Aquatherm Appealing King County Decision on Defective PP-R Pipes
The King County lawsuit alleged defective PP-R pipe, improper manufacturing controls of the PP-R pipe, failure to warn of installation vulnerabilities, misrepresentations about expected durability of PP-R pipe and warranty breaches.
United States Government sued Aquatherm GmbH for defective pipe installations in a federal building, alleging breach of express and implied warranties.
A Jury verdict of USD $18 million was found against Aquatherm entities. The trial judge also imposed ≈$1.5 million sanctions on Aquatherm for discovery violations.
Washington State Court of Appeals has published update relating to King County v. Aquatherm GmbH (and affiliated U.S. entities)
That decision held the federal court had personal jurisdiction under Rule 4(k)(2) over Aquatherm GmbH, even though that company did not have state-by-state contacts, because it had U.S.-wide contacts.

New Experimental Approach to Chemical Ageing in Plastic Piping for Drinking Water Infrastructure Exposed to Chlorine Dioxide
The long-term durability of polyethylene (PE) pipes in water distribution networks is gaining importance due to updated European regulations on drinking water safety. This study investigates the accelerated ageing of two PE grades (PE1 and PE2) exposed to chlorine dioxide (ClO₂), a disinfectant known for its high efficacy and minimal formation of harmful by-products.
Based on degradation kinetics, the estimated service life under real operating conditions was 18 years for PE1 and 23 years for PE2 at 40°C.
A Carbon Footprint Analysis of Drinking Water Pipes in Tokyo
This study quantifies the carbon footprint of the drinking water service pipes connecting distribution pipes to households in Tokyo, which transitioned almost entirely to stainless steel by 2004
By 2004 nearly all potable water service pipes in Tokyo had been replaced by Type 316 stainless steel and leakage rates had fallen significantly

Detecting Types of Impurities in Weld Joints of Outdoor Polyethylene Pipelines
This work used a large dataset of PE pipe joint samples created in harsh outdoor environments, in contrast to past studies that mainly used datasets created under controlled and laboratory conditions. The results show that the accuracy of the impurity recognition rate of this model is 86.29%, and that the automation process allows the identification of quality defects faster than the manual inspection method.
Exploration of Data Interpretation Methods and Machine Learning–Based Failure Prediction Models for Plastic Gas Distribution Pipelines
Additionally, leaks caused by pipe or welding material degradation are more common in older plastic pipes. The study introduces a predictive model that can forecast failure modes in plastic pipelines with 72% accuracy.

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.
