GD2,
thank you for the hint regarding class 1 and class 2 vessels. In fact, there was no specific information if the vessel should be class 1 or class 2. I assume it is class 2, because the customer wishes an FEA and only some of the design rules in VIII Div2 part 4 to be checked (cylinder...
Thank you all for your replies!
The initial task was to design the vessel acc. to VIII-2 part 5 using a finite-element-model (design by analysis). In addition, the design rules in VIII-2 part 4 governing internal pressure should be checked. This is how I came across the fact that the vessel...
Thank you for your reply!
The alternate rules in VIII-1 App. 1-4(3) for the considered torispherical head leads to 15mm wall thickness, which is much more than VIII-2 would yield. The straight cylinder acc. to VIII-1 has the same wall thickness as acc. to VIII-2 (9.9mm).
If approximately...
Pre-calculatoin of torispherical heads acc. to ASME BPVC VIII Div.2 2023 (4.3.6.1) leads to a thinner wall than a simple cylindrical shell (4.3.3.1).
Also, the minimum wall thickness of the same torispherical head acc. to ASME BPVC VIII Div.1 2023 is much thicker, whereas for a straight...
