Hi Can anybody give me the proberties of ASTM A193 Gr. B7? Especially, I need the modulus of elasticy. Thank you very much Claude

Another question. Whats the meaning of the theta values: slope of flange face at outside/inside diameter, resp.: change in slope which flange pair undergoes due to an unbalanced moment (Y-3). I can't picture myself the meaning of it. Claude

Ok, sorry, found H_C was a bit blind, but the question if the exist sample calculations is still on hand :-) Thanks Claude

Hi I have to use Appendix Y for a calculation. I was wandering if there exist sample calculations to ease the forst contact with the Appendix. I was wondering for example how to calculate H_C exactly. Thank you very much. Claude

Yes it's a ASME flange. So the calculation isn't really necessary, am I right? But I want to include the calculation into my calculation report anyway, since the other flanges are all NON-ASME flanges and need verification. For all other flanges I have O-ring Gaskets. I don't have a...

The gasket is asbestos free! Thanks

BPVC Sect.8 Div.1 I have a flat ringtype gasket (class 300 NPS 3) made of synthetic fiber + nitrile binder. For the flange calculation I need too choose a material from Table 2-5.1 (p.355 ASME BPVC Sect.8 Div.1) to get the factors m an y. Which of the listed should i choose? Thanks Claude

I have another question. Using the formula (3.F.2) in div 2 annex 3.F, is it allowed to determine the stress amplitude by finite element calculation? Thanks

The situation is the following. The valve I'm calculating has been designed after european code. Now the model is going to be installed in canada, and has to be checked by the asme code. So the design is already put, and hopefully doesn't have to be changed. Thanks for the help, if I have...

Thanks for the two replies. The material is A350 LF2 I was looking pretty much everywhere, I'm just starting out with the ASME code.

Hi I have to perform a fatigue analysis for a valve without any welds. There used to be fatigue curves, giving max. allowable stress by the number of cycles. This curve isn't present in the 2007 version anymore, or at least I couldn't find it. Does anybody know where to look now in Division 2...

Hi I'm looking for the mechanical properties of A 350 LF2. And what is important where are this properties written in the ASME Code, for reference? Thanks for the help.CLaude
