Plumbers Cleared by Investigation into Iplex Pro-fit Pipe Problems

Failed PB Piping in WA – What Happens Now?
The extent to which Iplex® Australia is ultimately held to have any responsibility for the Pro-Fit™ PB-1 pipes failures and the impact that may have on the company is not known at this time. Those matters will depend on resolution of a number of matters, including: (i) the final determination as to cause(s) and the allocation of responsibility between Iplex® Australia and other parties; (ii) the type and scale of remediation required, including the cost of undertaking it; (iii) other losses suffered by third parties ultimately attributable to Iplex® Australia; (iv) if and how any relevant insurance policies respond; and (v) the time frames over which payments may be required. For example, removing Pro-fit from houses in Western Australia may take a number of years to do, given the scale of that task and the constrained resources in the Western Australia market likely to be available to undertake that work. If Iplex® Australia was to become subject to litigation in respect of this matter, final judgment may not be reached for some time i.e. many years.

ExcelPlas Pipe Condition Assessment (PCA)
Owners and operators of plants have been using thermoplastics for many years, transporting water, gas and chemicals along their process. However, for operational and maintenance purposes, the asset integrity of the piping system is required. This could be for a number of reason, such as piping system maintenance, ability to maintain current service conditions. EP offers its 30 plus years of plastic piping application experience to assess the fitness for service of used piping. Our specialists inspect the samples in our state-of-the-art accredited materials testing laboratory for piping components, to give our clients the necessary information to make an informed decision and next steps during a project’s operational, maintenance or design phases resolve threats to client assets. ExcelPlas offers the following testing to determine the condition of plastic pipes:
Technical Data:

  • Visual Inspection
  • Dimensional check
  • Oxidation Induction Time (OIT)
  • Melt Flow Rate (MFR)
  • Fourier-transform Infrared Spectroscopy (FTIR)
  • Hydrostatic Test
  • Differential Scanning Calorimetry test (DSC)
  • Vicat test
  • Microscopic analysis
  • Report with assessment of the integrity of the piping material

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.
