It's fine we're doing elastic with the help of a software and our massive engineering judgement

I agree but for specific geometries like the nozzle/header assembly of my previous post subjected to external loads, i think it will be difficult with just an hand calc

Ok thanks

TGS4 could you elaborate on why Pm is a hand calc only?

Hi, I'm looking for some advice on the new buckling analysis methods of ASME VIII Div 2 edition 2023. I am currently designing a tangential nozzle/header assembly that is subjected to external pressure. Method A is "intended for use on independant component", so my choice was to go for...

Very insightfull TGS4, thank you for the explanation. I'm not familiar with SIF calculation as per Section VIII Div2. In my work for SIFs calculations we only use B31.3 and B31J, which appear to be simplified compared to section VIII Div 2. Stress range calculated with B31.3 is straightforward...

I do not

I did, found no relation between sifs and nde

r6155 care to explain on sifs calculation and nde relation?

Dye penetrant, radio or ultrasound

using UW16 with UG41 probably

non destructive examination?

I don't think sif calculation implies NDE, does it?

In table 1.1, 2.3, if you look at the schema there is a radius r2 for the insert nozzle. Under it there is a direct reference to note 8, which is not the case for the set-in nozzle. That's why i though this note was only for insert nozzle, but i think you're right it is more general than that...

You can have a look at note (8) of B31J. Looks like from the first sentence that insert are better for SIF, since you automatically multiply them by 0.7.

I'm not familiar with designing foundation, but if you consider that the lug are pinned to the ground, then you consider that moments wont be transfered at all to the foundation and will only be sustained by the beams/lugs. In this configuration i don't see why you should design foundation to...

Probably just an overall moment calculated by multiplying reaction force by distance from COG

Kinda curious too on how you designed the weld. The throat thickness should be 9.45mm (0.7*pipe thickness). So how did you get 8mm?

I guess that's the main question politicians need to answer

It depends on the scale of the problem. If the problem is not a big deal, then yes the question is first an economic one, to avoid going to far in the solution. But when the scale of a problem gets big enough, there is a threshold where the economic cost goes second behind actually finding a...
