Drain, waste and vent pipe as well as stormwater pipe and electrical conduit are manufacturered using either solid wall, structured wall or multilayer construction techniques. Multilayer techniques often incorporate a foamed layer in the core of the PVC pipe.
Modern manufacturing technology enables production of lighter weight PVC pipes than the traditional solid wall PVC pipes, reducing the weight of the pipe by up to 40%. This produces a more material efficient PVC pipe without compromising functionality offering the advantage of having significantly less embodied energy compared to solid wall equivalents.
Recycled PVC is commonly used in the core of multilayer non-pressure pipes, further enhancing their environmental credentials.
Sizes in Australia are typically available up to 600mm (DN600).
Polypropylene has high impact resistance, good stiffness and excellent chemical resistance, making it a good material for the following applications:
Stormwater drainage pipelines
Estuarine and Ocean outfalls
Gravity Sewer mains
Low head Irrigation
Rehabilitation (as liner pipe)
Stormwater retention systems
PP is typically available in Australia to 900mm (DN900)
Often polyethylene pressure pipe is used for non-pressure applications. There is a range of PE pipe specifically designed for non-pressure applications. Primarily, non-pressure PE is used in sewer, drainage and agricultural applications.
When using pressure pipe for non-pressure applications consult the manufacturer.
