Recycled Plastics Pipes a Big Focus of Ozpipe XIX Conference (Sydney Australia November 7th and 8th 2019)
From the USA, three Ozpipe XIX presenters, Dr Michael Plumier, Mr Daniel Currence and Mr John Kurdziel, will examine the performance requirements of recycled plastics for use in highway culvert and storm drainage pipe applications, its environmental impact and engineering implications. 
Meanwhile, Ozpipe XIX presenter, Dr Andreas Frank of the Polymer Competence Centre in Leoben Austria, will address the issues surrounding the inclusion of recycled material in polyethylene pressure pipes.
From closer to home, Australian Vinyls’ Technical Manager, Nigel Jones, will present a paper detailing the environmental and social benefits of including recycled PVC in sandwich construction drainage pipe.
“A significant portion of the Ozpipe XIX program is dedicated to plastic recycling and the circular economy. This is undoubtedly a reflection of the importance of environmental issues to pipe asset owners, manufacturers and government policy makers,” Mr Connolly CEO of PIPA said.

ExcelPlas Lab Specialising in HDPE Pipe Condition Monitoring, Failure Analysis and Testing
In the event of a HDPE buttweld or electrofusion weld failing during initial testing, or in service, we can conduct investigations to assist in identifying the root cause of the failure.
This service also extends to the premature failure of the pipe or fitting itself.

ExcelPlas Pipe Testing is a Leader in the Field of Polyethylene (PE) and High-Density Polyethylene (HDPE) Testing
ExcelPlas is accredited with the National Association of Testing Authorities (NATA) for butt weld tests, bend and tensile tests, peel decohesion tests on electro fusion sockets and failure mode determination

ExcelPlas Poly Pipe Weld Inspection Lists Top 7 Causes of Weld Failure:
• Lack of scraping
• Inaccurate scraping
• Contamination from dirt, water, oil or clays
• Lack of Paralell-ness of fusion faces
• Misalignment of surfaces
• Time, temperature and pressure deviations
• Not adhering to cool times

We have extensive experience in inspection of poly pipe welds for assuring welded joint quality.  Direct Poly Pipe Inspection ensures that operators are following the proven welding procedure; this reduces the occurrences of operational errors which lead to defects such as inclusions, lack of fusion (LoF), porosity and misalignment.
