Correlating ANSI Standards to DIN Standards

What subject? All don't have exact equivalents, most are only approximate.

Anyway it is always easier to search on the standard no+din+equivalent.

Dear Sir

First of all, thank you for your prompt feedback.

In Brazil, for steel flanges and fittings, we use ANSI Norm B.16.5, I would like to know if is there any DIN norm correlated with that ANSI one?

Thanks in advance

Now Europe is under the Pressure Equipment Directive(97/23/EC).

one link of dimensions are here for the unified code UNI EN 1092-1

For Flanges You have ISO 7005, DIN 2615, and a few other DINS upto 2638 if I am not wrong for different types of flanges.

prEN13480, part 1 to 5) - piping code
prEN13445, part 1 to 7) - pressure vessel code

Butt welding fittings are DIN 2605, 2609, 2615, 2616 and 2617 (not the same as ASME B16.9, except for main dimensions).
