plate flange, red. thicknessGF.R
plate flange, red. thickness
Plate flange type 01 with reduced thickness
Drilling pattern acc. to EN 1092-1 (old DIN 2576)
Comparison DIN 2576 and EN 1092-1
The European standard EN 1092-1/01 has replaced the national standard DIN 2576 in 2007.
New in EN 1092-1 are the pressure levels PN 16 and PN 40 for plate flanges.
For dimensions up to DN 40, the EN refers to the standard series of PN 40 pressure level.
From DN 50 to DN 150, the EN refers to the standard series of PN 16 pressure level.
For nominal sizes larger than DN 150, EN standardizes pressure levels PN 10 and PN 16.
| DN | DIN 2576 | EN 1091-1 |
|---|---|---|
| DN 10 - 40 | PN 10 | PN 40 |
| DN 65 | PN 10 (4-holes) | PN 16 (8-holes)* |
| DN 80 - 150 | PN 10 | PN 16 |
| > DN 150 | PN 10 | PN 10 |
* = By agreement, flanges with this PN and DN may also be supplied with 4 holes.
