EN 1401 Underground Drainage

What is Underground Drainage?  UG (KG PVC-U)

They are plastic pipes and fittings systems made of polyvinylchloride (PVC-U), with diameters from DN110 to DN500 mm. KG PVC-U system has been designed to construct household sewage and drainage systems, to collect rainwater.

KG PVC-U Sewage Piping System Characteristics

  • The pipes are produced in ring stiffness classes SN2, SN4, and SN8.
  • Meeting the requirements of LST EN 1401-1 and LST EN 13476-2 standards.
  • Pipes and fittings seals are mounted at the factory and made of styrene butadiene rubber (SBR).
  • The tightness of this non-pressure underground system provides for a maximum pressure of 0,5 bar (5 m H2O) at the temperature of 20oC.

KG PVC-U Sewage Piping System Advantages

  • Completely resistant to general and pitting corrosion.
  • Resistant to harmful chemicals and activity of subterranean waters, and currents.
  • Very lightweight.
  • High wall smoothness.
  • Resistant to sediment forming on internal surfaces of the walls.
  • Microbiological resistance.
  • Long operational life is estimated to be around 100 years.
  • Fast and easy assembly.
  • It can be combined easily with other materials.
