PVC pressure pipes are manufactured from PVC resin compounded with stabilisers, lubricants and pigments. They do not contain any plasticisers and hence are known as unplasticised PVC or PVC-U.

PVC-U pipes have been used for pressure applications in Australia since the 1960’s, but have a much longer service history elsewhere in the world. Over this time, industry has recognised the many benefits of PVC for pressure pipes: material stability, immunity from corrosion, high strength to weight ratio, ease of handling and installation and excellent flow characteristics.

Further developments in PVC pressure pipe technology has led to the introduction of Oriented PVC (PVC-O) and Modified PVC pressure pipes (PVC-M).

PVC is the most commonly used pipe for water reticulation by Australian water agencies. It is used extensively in irrigation and industrial applications.

The size range for PVC pressure pipe in Australia typically extends to 600mm (DN600)
