adequa URATOP® Class 500 bi-oriented PVC-O pipe system

The solution that delivers maximum efficiency and high performance levels for pressurised water systems


Potable water supply and distribution, pressurised urban water systems, conduits for agricultural infrastructures, irrigation systems for parks and gardens, golf courses, sports centres, pumped waste water systems, water treatment plants, distribution of reusable water, etc.

Principal benefits

  • High impact resistance.
  • Greater hydraulic capacity without changing diameters.
  • Product 100% recyclable.
  • Maximum flexibility.


  • DN 90 mm to DN 400 mm.
  • PN 12,5, 16, 20 and 25 Atm.
