PPN- The Leading Source of Industry News on Polymer Pipes and Plastic Pipe Failure

Plumbing Pipe Failures Around Australia Accelerate the Development of More Oxidation Resistant Plastic Pipes
As a result of the large range of water temperature and chlorine levels encountered across Australia we have seen more PB and PEX plumbing pipe failures recently particularly in WA, NT and QLD.  In response new pipes made from higher classification polymers have been developed which will withstand higher levels of chlorine, temperature and pressure over time.  PIPA POP018 provides guidelines on the suitable application zones based on specific drinking water conditions at a location (considering local average water temperature, chlorine and pH levels).  Plastics Industry Pipe Association (PIPA) POP018 “Polyethylene Drinking Water Pipes in Contact with Chlorine and Chloramine Disinfectants” outlines the Chlorine Classification (CC) Index set out in the US ASTM Standard D3350:2014 “Standard Specification for Polyethylene Plastics Pipe and Fittings Materials”.

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.
