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...

Denying a full study in one sentence is a bold moove. No i'm not saying that

I know nothing about plants, i'll assume your right. So climate change casualties will be mitigated by this fact? If so it is a good thing to know This is even worse, as this "attempt" isn't even intentionnal . So the consequences are completly unknowned. It is indeed better for current...

Like when they starts dying during summer My point exactly. And mass release of CO2 by humans is probably the biggest attemp we've ever done. Indeed because the consequence is not just global warming, but climate change in general. Experts cannot predict the future so it is indeed not an...

Not talking about mass extinction, just mass calsualties

Wasn't trying to make a point really, i was just refering to your argument. History told us that adaptation to radical shifts in animals means mass casualties and even extinction of many numbers of species who couldn't adapt. . Ecologists have written countless reports trying to predict what...

If by coping and enjoying this change you mean waiting for mass casualties in undevelopped countries and maybe the developped ones until equilibrium is reached, then this is certainly true

I think the difference here is in the Army Core of Engineers. There is no Army of Core of Engineers who studied the mass released of Co2 in the air. We're just discovering that it causes an important variation on the equilibrium of plants, and kinda praying that it doesn't have any big effect...

Isn't it a bad thing that there is such a perturbartion of a natural phenomenon? There is complex equilibium in nature, small variation of one variable can lead to disaster.

There is a good youtube chanel of an experienced guy that does pressure vessels inspections. He explains in some videos how he takes notes of corrosion and stuff. Search "Mr Eric"

@jt1234 It is not the first time i see you putting ego in your answer. Please don't think to much about questions and answer them to your best, as it is always valuable ressources for us new engineers.

@r6155 I understand thanks for the answer. @XL83NL good remarks, also i should say that our temperature designs start at +65°C so the delta is closer to 300°C. Maybe we should be careful when using repads, i'll try to see if there is any recommandation in the code

Could you elaborate? We use reinforcing pads at low temperature around -200°C

Hello In the B31.3J, general note 7(e) says : The flexibility and stress intensification factors apply only if the following conditions are satisfied: (e) - the matching run pipe thickness, T, and diameter, D, are maintained for at least two run pipe diameters on each side of the branch...

Nevermind! It gave the same results i forgot to switch from sus to expe when doing the final case... Sorry for useless post

But it's not though. I've tried it on my current model, and i've got completly different stresses

Hello, Flexibility analysis : I have an operating case OPE1 = T1 + W + P1 and another one OPE2 = T2 + W + P1. I get two expansion cases : EXP1 = OPE1 - SUS and EXP2 = OPE2 - SUS I then can get a final expansion case to get the full range case between T1 and T2 : EXP3 = EXP1 - EXP2. What is...

Yes aha les accents weren't the problem. However i found a solution that works partially, i can delete in the include piping files all the path that i'm not interested in and just keep the relative path. It then stays with the relative path

True but B31.3 requires flexibility analysis with stress intensification factor to calculate stresses at junction. You have to consider a whole lot of load cases, so it can be pretty time consuming. In that the simple but limited opening reinforcement calculation of div VIII section 1 can be...
