grooved flange DIN 11864-2ANF
grooved flange DIN 11864-2 design A - Aseptic flange connection -
Grooved flange DIN 11864-2
for biotechnology, pharmaceutical or chemical industry
Features
| Type | Description |
|---|---|
| DIN 11864 | aseptic connection without any dead space |
| Pipe dimensions | DIN 11866 Row A + B and DIN 11850 (row 2) |
| Shape A | manufactured with recess for O-ring |
| Sizes | DIN-DN 10-150, ISO-DN 8-100 |
| Material | AISI 316L/ 1.4404, optional 1.4435 (ferrite < 0,5%) |
| Surfaces | inner Ra < 0,8 µm, outer Ra < 1,6 µm (H3) |
DIN 11864 <> DIN 11853
The aseptic and hygiene flange connections acc. to DIN 11864-2 or DIN 11853-2 are compatible
and differ only in terms of the axial length.
Montage
The O-ring is inserted in the groove flange during installation, which automatically holds the O-ring
in place. The collar flange is then placed against it so that both flanges engage each other.
The flanges and the O-ring are therefore coaxially centered. After that, the screws are inserted
through the holes drilled in the flanges so that the heads of the screws are on the outer surface
of one flange and the threads of the screws stick out of the other flange.
The nuts are screwed onto these threads and evenly tightened until the faces of the flanges come
into contact with each other. The O-ring is deformed by this so that a smooth passage free of dead
space and a sealed connection are produced.
Operating pressure
for 140°C and usage of suitable seals
| Tube-OØ | bar |
