DIN Blind Flanges (PN 10)
Any piping needs cleaning connections and also additional connections. Blind flanges close these connections during regular operation.
Materials:
- carbon steel
- stainless steel
Lining material:
- PTFE (virgin or conductive)
- PP (up to nominal pipe size DN 300)
Flanges according to EN 1092-1.
Other pressure levels:
- PN 16
- PN 25
- PN 40
Special features:
- earthing stud/lug
Optional extras:
- final painting
