I still can’t figure out the difference in thickness between the tube sheet and the tube sheet flange
Thread Content
In SW6, the extended section of the fixed tube sheet also serves as a flange input field; there is an item for the \"difference between the thickness of the tube sheet and that of the tube sheet flange\". Could someone please advise on how to enter this value? Thank you.
The SW6 help document states that it refers to the difference between the thickness of the center part of the tube sheet and the thickness of the flange. What thickness does the flange thickness refer to? Some people say it is the center thickness of the tube sheet minus the thickness of the two bosses – is that correct? Is the shell side slot depth also deducted?
Simply put, it is the thickness at the location of the bolt hole.
What was said upstairs is correct; you can refer to the diagrams in the flange standards. The thickness δ specified in those standards refers to the thickness resulting from bolted connections, and the thickness of the tube sheet flange calculated in SW6 denotes this very thickness.
If you think it’s the correct answer, then give it the best answer!
I have taken into account 6mm for the equipment flange in my calculations
The difference between the thickness of the tube sheet and that of the tube sheet flange is the thickness at the center of the tube sheet (which includes 4 mm for the tube side structure and 3 mm for the shell side, i.e., the total thickness) minus the thickness of the flange. This equals 4 mm for the tube side structure, 3 mm for the shell side, plus the thickness of the sealing surface protrusion (6 mm for concave surfaces and 4 mm for convex surfaces), resulting in 13 mm or 11 mm.
I didn’t understand it either at first; later I asked other experienced workers, and they said it’s the difference in thickness between the thickest and thinnest parts of the tube sheet.
