(OP)
Hi All,
I need to design a custom made flange, which section of ASME I can use or any other method? Thanks for any help

RE: flange design
or ASME VIII Div. 2 Section 4.16
Have a look at Pipemill software at www.pipemill.com
This does the above flange design calcs and similar to Eurpoean codes.

Seems like you have no choice but to make it match whatever you are connecting to: OD, ID, bolt hole dia, bolt circle diameter, material, gasket face dia and type, etc.

Thanks a lot for your info. It was a real help to me. After reading that section I noticed that flange geometry ( D.O, D.I, thickness ) should be just determined by experience and then do calculation to find out whether stress amounts are valid or not. But is there a way to start flange geometry with a good guess, rather than know it by experience?
Thanks a lot in advance,

RE: flange design
We will design everything from now on using only S.I. units ... except for the pipe diameter.

2. Take a similar flange and scale up / down dimensions, then vary and run iterative calcs to find a reasonalbe solution.
3. Always use bolts in multiples of 4, straddling centre-lines
4. Don't forget external loads.

As your last help, your hint was what I was missing. I do believ in your skills
Big thanks.
Cheers,

BighInch ... I like your new slogan. Having dragged ourselves kicking and screaming into the modern era of SI units, pipe diameter has thwarted us again. Now, rather than some inch size OD's matching nb, in SI units, no pipe OD's = nb.
