ANSI to DIN Flange
ANSI to DIN Flange
(OP)
Hi,
Can we simply change the the Flange type from ANSI to DIN? For example, can we simply convert ANSI #150 flange to DIN PN20? Is there any mathod do convert from ANSI to DIN?
Thanks

Make sure to check the rating of both flanges.
PN ratings of EN flanges generaly dont mate with ASME flanges.

RE: ANSI to DIN Flange
Please correct me if I'm wrong; PN is actually the pressure rating for the DIN / BS flanges which I can directly translated directly from ASME B16.5 table for pressure-temperature rating for example Class 150 flange's highest rating for Group 2-1.1 would be 19.6 bar therefore in DIN / BS would be similar to PN20 and for Group 2.2-1 highest pressure rating would be 15.9 bar therefore in DIN / BS would be similar to PN16. However for higher pressure rating than this would translate to PN100 and PN160 respectively.
I am not very familiar with BS and DIN standard just that recent project calls for requirement of BS and DIN standard.
RE: ANSI to DIN Flange
Be aware that EN 1092 also has material grades and pressure temperature ratings associated so your example might not work.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

The PN20 you refer to is ISO 7005 where they tried to make a blend of both e.g. the series goes 10/16/20/25/40/50/63 etc. and all have metric bolts. The P-T ratings are in the standard but will be similar to the original ASME or Metric flanges from which they come. (The BS / EN standards are BS1560 and BS EN1759 for ASME flanges or BS EN 1092 for the metric flanges.) As inch bolts are still readily available I would just use ASME 150 with inch bolts rather than mess about with ISO PN20 and metric bolts which confuse the fitters on-site who take imperial spanners to what looks like an ASME flange, only to find mm bolts.
