I’ve have put a excel flange comparison table on the website.

I have not updated the tools page yet, but here it is.

http://pipingdesigners.com/downloads/Fl … arison.xls

It will compares flange diameters, PCD’s, bolts, thickness etc across a range of standards (British Standard – BS10, Australian Standard – AS2129, American National Standards Institute (ANSI), British Standard – BS4504)

Worth downloading.
