DIN Spec & Certs for ASME fittings/flanges

[Chiller]

I wasn't sure which forum to place this queation, but I guess we vessel guys have more experience/knowledge?!?

Is it possible to buy ASME B16.5 flanges (dimension wise) in DIN material and specification?
Note - I do not mean ASME material flange/fittings with DIN certs.

If they are available, are they:-
1) off the shelf or are they specially made
2) certified per PED 97/23/EC material

Appreciate everyones help.
Thanks in advance

Look for

EN 1759-1
(may be preceded with a DIN, BS or other european)

EN 1759-1. Flanges and their joints. Circular flanges for pipes, valves, fittings and accessories, Class designated. Steel flanges, NPS 1/2 to 24 Current,
Draft for Public Comment £10.00 £20.00

British supplier:

German (DIN) version available at

http://www.beuth.de

I do not have this standard (note that it is still preliminary), but as far as I know this cover flanges with dimensions and ratings compatible to ASME B16.5


Also
ISO 7005-1, Metallic flanges -- Part 1: Steel flanges
This includes flanges of class PN20, PN50 etc. which are compatible to ASME B16.5.

Available at

Note that dimensions (flange thickness but not geometry) and ratings may vary slightly for some sizes. I assume this may be the case also for EN 1759-1

Hope this helps.
