Friends, Could anyone tell me where can I find the tolerance for the standard flange? I have been on texasflange webpage and several others where they publish all the numbers for the flange design but there isnt any place where they publish the tolerance on hole size and so forth? I would...

Folks, Has anyone run into problem like this?

Friends, We have run into a REAL huge problem. Our testing is just 1 week away and we found out that flange holes on two casing don't match. We are connecting two casings and flange on each casing has 14+2=16 holes. 14 holes are of 5/8 and 2 holes are 3/4 in diameter. The spacing for the...

metengr, Thanks for your response. You are a great person and greater engineer. Thanks, Shah

M1Can & metenger, Thanks guys for your posts. This is exactly what I was looking for. I just went through Apendix 1 of section II. Are guys are aware of any creep curve for carbon steel in any ASME section? Thanks again for perfect answers. Shah

metengr, Thanks for your candid response. I really appreciate it. I agree with you 100% about all the things you have said. I was going though one of the technical reference by J. R. Foulds And R. Vishwanathan. And they talk exactly what you have said. The thing is, I want to lay out a method...

Brian We have made the several casings for combustor and then later on realized that our worst case temperature was 850 instead 750. So I compared the stresses at 850 allowable so they still meet since we had good safety factor. Also wanted to know, "Does ASME has any section detailing on...

Friends, I really appreciate your response. As you mention that this is not the right material for this application and I dont disgree with that. But the stress calculation at that temperature shows that the stresses are lower than the allowable. And for some reason we can't change the...

Folks, We are running into dilema and need some practical solution. We understand that carbon steel above 800 degree causes graphitization and in long service hours failure may occur. We want to quatify the life and looking for some practical way to assess life at 850F. Any experience...

Barry1961, Thanks for your posting. Could anyone answer the questions regarding the questions about design acceptance criteria?

Dear Experts, I have been struggling with this question since last couple of days. I have bolted joint connection which I want to analyze. I have cantilever type of configuration for my flange connection. And the bolt carries all the dead weight load, pressure load and thermal expansion load...

Jte and SnTMan, I really appreciate your responses. I have mangaed to get ASME Div VIII and now the whole world is crystal clear.

Thanks guys for great response. The material for the cylinder is SA387 Grade 22. It's 2.250 Cr (Jte: Sorry for typo earliar) and 1% Moly. I wasn't very clear on my geometry information. We have 17 inch OD cylinder (A)of 50 inch length and on the ends we have flange welded. I understand from...

I have a cylinder with the flanges welded at the ends. The cyliner will carry 900 degree air with pressure of 115 psi. We want to test this part in the lab and would like to know following. I have used ASME material property for 2.125 Cr & 1% Moly for the calculation. Also the equations are...
