Looking for a chart of flange dimensions for the same nominal diameter but different nominal pressures?
Thread Content
I would like to ask everyone: for flanges with the same nominal size but different nominal pressures, what are the dimensional differences? Does anyone have a table of dimensional standards? Could you share one with me? Thank you! ! !

There are also British-style flanges; you need to check the standards for British-style flanges
First, the flange thickness varies; the higher the pressure, the thicker it is； Second, the width of the sealing surfaces differs. Third, when the pressure difference is very large, the structure of the sealing surfaces also changes (such as FF\RF\RJ). . . ）
