machinery feature | PVC-O pipe The $55m investment will pay for a 17,000 sq ft
expansion, allowing the company to expand the size of both the UPVC and PVC-O pipe that it supplies for pressure and sewage applications. Ipex says the expansion will allow it to provide
Western provinces with North America’s largest diameters of PVC-O piping, which is designed to be lighter than standard pipe while providing increased strength and durability. According to the company, PVC and PVC-O continue
Molecor continues to make PVC-O pipe in ever widening diameters, and has updated its technical
manual on the subject
The defined parameters are: safety
coefficient used in the calculation; working pressure – which has been reduced, and not reached an optimum result; height of the cover above pipe crown – which has been modified, rendering the safety coefficients unsatis- factory; nominal pressure – using the maximum nominal pressure (PN25), and unsatisfactory safety coefficients; bedding angle – calculated with the maximum bedding angle (180°) and unsatisfactory safety coefficients; and traffic – including cases with concentrated traffic loads, no concentrated traffic loads, or distributed traffic loads. The company recently expanded its range of TOM pipe, with the launch of a PVC-O pipe of DN 125mm. Prior to this, it had earlier launched PVC-O pipes in DN 500, 630 and 800mm versions. The company says that its molecular orientation
process imbues the pipe with exceptional mechanical and hydraulic characteristics compared to other materials: a higher hydraulic capacity, enabling the conveyance of higher volumes of water for the same diameter; light weight, meaning that heavy machinery is not needed, even for larger diameters up to DN 250mm; and better water hammer behaviour, due to its lower celerity and high impact resistance. To reflect the expansion of its product line, the
company has also updated its technical manual for the design of use of its TOM pipes in water networks. The 190-page guide includes extensive details on the production technology, guidelines to calculations, design and troubleshooting tips, and a number of case studies and design examples.
Stretching production Ipex, a Canadian manufacturer of thermoplastic pipe, recently expanded its plant in Edmonton – part of which will boost production of PVC-O pipe.

to be the materials of choice for municipal and com- mercial projects in Canada because of their unrivalled corrosion resistance, hydraulic performance and ease of installation. Ipex says that its Bionax PVC-O pipe, originally manufactured at the company’s Montreal plant, has the lowest carbon footprint of any municipal piping system – and will be available to Western Canada in the autumn. It will be offered up to 30in diameters – the world’s largest, says the company – and in three pressure classes. It will be supplied
into the water distribution and transmission markets across Canada. “Alberta has been a strong proponent of our piping
systems as a responsible choice for sustainable infrastructure for many decades,” said Alex Mestres, chief executive officer of the Ipex Group. As well as three new PVC and PVC-O lines, 15 local full-time employees – including PVC extrusion line operators, design engineers, and quality control and maintenance workers – will be joining the Edmonton plant. Last year, it launched its Bionax SR pipe – a PVC-O pipe designed for seismic regions. It combines the usual strength and toughness of a PVC-O pipe with the benefits of an extended bell. The result is a pipe with the ability to absorb greater lateral ground strain caused by seismic events. The company spent the preceding two years testing and validating the concept at Cornell University.
In the pipeline Wavin of the Netherlands has highlighted two recent case studies that show the potential application of PVC-O pipe. In the first instance, Dutch water company WMD
installed a 50 kilometre pipeline in the Hunze-valley, through the Drentse Monden area. The pipeline connects the water preparation plants in the cities of
