The colours and uses of MDPE explained

MDPE is used in dozens of different ways. Discover the different uses and colours of MDPE, and where you use them.

MDPE pipes are a major product as no matter what size contract you are working on, MDPE will always come into play, where it be an irrigation system or a hydro scheme. At JDP we offer a full range of pipeline products for water, gas and barrier pipe systems. Referred to as MDPE (medium density polyethylene) these plastic pipes are used as a replacement for traditional copper pipes, saving time and cost on installation.

Ultimately, anywhere where there is a tap, you are going to need a water supply so these products are a basic, but a vital component in any project. From distilleries to construction sites MDPE is almost certainly playing a part, so it’s important to know the differences in the product we offer and where you can use them in your project.


Blue MDPE This lightweight pipe is available in coils of 25m, 50m, 100m and 150m for ease of use, and comes in sizes ranging from 20-63mm. The benefits of using MDPE over copper is that it won’t corrode, meaning it is ideal for delivering clean (potable) water services. It also has a good resistance to a wide range of chemicals.

Black MDPE

Black MDPE

This colour MDPE is used to carry non-drinking water; dirty, industrial or irrigation. It can be installed above ground. It can also be used as a pumping main for sewage plants. It is not prone to rot, corrosion, stress cracking making it suitable for the above ground conditions you would expect. Also available in sizes 20-63mm in coils of 25m, 50m 100m and 150m.

Yellow MDPE


Yellow pipe is used for below ground gas distribution to household meter boxes. It is suitable for natural gas and LPG. Available at JDP in 25mm and 32mm sizes with an option of 50m or 100m coils.

Barrier pipe MDPE

Barrier pipe

This pipe is a multi-layer system which includes a black PE inner core, a protective aluminium layer and an outer layer of PE. The pipe is mainly blue but will have brown vertical lines running along the pipe and an internal black colour. It is used to eliminate the migration or pollutants into drinking water through the clever combination of the 3 layers within the pipe. This is especially useful in:

  • construction near industrial zones
  • agricultural areas
  • cemeteries
  • landfill sites
  • petrol stations
  • military land
  • crossings at rivers
  • brownfield development sites
  • areas which are prone to flooding

Industrial water/ Sewage pump MDPE

Industrial MDPE

MDPE which is black with two orange lines running along is to be used above or below ground, to carry industrial or sewage pump main water.
