Advantages

Advanced plastic pipe systems offer major advantages over traditional materials for stormwater applications.

Features Benefits
Light weight Savings on Freight and Handling, due to the light weight of Iplex's PVC-U Stormwater pipes and fittings. 
High flow rate

Iplex’s PVC-U pipe systems have an unrivalled hydraulic capacity due to the extremely smooth bore and precision joints. Flatter grades are possible using PVC-U pipe systems.

Flammability PVC-U does not support combustion.
Non-conductivity PVC-U is a non-conductor of electricity, and is therefore not subject to galvanic or electrolytic corrosion.
Tree root Intrusion resistance Properly made solvent weld joints have been shown to have excellent resistance to the tree root intrusions that cause blockages and infiltration in other systems.
Fittings range The Iplex PVC-U stormwater system contains a complete range of adaptors to enable connection to a wide range of downpipes and other pipe systems.
Low installation cost The light weight of Iplex Stormwater pipes together with longer pipe lengths flexibility and the use of narrow trench widths significantly reduces installation costs, the major portion of the total in-situ costs.

Chemical Resistance

PVC-U pipes have high resistance to a wide range of chemical reagents. Such resistance, however, is a function of temperature, concentration and pressure.

In general, PVC-U is suitable to convey strong acids, alkalis and aqueous solutions (except those which are strongly oxidising), aliphatic hydrocarbons, fluorides, photographic and plating solutions, brine, mineral oils, fats and alcohols. The suitability of a pipeline for conveying a certain chemical will depend on such factors as the concentration of the chemical in the fluid to be conveyed, temperature, flow rate, the presence of pockets or “dead spots” in the pipeline and other factors.

Colour and Markings

Some Iplex stormwater pipe and fittings contain a percentage of recycled material when manufactured, consequently colour can vary, however, most pipe manufactured is white in colour. Stormwater pipe and fittings contain a UV absorber (Tio2) and can be installed in direct sunlight.

Iplex stormwater pipe is branded in accordance with AS/NZS 1254, which includes the date and place of manufacture.

Environmental Credentials

Iplex PVC-U non-pressure stormwater pipe is certified to confirm to the Best Environmental Practice PVC (BEP PVC) provisions of AS/NZS 1260.

The Green Building Council of Australia (GCBA) has defined the standards for best practice environmental performance for PVC manufacturing, against which Iplex’s processes have been audited by an independent certifying body. These permit users of Iplex PVC-U non-pressures pipes to claim positive PVC Credit Points under the GBCA’s Green Star Rating Scheme Learn More.

Iplex Pipelines have published verified Environmental Product Declaration (EPD) on our range of PVC-U non-pressure Pipes. EPD’s are third party certified documents based on ISO 14025 and EN 15804 Standards that communicate transparent and comparable information about the life-cycle environmental impact of a product or service. Specifically, product declarations include information on the environmental impact of raw material acquisition, energy use and efficiency, composition of materials and chemical substances, emissions to air, soil and water and waste generation.

FAQ

Frequently Asked Questions

Can stormwater pipe be installed in sunlight?

Yes. Stormwater pipe and fittings contain UV absorber (TiO 2) and can be installed in direct sunlight.

How deep or shallow can you bury stormwater pipe?

Refer to AS/NZS2566 and AS/NZS2032.

Can I use stormwater pipe to transfer drinking water?

Can I concrete encase stormwater pipe?

Yes. Refer to AS/NZS2032.

What pressure do I test to?
Refer to AS/NZS2032.
What is a safe span if installed above the ground?
