Pressure Nominal (PN) Rating is a standardized classification system defining the maximum allowable operating pressure for piping components at 20°C, essential for system design and material selection.
Rating Classifications
| PN Rating | Pressure (bar) | Application |
|---|---|---|
| PN6 | 6 bar/0.6 MPa | Gravity/Low pressure |
| PN10 | 10 bar/1.0 MPa | Standard distribution |
| PN16 | 16 bar/1.6 MPa | High distribution |
| PN20 | 20 bar/2.0 MPa | Industrial systems |
| PN25 | 25 bar/2.5 MPa | High pressure |
Material Correlations
| Material | PN Rating | SDR Value |
|---|---|---|
| PE100 | PN16 | SDR 11 |
| PE100 | PN25 | SDR 7.4 |
| PE100 | PN10 | SDR 17 |
| PVC-U | PN16 | Series 8 |
| HDPE | PN16 | SDR 11 |
