Resistance to radioactive effluents
There is no risk of damage as a result of slightly radioactive water. However, please ask
our Technical department for more information relevant to the particular application.
Resistance to abrasion
Drainage systems are increasingly becoming hidden refuse chutes. A pipe’s resistance to abrasion is
a particularly important factor in branch pipes, soil stacks and ground pipes. Geberit HDPE is highly
resistant to abrasion and its extra thick walls offer additional protection.
Thermal expansion 0.17mm/m.K
Heat expansion of Geberit HDPE is relatively high. As a rule of thumb, for every 50°C increase
in temperature, an expansion of 10mm per linear metre of pipe can be anticipated.
Resistance to hot water
Geberit HDPE can be safely used as a waste pipe with continuous flow temperatures
of up to 80°C and for intermittent discharges of up to 100°C for short periods (maximum
1 minute flow for a maximum of 400 times per year).
Resistance to impact
Geberit HDPE and Geberit Silent-db20 are unbreakable at room temperature. Their resistance to
impact is very high even at extremely low temperatures (down to approximately -40°C) thus meeting
the requirements for externally installed pipes.
Condensation
Geberit HDPE and Geberit Silent-db20 are poor conductors of heat. No condensation
should form during short periods of undercooling. For areas with longer periods of
cooling in high humidity conditions, insulation may be required so please seek advice.
In particular internal rainwater pipes passing through a warm building would benefit
from thermal insulation
