hdpe pipe sizes and dimensions

polyethylene pipe sizes or Dimensions - Sizes and dimensions of pipes and tubes, and their fittings - inside and outside diameter, weight and more

PE100 can be manufactured in a wide range of pipe diameters from 16mm to 2000mm. Even larger diameters are possible with the development of appropriate extrusion dies. However the common range of pipe sizes is from 32mm to 1200mm.


Nominal diameter of a PE100 pipe is its external diameter, not its internal bore diameter.

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.

Standard diameters in this range are:

32 mm	63mm	90mm	110mm
125mm	160mm	180mm	225mm
250mm	280mm	315mm	355mm
400mm	450mm	500mm	560mm
630mm	710mm	800mm	900mm
1000mm	1100mm	1200mm

The internal bore diameter for each of these sizes will depend on the SDR of the pipe. Non-standard pipe sizes can be manufactured for specific applications if necessary.

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 (lb_f/in²) = 10⁶dyn/cm² = 750 mmHg
