Groundbreaking Research Links PVC and HDPE Microplastics to Increased Risk of Stroke and Heart Attacks
Microplastics and Nanoplastics in Atheromas and Cardiovascular Events
Researchers found that people with microplastics embedded in their blood vessels had a greater risk of heart attack, stroke, or death.
Doctors have warned of potentially life-threatening effects from plastic pollution after finding a substantially raised risk of stroke, heart attack and earlier death in people whose blood vessels were contaminated with microscopic plastics.  Those whose plaques contained microplastics or nanoplastics were nearly five times more likely to suffer a stroke, heart attack or death from any cause over the following 34 months, compared with those whose plaques were free from plastic contamination.

Transient response of hybrid and homogeneous pipelines: Laboratory experiments

To this end, transient tests were carried out on a high-density polyethylene (HDPE)+ cast iron (CI) hybrid pipeline at the Water Engineering Laboratory (WEL) of the University of Perugia, Italy. As a reference, tests were also carried out on a homogeneous HDPE pipeline with the same total length. The results of the laboratory tests showed that the value of the pressure local extremes (i.e., pressure peaks) was much higher in the homogeneous pipeline than in the hybrid one. On the contrary, the number of pressure peaks is much smaller in the homogeneous pipeline than in the hybrid one. Such features have been explained by analyzing the mechanisms of interaction of pressure waves at the in-series junction between the two different materials.

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.
