ISO 4427 - PE Pipes for Water Supply - Dimensions
Polyethylene pipe dimensions according European Standards.
Polyethylene - PE - is popular material and and commonly used as water pipes in the PE 50, PEH or PE-HD (PolyEthylene High Density) qualities.
PE pipes are produced in different pressure grades - PN grades - indicating the pressure in bars the pipe supports with water at 20 oC.
Pressure grades according to European standards:
- PN 2.5 - max pressure 2.5 bar
- PN 4 - max pressure 4 bar
- PN 6 - max pressure 6 bar
- PN 10 - max pressure 10 bar
- PN 16 - max pressure 16 bar
- 1 bar = 105 Pa (N/m2) = 0.1 N/mm2 = 10.197 kp/m2 = 10.20 m H2O = 0.9869 atm = 14.50 psi (lbf/in2) = 106 dyn/cm2 = 750 mmHg
