QVF® SUPRA-Line P-Series
Plastic flange ring and insert

Field of Application
- Increased resistance to e.g. HCl/Cl2 containg atmosphere
- Less earthening works in no EX-rated areas
-
Good value solution for DIN-EN connections
Whereas nuts and bolts can be exchanged without taking out the glass component the replacement of a flange ring requires the extraction of a glass component. Hence, in case the glass system is installed in a place where stainless steel corrodes the plastic coupling is the alternative. The P-Series coupling ring is made of glass fibre enforced thermosetting plastic. The pitch hole circle is according to DIN-EN (except DN15) and hence not compatible with QVF SUPRA-coupling ring (except DN15, DN200 and DN300).
If technically possible the plastic rings replace the stainless steel rings in the QVF SUPRA-Line P-Series. Wherever this is not possible the stainless steel surfaces are PU-coated.
The operating conditions of the QVF SUPRA glass items are according to our catalog "The World of QVF". The plastic couplings of the P-Series should only be insulated up to a product temperature of 150°C.
