RE: Thermal Relief for HDPE line
min and max. design temp, volume, lenght, size of system?
Is it in the sun?
greetings
RE: Thermal Relief for HDPE line
design temp = 83degC
yes this is exposed to the sun.
this is just a 50mm line

95C is a common maximum temperature rating for HDPE. Melt is 210 C.

A very low E mod. at 900 MPa means that fluid thermal expansion is absorbed by the pipe for very little force. Remember that the HDPE has a high expansion rate too.

the HDB at 60C is 1/2 its 23C rating.
