* Use limited to DN600. ** –. *** For Type 21 flanges, the outside neck diameter is approximately equal to the outside pipe diameter. Note 1: Dimensions N1, N2 and N3 are measured at the intersection of the neck taper and the rear face of the flange. Note 2: The central face area of a Type 05 flange may be left unmachined, provided its diameter does not exceed the recommended G max. value. Note 3: For dimensions d1, refer to the facing dimensions in EN 1092-1. Note 4: Type 33: lapped pipe end, with no specified thickness or height.

⒜ According to EN 1092-2 (cast iron flanges) and EN 1092-3 (copper alloy flanges), flanges of these DN and PN sizes may be supplied with 4 holes. For steel flanges, supply with 4 holes must be agreed between the manufacturer and purchaser. * Use limited to DN600. ** –. *** For Type 21 flanges, the outside neck diameter is approximately equal to the outside pipe diameter. Note 1: Dimensions N1, N2 and N3 are measured at the intersection of the neck taper and the rear face of the flange. Note 2: The central face area of a Type 05 flange may be left unmachined, provided its diameter does not exceed the recommended G max. value. Note 3: For dimensions d1, refer to the facing dimensions in EN 1092-1. Note 4: Type 33: lapped pipe end, with no specified thickness or height.
TYP 34 · PN 25 Dimensions in mm. DN: nominal diameter. “—” or “-”: no value specified in the document.

Note 1: Dimensions N1, N2 and N3 are measured at the intersection of the neck taper and the rear face of the flange. Note 2: The central face area of a Type 05 flange may be left unmachined, provided its diameter does not exceed the recommended G max. value. Note 3: For dimensions d1, refer to the facing dimensions in EN 1092-1.
