PPDA - FOR BUTT WELDING
Polypropylene encapsulated ductile iron (PP/Steel)
Ductile iron flange with 30% glass fibre reinforced polypropylene encapsulation. A high corrosion resistant flange for use with PE, PP and PVDF stub ends.
Ideal for use in:
- Fish farms aquaculture
- Water
- Mining
- Gas
- Marine
Benefits:
- Unique cross section (like an I-beam), 50% lighter in weight than conventional flange backing rings
- Convoluted shape = bolts do not lose tension, no need for re-torqueing when installed correctly
- Offers huge weight savings
- Available from d20mm up to d1000mm
- Outstanding pressure performance with a safety factor of 2
- Adaptable to both steel and all thermoplastic piping systems
- A much lower embedded carbon footprint

Info
Max. operating pressure: connecting dimensions PN and max. operating pressure in bar are not directly linked. For example: a PPDA Flange in size DA 225- 10 is drilled in acc. to DIN 2501 / EN 1092 PN 10, but max. operating pressure is 16 bar. IPP recommends use of washers (below screw head and nut).
