PVC-O pipe | machinery feature
Pipe made from oriented PVC (PVC-O) is
becoming a more popular choice for pressurised applications, thanks to its combination of strength and lightness. Lou Reade reports
PVC-O proves tough enough
Though oriented PVC (PVC-O) is still very much a niche product, it is gaining in popularity through the efforts of a small number of suppliers – and recognition that it can solve problems that are beyond other piping materials. At the forthcoming K2016 show, PVC-O specialist
Molecor will present its M-OR-P 5012 system, for making Class 500 PVC-O pipes up to DN1200mm. At the same time, it will showcase a new range of PVC-O fittings for its pipes. The company will present more details at the show.
Calculated approach Molecor has also improved the functionality of its TOM mechanical calculation program (available online at
www.tomcalculation.com). TOM is a personalised platform that helps users to
create their own projects and associated calculations. The application calculates the different forces that the

company’s TOM pipes will withstand, as well as their breaking and compression safety coefficients, based on two reference standards: ATV-DVWK-A 127E:2000 ‘Static Calculation of Drains and Sewers’; and a similar Spanish standard, UNE 53331:1997. Performing these mechanical calculation on buried pipelines helps engineers to assess the mechanical stress transmitted to the pipe by the action of the different external loads – so should be done in advance of installation. The application is intuitive, and gener- ates a full report with the results of all the calculations – recommending the most suitable pipe for each installation. The latest version adds a new section, called “Changes for validation”. If results obtained in the report do not satisfy the conditions of the selected safety coefficients – or the pipe’s maximum admissible deformation – the application can change different parameters in order to obtain a valid installation.
PVC-O pipe is light enough to install without the need
for heavy machinery
