How to determine the weld height, effective thickness of the larger end of the neck, effective thickness of the smaller end, and cut surface height?
Choose g0 based on intensity; choose H based on g0. It is usually the same as g0
That’s how I chose it; you can use that as a reference: weld height, h = thickness of the cylinder. The thickness at the larger end of the neck is the distance from the inner wall of the cylinder to the outer edge of the weld; g1 = cylinder thickness + 2 + 3*(3^0.5), or g1 = cylinder thickness + 7.2. Thickness at the small end of the neck, go = thickness of the cylinder. Shear surface height, h1 = h + 3 (i.e., cylinder thickness + 3)
I saw the previous calculation files; for example, if the cylinder thickness is 10, then 10, 20, 10, 20 is used – is that correct?
For this, input the values according to the equipment flange standards; in the case of non-standard flanges, determine the dimensions based on the requirements outlined in GB150.3 flange design guidelines, and then carry out the calculations. Generally, you can enter the standard value, and by comparing it with the corresponding figure, you’ll know how to fill it in
