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 or recycled layer sandwiched 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 significantly less embodied energy compared to solid wall pipe equivalents.
Sizes in Australia are typically available up to 600mm (DN600).
