U-shaped clamping tube sheet thickness (octagonal gasket)
Thread Content
In GB/T151, the thickness of the U-shaped or type A tube sheet generally refers to the thickness in the middle. The standard states that the thickness of the partition grooves and the thickness of the structural grooves need to be deducted, but has anyone designed a U-shaped tube sheet held by octagonal gaskets? In my personal view, the maximum stress in type A U-tube sheet plates occurs in the middle. Unlike flat gaskets, octagonal gaskets provide radial self-sealing; flat gaskets, on the other hand, offer surface sealing. Therefore, I believe that the grooves in octagonal gaskets do not need to be taken into account when calculating the tube sheet stress. Are there any other opinions?

Thank you, I’ve seen it before. But I’d like to confirm again now, because the shear force in this calculation hasn’t been computed yet. . .
