Engineering ToolBox > PE Pipes - Temperature and Pressure Rating
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 20 | |
| 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 |
