The system is designed for:

  • SDR 11 pipes - for cold water installations - operating temperature 20°C, pressure - 1.0 M Pa.,
  • SDR 7.4 - for hot tap water installations, operating temperature 60°C, max. pressure - 1.0 M Pa.,
  • SDR 6 – for central heating installations – operating temperature 80°C, max. temperature 90°C, pressure - -0,6 MPa.


SDR – Standard Dimension Ratio

SDR = 2xS + 1 = d / s

S = pipe dimensions series, acc. to ISO 4065

S = (D-s)/2s

D – pipe inside diameter

S – nominal pipe wall thickness

PN – pipe pressure ratio

Hydro-Plast elements are joined using multi-fusion welding (20-200 mm diameter elements) or electrofusion welding . Both methods offer absolute bond tightness.
