PE Pipes and Dimensions

PE pipe dimensions according European Standards

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 (lb_f/in²) = 10⁶ dyn/cm² = 750 mmHg
