DPI Plastics upgrades large-bore extrusion line for new Ultraflo range
DPI Plastics has upgraded the tooling on its large-bore extrusion line at its Roodekop facility in Johannesburg to extend its current range of Ultraflo PVC-M pressure pipes , including diameters of up to 630mm and a 16-bar maximum operating pressure .
The Ultraflo range has been expanded due to a demand in the market for large-bore pipes with higher operating pressures , comments DPI Plastics technical and product manager , Renier Snyman . “ Our PVC-M pressure pipe range is the only one in sub-Saharan Africa to include 630mm diameter pipe up to a 16-bar operating pressure .”
Ultraflo PVC-M , or mPVC , is a tough and resilient , modified PVC pressure pipe , developed to offer greater strength and toughness . Modified polyvinyl chloride has been designed specifically to provide similar tensile strength and greater resilience than standard PVC piping products . It is ideally suited to bulk water supply projects due to it being considerably more ductile than industrystandard unplasticised polyvinyl chloride . The enhanced ductility of PVC-M pipe gives it exceptional resistance to crack propagation under pressure .
In addition to superior toughness , PVC-M has reduced wall thickness . This translates into less raw materials during the manufacturing process , and ultimately a lighter product that is easier to transport and install , thereby minimising its total carbon footprint .

DPI Plastics has expanded its Ultraflo range due to a demand for large-bore pipes with higher operating pressures .
Ultraflo pressure pipes from DPI Plastics are manufactured in accordance with the SANS 966 Part 2 specification , incorporating a design stress of 18MPa . “ Our pressure-pipe systems offer design engineers and contractors distinct advantages such as a lower mass , higher impact resistance and improved ductility , increased hydraulic capacity , and predictable performance ,” Snyman concludes . u
