Mobile HDPE Pipe Extrusion Technology Company Prepares for IPO
https://privatecompanyplatform.com/company/?polyline-pipe-systems-ltd

Polyline Pipe Systems Offers Unique Technology – Truly Mobile HDPE Pipe Extrusion

  • Continuous pipelines substantially reduce welding requirements and associated costs.
  • Reduced truck/container movements and transport costs to site.
  • Reduced requirements for site lay-down and storage areas for pipe lengths and pre-installation equipment
  • Reduced welds minimises potential failure points
  • Reduced internal welding seams = less turbulence, better flow, and less wear = longer pipeline life

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 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.

Plastic Pipes are Polluting Drinking Water Systems After Wildfires – it’s a Risk in Urban Fires, Too (Breaking News)
Results indicated that thermally damaged drinking water pipes can be sources of VOC leaching, with ten of the eleven materials (namely PEX, HDPE, PP, PVC, and CPVC plastic drinking water pipes)  leaching benzene, a carcinogen, into water without the end user knowing.  This study has significant implications for both wildfire and structure fire recovery as plastic materials are increasingly being used in buried and building plumbing, and visual inspection is not a sufficient indicator of contamination risk.

Borouge Researchers Study on the Re-distribution of Residual Stress in Polymer Pipe Extrusion and Effect of Eccentricity on Pipe Failure Time
Residual stress in pipes induces compressive force at outer surface and tensile force at the inner surface of the pipe. The compressive stress near the outer surface can help suppress failures initiated by external cracks near the external surface. On the other hand, the tensile stress near the inner surface of the pipe adds to the stress generated by hydrostatic pressure thus it increases the net stress the pipe is exposed during a hydrostatic pressure test, hence reduces the time to failure.

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.

FAILURE ANALYSIS

Analysing Causes of Poly Pipe Failure
If you want to assess the current condition and the residual estimate lifetime of polymer pipes, one key element is to know the important factors contributing to the failure – and how do those factors play out in the real world.  Identifying risk factors for pipe failure such as temperature, cyclic pressure, copper ions, chlorine, free-radicals and other impact factors.
ExcelPlas polymer researchers investigate the most common factors in polymer pipe failure and cracking.
