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.

Analysis of Residual Stress of Butt Fusion Joints for Polyethylene Gas Pipes
The performance of high-density polyethylene (PE) pipes joints directly affects the total pipeline’s operation, and so studying the residual stress of butt fusion joints is crucial for enhancing the safety of gas pipelines. Based on a layer-by-layer ring cutting test method, we measured the distribution of residual stresses in the fusion zone and heat-affected zone of butt fusion joints for PE gas pipes. 

Predicting Temperature Profiles in Soil and the Effect of Heat Conduction on Buried Thermoplastic Pipes During a Wildfire
The study was funded by Advanced Drainage Systems Inc. (ADS)
The method is used to generate a fragility curve, which shows the probability that the temperature on the exterior surface of a buried thermoplastic plastic pipe will exceed the maximum service temperature of 60°C as a function of soil cover thickness.

BREAKING NEWS

Fletcher Building (FBU) Eliminates Standalone Australian Division After Massive Losses
After last year’s losses, which have only widened in the company’s half year result in February, Fletcher took a closer look at the constituent parts of its business, seeking to possibly find buyers for parts of it. There were rumours at one point the company might seek to completely sell-off its Australian division, which investment bank Jarden had valued at $1.58 billion.  Troubled Iplex Australia is embroiled in a significant dispute over leaking polybutylene pipes, particularly in Western Australia. Iplex pipes installed in approximately 12,000 homes between 2017 and 2022 were found to be prone to leaks, leading to Fletcher having to put aside some $200m to cover potential payouts and remediations.

Damaged HDPE Pipes Blamed for Surge in Sewage Alerts and a £1.3m Repair Bill
Yorkshire Water said the alert system had been accidentally triggered due to two damaged outflow HDPE pipes and two damaged valves which had been letting in seawater.  The HDPE pipes had collapsed under load.

UK Water Authority Fined Record £1.42m for Drinking Water Failures
Anglian Water has been fined £1.4m for drinking water failures which affected around 1.3 million people.
The Drinking Water Inspectorate (DWI) said the company used unapproved plastic-based products to externally coat pipework submerged in drinking water tanks at four different sites.
The plastic coating did not meet leachate safety limits (e.g. for plasticizers, solvents, or degradation products), was not tested under Regulation 31 for WRAS/DWI approval, and failed to perform adequately under immersion conditions, releasing contaminants into the water.

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.

INDUSTRY ALERT – Release of Microplastics from PVC Pipes: An Accelerated Aging Study Using Ozonation, Chlorination and Heating
Microplastics (MPs) has been found in drinking water and aged plastic pipe could be an important source. In this study, the release of MPs from polyvinyl chloride (PVC) pipe after accelerated aging using ozonation, chlorination and heating was investigated. The release of MPs increased with the enhanced aging and the highest MPs release in 30 mg O3 L-1, 260 mg Cl2 L-1 and 80°C were 1058, 1256 and 1303 # L-1, respectively. The fractions of MPs with a size of 10-50 and > 50 µm increased with the increasing chlorine exposure, while the size distribution of MPs due to ozonation and heating tended to remain constant. The carbonyl index (CI) generally increased with the aging as a result of oxidation. Scanning electron microscope images showed that hole structures < 50 µm developed on the pipe surfaces especially under ozonation and chlorination. The results indicated that MPs < 50 µm could result from surface pitting and those > 50 µm were caused by surface peeling of the outmost layer of the pipe. This study provides essential insights connecting the concentration and size of MPs to surface morphology change after accelerated aging of PVC pipe.
