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).
