ANSI Flanges >24" 1

[ad90]

Hi,

There seems to be a lack of information available on ANSI flanges over 24" diameter.

Can anyone guid me to where I might find the key info: Overall dimension, number of bolts, size of bolts etc.

Thanks

Andrew

Refer to ASME B16.47, complete with details as requested.

Thanks, I didn't realise there were both Series A & B for sizes over 24".

Very confusing.

I believe there is some information on features/similarities and differences of MANY types, specifications, and some comparative manufacturing features of iron and steel flanges, apparently collated by an API Task Force not long ago at

http://committees.api.org/standards/cre/some/refdocs/docs/07/annex1flanges.doc

Technical book stores also carry the CSA versions in both the imperial and metric versions. They go up to NPS 60 and are fully complete for what you are looking for, blind, RFWN, threaded, weld-on, what have you.
