PE Pipes - Temperature and Pressure Rating

Maximum operating pressure of Polyethylene - PEH - pipes depends on temperature

The operating pressure of PEH pipes depends on the temperature.

Note that the PN rating of polyethylene - PE - pipes is based on temperature of 20oC.

Temperature
(oC)
Maximum Operating Pressure (bar)
PN 6 PN 10 PN 16
20 6.0 10.0 16.0
30 3.2 8.0 13.0
40 2.0 6.0 11.0
50 2.6 4.0 8.0
60 1.0 3.2 6.0
