Extensive Failure Analysis of Plastic Pipes to Investigate a Wide Array of Possible Failure Scenarios
Polymeric pipe failures can happen at any time, and skilled insight is required to investigate polymer properties and characteristics which are measured in order to determine the cause of failure.   ExcelPlas determines root cause and solutions for polymer and plastic materials failure analysis, providing problem-solving and solutions for failure-related problems.  Our polymer pipe laboratories are staffed by scientists and technicians with significant expertise in multi-disciplinary failure investigation applications. Our includes experience with manufacturing faults, extrusion issues, stress, overload, oxidative degradation, unintentional service conditions, misuse and abuse.

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.

Importance of HLMI and Density Testing in the Manufacturing and Butt Fusion of HDPE Pipes
ExcelPlas has developed software to record and track high load melt index (HLMI) and density and their effects on butt fusion weld integrity. The software sets allowable ranges for HLMI and density for successful butt-fusion welding that overcomes the anticipated batch variability of PE100 polyethylene compounds.  The tracking of HLMI and density allows the ‘window’ of weldability to be determined by restricting essential polymer parameters such as melting, crystallization, and viscosity properties within limited ranges.

ExcelPlas Labs Determine Failure Mechanisms and Estimated Llifetime of Polymer Pipes
ExcelPlas specialise in Mode III failure of polymer pipes which is related to degradation and embrittlement of the plastic due to thermo-oxidation with time. Assuming Stage II failure is inhibited during service, due to correct design, installation and accurate qualification of material properties, it is Stage III which will ultimately determine the lifetime of a pipe material. Resistance to Stage III will be dependent on specialist additive packages added to polymer during manufacture to protect it from thermo-oxidative attack. Once these additives have been depleted, the onset of Stage III failure will commence rapidly.  PP-R, PEX and PB piping systems can experience premature oxidative (brittle) failures in potable water distribution systems.

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.

Assessing Remaining Service Life of Polyolefin Pipes (HDPE, PEX, PP-R, PB) (How Long Will My Pipes Last?)
ExcelPlas has developed Protocol for Determining the Remaining Service Life of In-Service HDPE Pipelines
The 5 step protocol is based on lab testing to measure the following:

  1. The oxidative induction time (OIT) profiling to assess whether or not oxidation protection is still afforded by the stabilising additives.
  2. Measure the carbonyl index (CI) to assess extent of any polymer oxidation that has occurred.
  3. Determine the critical CI at which oxidative stress cracking (OSC) is initiated.
  4. Measure oxidative stress cracking resistance (OSCR) to determine the time until OSC is initiated.
  5. Measure the depth of micro cracking on 180 degree bent coupons by Scanning Electron Microscopy
