If the client specifically writes that he want a pressure sealed bonnet, then your bolted bonnet will probably not be accepted.
But the easiest way to find this out is of course to ask him directly.
The only EN socket weld standard I know about is EN 12760 (Socket welding ends for steel valves), but EN 1759-1 fully describes the dimensions of the socket so for the flange you would only have to specify EN 1759-1 type 14.
Yes they are fully compatible if created with the same SE version.
ST4 will probably not be that much more demanding on the hardware than ST3, but that's me guessing.
2GB of RAM isn't that much these days when you take all the other programs that are running on your computer together with SE...
Since the code doesn't give you a safety factor for 250000h, then I don't think you have any other choice than to use the factor for 200000h which is 1.25
It's austenitic and precipitation hardened, so it's strength at room temp is more in line with what you would find in a ferritic or martensitic fastener, but it performs much better then them at high temperature.
It also got great oxidation and corrosion resistance.
I don't know if all that...
F91 was added to B16.34 in an addenda 1998, my guess is that you are looking in the original 1996 edition if you are coming to the conclusion that it's not covered by the standard.
The only limiting factor for the test pressure is that the membrane stress in the part shall not go above 95% of the yield stress (90% in ASME) during testing.
Yes you recalculate your Cv based upon the test pressure you will be using (60 psig) and multiply that with 0.01%.
It's only if you had a valve with leakage class V that the pressure class would start to matter since that test uses the maximum operating differential pressure across the valve as...
Kelly, can you elaborate on your statement about 1,34xPN?
The 1,43PN is taken directly from the PED and that pressure will create a stress in the material that can be up to 95% of the yield strength of the material, which also happens to be what most EN standards specify as their max allowed...
Well a flanged valve is tested according to EN 12266-1 with the following pressure:
"The test pressure (see A.1.6) shall be a minimum of 1,5 times the allowable pressure at room temperature."
You are right, 1092-1 doesn't mention anything about hydrotesting.
In ASME B16.5 regular flanges doesn't need hydrotesting, but flanged fittings do and I think it works the same way in the EN world.
That was a really frustrating part, impossible to do anything with it even with ST3. Pretty amazing that such a simple part can be so problematic.
I deleted your swept protrusion and restored the sketches and did a new swept protrusion in ST3 and this is what I could do then...
I've only skimmed through the Self-paced training, since it's pretty massive: 28 Courses for ST3, 13 for ST2 and 11 for ST.
The course "Modeling a Part Using Surfaces" is over 300 pages long so massive might even be an understatement.
The Siemens self-paced training can be found here...
You can change the diameter by just clicking on one of the cylinders in you "U", click the cylinder and you will see a callout with the value of the diameter, click the callout and edit the value.
You should also check out live sections, this was a great improvement of the synchronous work flow...
I would also say that one of SEs biggest strength right now is that it has its "big change" a few years behind it (synchronous tech + ribbon gui).
Pro/E just recently died and got reborn as Creo
Autodesk Inventors fusion technology is still in beta.
Solid Works big change (going all cloudy +...
