Is Your PEX Pipe a Quality Product? Get it Tested!
With PEX Pipe it is critical that there is consistent and uniform crosslinking throughout the entire pipe wall during the manufacturing process since this improves performance properties such as optimal thermal memory, elasticity, elevated temperature strength, chemical resistance, environmental-stress-crack resistance, slow-crack-growth resistance, and abrasion resistance.  ExcelPlas can test the degree of cross linking through the wall thickness of the pipe.  Despite the flexibility of PEX piping and being highly resistant to breakage it can undergo brittle cracking in service due to exhausted antioxidant reserves.  PEX piping is an easy-to-install alternative to copper pipe however quality assurance checks should be done on PEX pipe particularly that imported from Asia.   ExcelPlas Labs use a range of analytical techniques to assist all stakeholders (Building Owners, Facility Management, Body Corporate, Insurance companies, Plumbers and Hydraulics Engineers) to better understand the composition, quality and durability of imported PEX piping.  Our fully trained professional staff can conduct in-situ sampling on site and sampling of provided reference pipes (from spare rolls or off-cuts).  Contact ExcelPlas Labs to assess the quality of PEX piping.

Australian Test Lab Specializing in Quality Assurance Testing of Butt Welds (ISO 13953) and Electrofusion Welds (ISO 13954)

ExcelPlas Labs Offer Global Pipe Failure Investigations
ExcelPlas Labs have created a new benchmark in failure analysis of HDPE, PP-R, PB and PEX pipes in addition to PVC &  CPVC pipes as well as composite GRP and GRE pipes.  When a plastic pipeline fails to perform as intended, our team can determine the root cause of failure (e.g. oxidative failure, chemical failure, creep failure, over-stress failure, fatigue failure, design failure, etc).  ExcelPlas are experienced with all plastic piping failure modes and mechanisms including Slow Crack Growth (SCG) Rapid Crack Propagation (RCP), Environmental Stress Crack Resistance (ESCR), Oxidative Stress Cracking (OSC), cyclic fatigue, manufacturing defects, and polymer material problems.

ExcelPlas – the Australian Pipes & Fittings Testing Laboratory

  • Accredited to ISO 17025 by the National Association of Testing Authorities (NATA) Australia, and is Australia’s largest laboratory dedicated for the testing of plastic pipes and fittings to various Standards which include Australian, European and International Standards.
  • The staff employed at the laboratory have a combined experience of more than 85 years within the plastics industry specifically with manufacturing, quality control and the research and development of plastic piping systems including HDPE, PEX, PP-R, PVC, U-PVC, M-PVC, O-PVC, ABS, GRP, GRE and PB.
  • Services provided include conformance testing, compliance testing, batch release testing, root cause analysis for field failures and non-destructive testing of samples.

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.
