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 at ExcelPlas Labs.

Rehau Expands PEX for Municipal Water & Wastewater Line
Rehau is offering two additional cross-linked polyethylene PEXa pipes in their municipal piping program. In addition to Municipex water service line, the expanded product range now includes Municipex pre-insulated for cold-weather applications and Municipex force main for wastewater applications.  “With more than 1 billion ft of Rehau PEXa pipe installed worldwide and many North American water service projects, municipalities have reason to trust Municipex to safely and efficiently transport potable water” said Dale Gentry, Rehau Municipex national account manager. “Now, with our expanded line including pre-insulated and force main, we are building on this proven performance with cold-weather and wastewater solutions. These products offer the efficient installation and longevity that municipalities have come to expect from Municipex water service line.”

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 Pipe Testing is a Leader in the Field of Polyethylene (PE) and High-Density Polyethylene (HDPE) Testing
ExcelPlas is accredited with the National Association of Testing Authorities (NATA) for butt weld tests, bend and tensile tests, peel decohesion tests on electro fusion sockets and failure mode determination

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.
