrosion allowance and the difference resulting from the structural grooving
