Expansion plug DN 250mm - ITINERO

Code article : 248429

Description

The ITINERO expansion plugs are used to temporarily or definitively seal the pipes and fittings located inside the aperture, used on gravity drainage networks. The resistance to accidental pressure of the expanding plug is 0.2 bar without additional device. If necessary, the locking of this plug is carried out by means of the specific grip collar which can accommodate thrust pressures up to 5 bars depending on plug type.

Recommended use :

  • Rainwater
  • Runoff water
  • Corrosive atmosphere

Major benefits :

  • Performances guaranteed with marks delivered by third party.
  • Long lifetime with high resistance to climatic stresses due to the zinc coating and the low thermal expansion coefficient of cast iron.
  • Low maintenance due to the best in class resistance to shocks and crushing.
  • High level of fire safety.
  • Suitable to many bridge and tunnel design and adapted to renovation projects.
  • Easy to install due to mechanical couplings assembled with simple tools.
