Effect of Temperature Change
Working Pressure
The standard design temperature for HDPE pipes is 20°C and working pressures are
usually quoted for this temperature. HDPE pressure pipes function perfectly well
below 20°C right down to freezing point and can in fact, withstand higher pressures
than those quoted at 20°C.
As can be seen from the stress regression lines, the creep rupture strength
diminishes with increasing temperature and working pressures must be down-rated
if the same factors of safety are to be maintained.
