COPPER CANCER IN PP-R HOT WATER PIPES (Breaking News)
Failed hot water PP-R systems with replacement values well over $200 million
https://www.linkedin.com/pulse/copper-cancer-ppr-hot-water-pipes-mark-alexander

“There’s not much point selling a pipe system in a plumbing market where there’s a fine line between failure and fit for purpose. PP-R is just not suited for hot water recirculated systems in Aus and NZ.”
James Boon , Technical Sales Consultant at UPG Pipe Systems
UPG Pipe Systems is one of New Zealand’s top suppliers of HDPE and PP-RCT pipe & fittings

Warning Over Substandard PEX Pipes
Some PEX pipe manufacturers use cost-cutting processes which lead to pipes that aren’t uniform in composition and are defective. Defective PEX pipes will not last 50+ years as advertised and quickly degrade and become brittle when exposed to hot chlorinated water. These pipes are destined to fail. Get your PEX pipes tested for Durability and Expected Service Life.
http://www.excelplas.com/

Warning Over Stresses on PEX Pipes
PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible oxidative degradation. This is especially true in some states where water chlorine levels run high.  PEX pipe that is bent beyond its limit can develop leaks at the stress points.

ExcelPlas Lab Specialising in HDPE Pipe Condition Monitoring, Failure Analysis and Testing
In the event of a HDPE buttweld or electrofusion weld failing during initial testing, or in service, we can conduct investigations to assist in identifying the root cause of the failure.
This service also extends to the premature failure of the pipe or fitting itself.

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.
