Penstocks

gamme_vannes_murales

Our penstocks are specially designed for holding wastewater and stormwater.

TECHNEAU offers two ranges of penstocks :

  • Galvanized steel
  • Stainless steel

They usually incorporate in books such as :

  • Wastewater treatment plant
  • Storm water tank
  • Retention Basin Storm water
  • Storm water or wastewater network
  • Manhole
  • Particulate and / Decanter or oil separator

Operation (watertightness)

Two types of watertightness are defined to determine a penstock

watertightness UPSTREAM

watertightness DOWNSTREAM

Our ranges (HydroVE Hydro VM Hydro VL)

watertightness UPSTREAM :

Nos gammes (HydroVE, HydroVM, HydroVL)

HydroVE

Penstocks are watertight upstream and downstream. Watertightness is provided upstream an installation either upstream or downstream of the item.

HydroVM

Penstocks are watertight upstream and downstream of Dn 200 to Dn 500. Penstocks Dn Dn 600 to 1200 are watertight upstream. Watertightness is provided within an installation upstream of the item.

HydroVL

Penstocks with shovel HDPE watertight upstream.
