Cautionary Warning:  Some PEX Piping is Prone to Development of Cracks Due to Early Oxidation
ExcelPlas Labs have developed a three-step testing program to detect early failure of PEX pipe and their expected service lifetime.
The 3 Step Testing is based on:

  • Oxidative Induction Time (OIT) testing to determine the residual level of oxidative stability (i.e. thermal stability)
  • Quantitative Additive Analysis (QAA) to determine the type and level of protective antioxidants and stabilizer present.
  • Scanning Microscopy on inner surface after bend back to image developing microcracks

Samples of PEX pipe just 10 cm long are needed for the analysis.  7 Day turnaround on test reports.

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.

PLASTIC PIPE FAILURE ANALYSIS

Failure Analysis of Plastic Pipes
If you are looking for an expert witness for your case involving plastic pipe failure analysis, then you can’t beat the team at ExcelPlas Consulting.  Our team is setting a new standard for excellence in failure analysis of plastic articles but especially plastic pipe.  For plastic pipe, this includes HDPE, PVC & CPVC pipe as well as other plastic piping systems like Hobas GRP pipe, PP-R Pipe, and spoolable composite pipe.  When a plastic pipeline fails to perform as intended, our team can determine the root cause (chemical failure, oxidative failure, creep failure, overstress failure, fatigue failure, design failure, etc).   We are experts in HDPE water pipe failures, CPVC sprinkler pipe failure, PVC pipe failure analysis and PP-R Oxidation/Degradation investigations.

Cautionary Warning:  Some PEX Piping is Prone to Development of Cracks Due to Early Oxidation
ExcelPlas Labs have developed a three-step testing program to detect the early failure of PEX pipes and their expected service lifetime.
The 3 Step Testing is based on:

  • Oxidative Induction Time (OIT) testing to determine the residual level of oxidative stability (i.e. thermal stability)
  • Quantitative Additive Analysis (QAA) to determine the type and level of protective antioxidants and stabilizers present.
  • Scanning Microscopy on the inner surface after bend back to image developing microcracks

Samples of PEX pipe just 10 cm long are needed for the analysis.  7 Day turnaround on test reports.

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.
http://www.excelplas.com/

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 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.
