Standards Australia Unwarranted Push to Ban All Plastic Pipes Below PN16 From Hot Water Applications in Australia and New Zealand (Breaking News)
In the new draft of AS3500.4, recently released for Public Comment, a new clause 2.5.2 (h) has been quietly added that requires ALL hot water piping to have a minimum PN16 rating. The current AS3500 Standard already dictates that piping must meet an operating pressure of 1.0MPa at 60 deg C. Long standing PN12.5 rated polymer pipes meet this requirement and have performed without fail for more than a decade both in Australia and New Zealand. PPN and many of the PEX pipe manufacturers see absolutely no reason to include this new clause.

ExcelPlas Labs 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 Strain Hardening Test (SHT) for HDPE Pipes
The SHT in accordance with ISO 18488 is a relatively new, but excellent way to obtain a rapid indication of the Stress Crack Growth (SCG) resistance of your piping material. This tensile test performed at 80°C has become in just a few years the new standard for Batch Release Testing (BRT). And not without reason.  The test requires only a very small amount of material, the results are very reliable with a very low inter-laboratory scatter and the results are available within a few days, regardless of the PE grade. The SHT is usually performed on resin material but it can also be performed on samples taken directly from pipes or sheets. As accredited lab, EXCELPLAS is happy to discuss the possibilities with you, whether it is for BRT, benchmarking, quality control of your (high performing) PE grade or for polymer compliance/ validation.

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.
