PN325 standard for flanges

PN325 standard for flanges

PN325 standard for flanges

(OP)
Hi,

An old plant I'm dealing with replacing some piping for uses a PN325 standard for its flanges. This is not covered in DIN EN 1092-1, and from what I can tell from my research (read: googling), the PN325 is a company standard made by the now defunct German IG group, and but is still somewhat commonly used these days in some high pressure process industries. I can't find the PN325 standard anywhere, and the client doesn't have this available either. Does anyone have this standard or know where I can get/buy it (even if it's in German!)? Thanks.

RE: PN325 standard for flanges

I think even if you can find it, will anyone be able to make it?

Perhaps better to simply upgrade to the next standard pressure class up.

Or ask direct to BASF - http://www.technische-services.basf.com/group/corp...

See last page.

Certainly looks to be a non standard flange specific to the urea industry for some reason

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: PN325 standard for flanges

I agree with LittleInch here, as I think I've seen this in a BASF standard for lens ring type joints (WN18-010) as well as in an old Czech standard - ref. number was 13-9732, and the sizes are not the same as the old DIN2696 for lens rings, where PN320 was a little different.
