PE Pressure Gas Pipe – Yellow

The high impact strength of PE pipes ensures resistance to the rigors of pipe laying conditions.

PE has low notch sensitivity, providing a high level of resistance to the effects of external damage, especially important for pipe bursting operations and where there is a likelihood of such damage.

Vinidex PE pipes have excellent abrasion resistance providing long life in abrasive slurry applications. In most applications, PE outlasts other pipe materials such as mild steel and rubber lined steel.

Outstanding resistance to a wide range of chemical reagents allows the use of PE systems in applications such as tailings pipelines and chemical treatment applications used in mining operations.

PE pipes are highly resistant to corrosion and do not require any protective coatings or other corrosion protection systems.

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.

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.

PE pipes are easy to install with their light weight and long lengths. Polyethylene coiled pipes are widely used in applications such as stock watering, irrigation systems, communications, gas and reticulated water mains.

PE pipes have lower friction factors compared to non-plastic materials such as cementitious linings and fibre-reinforced cement. The surface energy characteristics of PE ensure resistance to material deposit buildup so that the smooth bore is maintained over the working life of the pipeline.

PE pipe is available in a range of identification colours that may be either co-extruded as stripes or “jackets” that completely surround the pipe. Blue is used for identification of water pipes, purple for recycled water pipes and yellow for gas. White jacket are used for minimisation of heat build-up in above ground pipes exposed to sunlight. White co-ex pipes are extensively used in the mining industry.
