High Impact Strength – The high impact strength of PE pipes ensures resistance to the rigours of pipe laying conditions.
Damage Resistance – PE has low notch sensitivity, providing a high level of resistance to the effects of external damage, especially important for pipe bursting operations and others where there is a likelihood of such damage.
Abrasion resistance – PE pipes have excellent abrasion resistance providing long life in abrasive slurry applications.
Chemical resistance – Outstanding resistance to a wide range of chemical reagents allows the use of PE systems in tailings pipelines and chemcial treatment applications used in mining operations.
Corrosion Resistance – PE pipes are highly resistant to corrosion and do not require any protective coatings or other corrosion protection systems.
Weathering Resistance – PE pipes are stabilised against ultraviolet (UV) light degradation by the inclusion of carbon black in the raw material. Black PE pipes are, therefore, suitable for installations where the pipes are exposed to direct sunlight.
Flexibility – PE pipes are flexible and can be curved during installation. This inherent resiliency and flexibility allows the pipe to handle stresses caused by soil movement. This makes the pipes particularly useful in submarine pipe lines, mine subsidence and earthquake prone areas.
Ease of Installation – PE pipes are easy to install with their light weight and long lengths.
High flow capacity – low friction compared with materials such as fibre reinforced cement and resistance to material deposit buildup give PE pipes long lived high flow capacity.
Co-extrusions – PE pipe is available in a range of identification colours that may be either coextruded as stripes or “jackets” that completely surround the pipe. Blue is used for identification of water pipes and purple for recycled water pipes. White jacket are used for minimisation of heat build-up in above ground pipes.
Long Life – Polyethylene pipes have a proven high reliability record across a wide range of industries and applications, now approaching a period of 50 years. PE also provides a long maintenance free lifetime with low whole life costs, compared to many other materials.
Trenchless construction – Due to their inherent characteristics, PE pipes can be used in slip lining, pipe bursting, directional drilling and micro-tunnelling. These save significant cost and environmental disruption in water supply and sewerage applications.
