PE PIPE DIMENSION

Polyethylene - PE - is popular and and commonly used material in water pipes. It is usual to use the PE 50, PEH or PE-HD (polyethylene high density) quality.




PE pipes are produced in different pressure grades - PN grades - indicating the pressure in bars the pipe can support with water at 20 oC.



The pressure grades available according to European standards are



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
