Aquatherm Sued by USA Over ‘Defective’ PP-R Pipes (July, 2022)
UNITED STATES OF AMERICA, Plaintiff, v. AQUATHERM GmbH; AQUATHERM L.P.
Plaintiff asserts claims of breach of express warranty, breach of implied warranty of merchantability, breach of implied warranty of fitness for a particular purpose, and unjust enrichment
As alleged in Plaintiff’s Complaint, the United States seeks to recover the cost of replacing defective pipes in a federal building in Portland, Oregon. Between 2009 and 2013, the General Services Administration (GSA) renovated the Edith Green-Wendell Wyatt Federal Building (the Building). The first of several pipe leaks occurred in March 2018. Since then, the AQ GmbH PP-R pipes allegedly failed another eight times, and Plaintiff contends that they will likely continue to fail because they are defective and unsuitable both for ordinary use and specifically for use in the Building.

Property Owner Sues Insurance Company Over Defective Polybutylene Pipes (2022)
Polybutylene pipes are well known throughout the insurance industry as being uninsurable and usually excluded from coverage.
On or about December 31, 2018, Vasquez’s polybutylene plumbing system ruptured causing water damage to Vasquez’s residence. At the time, Vasquez was insured by Ameriprise under policy number HI01975533 (“the Policy”) which covered Vasquez’s residence. After learning that the pipes were considered defective and could cause more problems at a later time, Vasquez decided to replace the entire plumbing system, including portions that were not leaking.

HDPE PIPE JOINT FAILURE EXPERTS
The failure of electrofusion or butt fusion joints in polyethylene gas pipework can be due to several factors including incorrect alignment, contamination, incorrect temperature or the duration of joint fusion.
If a joint failure occurs, investigations are important to help identify modifications to procedures or training that can help you minimise the occurrence of future failure. This is where we can help.
We provide a detailed PE joint failure investigation service which typically include:
- Digital inspection of the received sample, including dimension measurements of sizes and ovality
- Segmenting the joint for visual and microscopic investigation
- Elemental analysis of any contamination found in the joint
- Peel decohesion testing

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.
