blind flange, red. thicknessBF.R
blind flange, red. thickness
Blind flange type 05 with reduced thickness
Drilling pattern acc. to EN 1092-1 (old DIN 2527)
Comparison DIN 2527 and EN 1092-1
The European standard EN 1092-1/05 has replaced the national standard DIN 2527 in 2007.
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 - 50 | PN 16 | PN 40 |
| DN 65 | PN 16 (4-holes) | PN 16 (8-holes)* |
| DN 80 - 150 | PN 16 | PN 16 |
| > DN 150 | PN 10 and PN 16 | PN 10 and PN 16 |
* = By agreement, flanges with this PN and DN may also be supplied with 4 holes.
