What range of pipe dimensions is available?

Quick access

PE100 can be manufactured in a wide range of polyethylene 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.

Diameters of PE100 pipe in this range are (mm):

32

40

50

63

90

110

125

140

160

180

200

225

250

280

315

355

400

450

500

560

630

710

800

900

1200

 


 


 


Diameters shown in red are non-standard diameters available to order.

For PE100-RC the available diameter range is DN90-630.

The internal bore diameter for each of these sizes will depend on the SDR of the polyethylene pipe. Non-standard PE100 pipe sizes can be manufactured for specific applications if necessary.

PE pipe length

PE pipe manufacture is a continuous process therefore in theory the lengths available are unlimited. In practice however the lengths are limited by transport, ease of handling on site, other general site conditions and local practices.

PE100 pipe is generally available in three forms

  1. Straight lengths of pipe (diameters 90mm and above) in standard lengths of 6, 10, 12, 15, 24, and 30 metres. For some special projects, e.g. sea outfall installations, where transport can be made by water (canal, river or sea), extremely long lengths can be supplied.
  2. Coils. Free-standing coils of pipe up to pipe diameter 180mm.
  3. Drums. Similar to coils but supplied wrapped onto a drum for support. Longer lengths are available in this form than in coils.

For both coils and drums the range of pipe lengths available is usually limited by transport considerations.

The table below shows the typical range available. However specific requirements should be discussed with the pipe manufacturer.
