DPI Plastics to highlight critical role of standards at SAPPMA conference


SAPPMA Pipes IX Conference 8th September

The critical role that the South African Plastic Pipe Manufacturers’ Association (SAPPMA) plays in upholding SABS/SANS certification in the industry will come under the spotlight at Pipes IX on 8 September at the Bytes Conference Centre in Midrand.

DPI PLastics to highlight role of SAPPMADPI Plastics technical and product manager Renier Snyman will be addressing this topic under the banner of ‘A passion for quality’. Snyman says it is vital for SABS/SANS standards to be upheld in the industry.
“It is important to ensure that all products are compliant, particularly given that July 2015 was the final deadline for all local manufacturers to adhere to the latest SABS requirements in terms of phasing-out lead-based stabilisers in the manufacture of PVC pipe and fittings,” Snyman reiterates.

DPI Plastics was not only one of the first adopters of the new requirements, but has also driven the necessary amendments of the related SABS specifications.
These are related to both pressure and sewerage PVC pipes and fittings. The company now utilises organic-based stabilisers as a lead substitute in its manufacturing process.

“DPI Plastics actively advocates building a greener tomorrow for our future generations,” Martine Goodchild, marketing manager at DPI Plastics, comments.

PVC pipe from DPI Plastics adheres to the latest quality and environmental standards“This not only refers to what goes into a product, but also refers to how it is made: for example, energy efficient, resource efficient and cleaner production with a high recycling level. We live this ethos, and encourage other manufacturers to do the same,” Goodchild comments.

At last year’s SAPPMA conference, DPI Plastics highlighted its ‘how-to’ guide on field pressure testing to ensure that the integrity of a pipeline is not compromised as a result.
Modern plastic pipes are manufactured under controlled conditions. The testing regime at the manufacturing facility includes hydrostatic pressure testing of pipes and joints.
This ensures that they are capable of delivering on minimum performance requirements. When the pipe is laid on-site, however, the manufacturer is not in control of the joining process.
Field pressure testing is therefore used to test the integrity of pipe joints completed on-site, in accordance with SANS 2001:DP2 – Medium pressure pipelines standard.

DPI Plastics has compiled a handy guide covering all aspects of field pressure testing, in order to standardise the varying interpretations of the requirements by different installers and engineers.

“The most commonly misinterpreted test parameters are pressure, duration and length,” Snyman notes.
Pipes IX will feature an opening address by SAPPMA CEO Jan Venter, while the keynote address will be delivered by economist Mike Schussler. Professor Kobus van der Walt from North-West University will be delivering a paper outlining South Africa’s looming water crisis.
