HDPE pipes or PE pipes are a new generation of plastic pipes used for transporting clean water, irrigation water, sewage, gas, sludge, chemicals and other wastewater. HDPE pipes are made of high-density polyethylene, which makes them stronger than other piping systems. These pipes are unique because they do not need to be glued during connection, with very low maintenance and repair costs. PE pipes can withstand considerable pressure, making them the pipe of choice for fluid transfer. HDPE pipes for sale in Kenya are available fromGreek private company. Leveraging the benefits of polyethylene, Grekkon Limited works with HDPE pipe manufacturers in Kenya to produce the highest quality PE pipe for a wide range of applications.

Advantages of HDPE pipes compared to other piping systems

  • They are resistant to chemical corrosion. PE pipes do not corrode and do not support biological growth. Resistance to chemical corrosion makes them ideal for burial. Corrosion resistance makes them the best water pipes for the transport of highly corrosive acids and alkalis.
  • HDPE pipesthey are flexible and lightweight. Pipes can be bent relatively easily to radii of 30 m and more
  • The pipe is available in long lengths of 12 m, 50 m and 100 m compared to PVC and GI pipes which have a maximum length of 6 m. This reduces the number of connections. Custom lengths over 100m are also available for pipe diameters of 16mm, 25mm, 32mm and 40mm.
  • Less friction due to fewer connections.
  • They are resistant to wear due to good physical strength.
  • The best resistance to UV radiation compared to PVC, making it easier to expose them to the surface.
  • HDPE is smooth on the inside, so they have less friction loss. This reduces pump costs.
  • The connections have no leakage thanks to the techniques of butt welding and compression fittings used. Thermal fusion ensures that the joints are as strong as the pipe itself. The fusible joints are self-locking, so no pressure blocks are required.
  • Great strength.
  • Very efficient in hydraulic systems.
  • Low maintenance costs compared to other piping systems.
  • It is recyclable and environmentally friendly.

Disadvantages of HDPE pipes

  1. High thermal expansion. HDPE pipe breaks easily when exposed to extremely high temperatures. This can lead to pipe replacement
  2. Poor weather resistance.
  3. Flammable. The pipe is not fireproof and will burn out if necessary.

Application of HDPE piping systems.


HDPE irrigation pipes are widely used in agriculture for irrigation. Practicing farmersdrip irrigationIabove ground sprinkler systemsthey find them easy to process compared to PVC and GI pipes. Due to the fewer connections, these are the preferred pipespump waterover long distances of rivers andreservoir dams. They also work in wellwater from the wellnet.

How HDPE pipes are connected

Mechanically using HDPE fittings

HDPE water pipe fittings or PE compression fittings are often used to connect pe pipes up to 90 mm. HDPE water supply fittings are most popular due to less technical aspects associated with their use. containconnectors and elbows.

leave electrofusion

During electrofusion welding, welding is performed using heating resistors in the fitting. After placing the tubes in the EF fittings, the ends of the welder are connected to the EF fitting resistors and heated. This is how the HDPE pipe is connected to the electrofusion fitting. Pe 100 pipes can be electro-welded with HDPE pipes with a diameter of 20 mm to 1200 mm.


The butt welding method is the most commonly used welding method to connect HDPE pipes and fittings. Here, the two ends of the tubes are heated and welded with a butt welding machine, and the two ends are pressed together under pressure at a certain temperature. The resulting joints are as strong as the pipe itself. HDPE pipes with a diameter of up to 1200 mm can be welded.

How to choose HDPE pipe

There are always several factors to consider before purchasing PE pipes, including the application, pressure requirements and color coding on them. Below you can read what to check.

PE pipe pressure gauge chart (for Kenyan market)

PE pipes are manufactured in different pressure classes (PN classes), which indicate the pressure in bar that the pipe can withstand in water at 20 degrees Celsius. Here are the different pressure classes according to international standards to check with your engineer or technician.

  • PN 6 = max. pressure 6 bar
  • PN 8 = max. pressure 8 bar
  • PN 10 = max. pressure 10 bar
  • PN 12.5 = max. pressure 12.5 bar
  • PN 16 = max. pressure 16 bar
  • PN20 = max. pressure 20 bar
  • PN25 = maximum pressure 25 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) = 106dyn/cm2 = 750 mmHg

Due to the wide pressure range, all types of pumps usually work well with these water pipes. The best examples areElectric booster pumps,electric submersible pumps, low andhigh pressure dieselIpump gasoline.Solar powered water pumpsthey also work well with PE pipes.

How to install HDPE pipes

  1. Digging trenches. Dig trenches as directed by engineers. The slots should be as flat as possible to prevent damage to the pipes. Avoid sharp turns and winding ditches.
  2. Pipe location. For rolls of 50 m and 100 m, the pipe is carefully unrolled before installation. For pipes of 6 m and 12 m, for pipes with a diameter larger than 110 mm, the pipes are first joined by butt welding. After the connection is completed, they are placed in the grooves. Assembly can be manual, manual or machine. Pipe bending is common during installation. To restore the pipes to their original shape, pour hot water or step on the kink on a sunny day.
  3. Fill and compact. This is to protect the pipe from external damage. Remove hard objects that can also damage pipes when backfilling.
