Many Thanks.
It is interesting that any overlap is permitted. You would think that the standard would not recognize class 900 flanges of size 2" and below so as to avoid confusion. Within this class and size range, the standard could simply indicate use of components of the next higher class...
Thank-you both.
I have seen flanges stamped with PN10 and others with PN16, and I am told that flanges stamped with PN10/PN16 exist. It is just interesting that such an overlap would be permitted. I would have thought that PN10 flanges would not be recognized/allowed where physically...
EN 1092-1 PN10 and PN16 slip-on plate type flanges have identical dimensions up to and including size DN150. However, even though fabricated of the same material, their pressure/temperature ratings are different. For example, if fabricated from Material Group 3E0 (P245GH), PN10 flanges are...
