Unique Flange PE100

Unique Flange PE100

patented, for PN 10, PN 16 and PN 25 piping systems

 

 

 



  • The PE Unique Flange is designed as a fixed flange and is fitted with a loose flange. This allows the valve to be selected one dimension smaller than with a conventional loose flange connection which reduces the risk of deposit-build-up thereby cutting project costs.
  • for direct and misalignment-free connection of PE pipes to metal valves without loss of cross section and without reduction of nominal diameters
  • this enables the connection of plastic pipes to metal valves with the same nominal size and pressure class
  • identical cross section improves the flow properties, reduces dead space and the risk of deposits, enables also pigging and the use of butterfly valves without being obstructed by the flange adaptor
  • PE 100 Unique Flanges are with integrated loose epoxy-coated ductile iron flange DIN EN 1092-1 PN 10 and PN 16, PN 25 available upon request  
  • with extended fusion spigot for electrofusion DVGW approved Register No. DVGW PE part 

     - DV-8606 BT0423, OD 75 mm to OD 225 mm
     - DV-8611 BT0424, OD 250 mm to OD 630 mm

  • optional flanges: stainless steel, galvanised, with flat sealing surface and without flute and O-ring, slotted holes, PN 25 
  • a integrated O-ring provides maximum safety, the O-ring already seals at low tightening torques. Standard tightening avalues increase safety (see DVS 2210-1 Sheet 3 Table 5). Optionally with a flat profile gasket.
  • externally de-beaded on request
  • cost saving as a valve can be selected one nominal diameter smaller than otherwise

Trouble-free connection to valves

Our Unique flange allow the connection of PE pipes to steel or cast iron valves without changing the nominal diameter. This considerably reduces the total cost. 

 

A connection without offset

  • improves the flow characteristics
  • reduces deposit buildup
  • allows pigging 
  • permits use of butterfly valves

 

 

For a dead space or misalignment reduced connection to a valve,
please inquire using "to valve connection".

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Optimal flange to valve connection

 

The ideal combination can be found in the adjacent table. 

In some cases a HP Flange as well as a Unique Flange can be installed. 

For connections above OD 355 mm we recommend using our Unique Flange instead of a traditional flange connection.

instead of a traditional flange connection.

When using a bolt circle with the same PE pipe dimension, the Unique Flange reduces the standard bolt circle by one DN

Minimize project costs

Noticeably higher savings are possible with very large pipe diameters 

Cost reduction due to the reduced DN stage, the project costs are reduced considerably. For example a DN 300 Unique Flange can be used and thus also DN 300 fittings in a d 355 mm PE pipeline. In addition to the technical advantage of the Unique Flange also approx. 45% of the total installation costs will be saved.
