HDPE PIPELINESPolyethylene Pipes

HDPE pipes are durable and flexible and it provides major cost savings. These pipes do not corrode in the environment, and will maintain its flow capabilities because of its smooth bore and end-to-end jointing methods.

HDPE Pipe is hard, light, solid pipe with a smooth inner and outer surface. Transportation of HDPE Pipe requires minimum equipment and is easily applied in all field conditions, on ice or in wet floor, marshy areas.

HDPE Pipelines

Piping made from Polyethylene (PE) is a cost effective solution for a broad range of piping problems in municipal, industrial, marine, mining, landfill, duct, and agricultural applications.

The Popular available type of PE is HDPE (High Density Polyethylene). It can carry potable water, water waste, slurries, chemicals, hazardous waste, and compressed gases. In fact, PE pipes has a long and distinguished history of service to the gas, oil, mining and other industries. It has the lowest repair frequency per mile of pipe per year compared with all other pressure pipe materials used for urban gas distribution.

PE is strong, extremely tough and very durable. HDPE Pipes are more suitable for those who are looking for long service, trouble free installation, flexibility, resistance to chemicals or a myriad of other features.

Molecular chain of Raw Material

Polyethylene (PE) consists of long molecular chains. These molecules may be branched and the degree of such branching and the length of side chains have important effect on the properties of Polyethylene. It’s crystallizes as the melt cools. Parts of the long molecular chains arrange themselves by folding into very small crystallites which are joined together by amorphous regions to form macrostructures known as spherulites. The shorter the chains and lesser the branching, the better the process of crystallization. The crystallization region has a higher density than the amorphous region and therefore different density values are obtained depending on the degree of crystallinity.

HDPE Pipes Saves both Time & Money

Lower life cycle costs

Corrosion resistance

PE is basically chemically inert. This pipe system does not rust or corrode. It resists chemical attack from aggressive soils. There is no need for protective layer or finishing process.

Leak tight

Butt fused joints create a homogenous, monolithic system. The fusion joint is stronger than the pipe. Therefore, unlike ring type joints or the other mechanical jointing systems, there is no risk of leakage resulting from joint distortion.

Optimum flow rates

Smooth inside pipe surface allows for a high Hazen-Williams “c” factor. “c” remains constant throughout the lifetime of the system due to an innate high resistance to scale and biological build up. PE is also biologically inert.

Excellent water hammer

These characteristics designed to withstand surge events. The inherent properties of polyethylene allow the system to significantly lower the effect of surges compared to PVC and ductile iron systems.

Light Weight & Flexible

PE pipe is supplied in straight lengths or in coils. Made from materials about one-eighth the density of steel, it is lightweight and does not require the use of heavy lifting equipment for Installation. It reduces the need for fittings, is excellent in shifting soils and performs well in earthquake-prone area.

Resistance to geological conditions

PE piping systems have inherent resistance to ground temperature fluctuations and earth instability.


Reduced installation costs

  • Material of choice for trenchless technology. Used in directional boring, river crossings, pipe bursting and slip lining
  • Fewer fittings due to pipe flexibility. Allowable bending radius of 20 to 25 times outside diameter of pipe.
  • Lighter equipment required for handling and installation than with metallic materials.
  • Eliminates the need for thrust blocking. Heat fused joints are fully restrained.
  • Light weight and longer lengths allow for significant savings in labour and equipment.
