Drinking Water Contamination From the Thermal Degradation of Plastics: Implications for Wildfire and Structure Fire Response [PDF]
Purdue Researchers Show Plastic Pipes Are Polluting Drinking Water Systems After Wildfires (Breaking News)
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.

PE PIPE FAILURE
British Plastics Federation (BPF) Publishes Failure Modes of Polyethylene Pipelines Under Pressure
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.
PVC PIPE FAIURE
Failure Modes of PVC Pipes: Burst Failure of PVC Pipes, Long-Term Pressure Failure of PVC Pipes, Cyclic Surge Failure of PVC Pipes
Exposure to POE Oil Can Be Disastrous to PVC Piping
POE oil is a synthetic oil that is used to lubricate compressors utilized in direct expansion (DX) systems utilizing refrigerants such as R410A. POE oil is added into the R410 refrigerant charge, and it circulates with the refrigerant. Substance can lead to environmental stress cracking of PVC and CPVC pipes.

ExcelPlas Investigating Poly Pipe Failures
Through failure analysis & forensic chemistry, we help clients improve product performance, increase profits, & resolve product liability claims with plastic pipes and fittings.
We are dedicated to unmatched excellence in failure analysis, investigative chemistry, material testing, and expert witnessing for plastics, polymers and composites.
With over 25 years of investigative experience, the staff at ExcelPlas are uniquely positioned to help clients resolve the most challenging performance and processing issues related to materials and finished pipes and fittings.
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.
