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.
http://www.excelplas.com/

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.

Assessing Remaining Service Life of Polyolefin Pipes (HDPE, PEX, PP-R, PB) (How Long Will My Pipes Last?)
ExcelPlas has developed Protocol for Determining the Remaining Service Life of In-Service HDPE Pipelines
The 5 step protocol is based on lab testing to measure the following:
I.  The oxidative induction time (OIT) profiling to assess whether or not oxidation protection is still afforded by the additives.
II.  Measure the carbonyl index (CI) to assess extent of any polymer oxidation that has occurred.
III. Determine the critical CI at which oxidative stress cracking (OSC) is initiated.
iV. Measure oxidative stress cracking resistance (OSCR) to determine the time until OSC is initiated.
V.  Measure the depth of micro cracking on 180 degree bent coupons by Scanning Electron Microscopy

Assessing Remaining Service Life of Polyolefin Pipes (HDPE, PEX, PP-R, PB) (How Long Will My Pipes Last?)
ExcelPlas has developed Protocol for Determining the Remaining Service Life of In-Service HDPE Pipelines
The 5 step protocol is based on lab testing to measure the following:
I.  The oxidative induction time (OIT) profiling to assess whether or not oxidation protection is still afforded by the additives.
II.  Measure the carbonyl index (CI) to assess extent of any polymer oxidation that has occurred.
III. Determine the critical CI at which oxidative stress cracking (OSC) is initiated.
iV. Measure oxidative stress cracking resistance (OSCR) to determine the time until OSC is initiated.
V.  Measure the depth of micro cracking on 180 degree bent coupons by Scanning Electron Microscopy

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.

Chlorinated PVC Piping Versus PEX Piping
There have been at least 22 plumbing failure class action lawsuits in the last 17 years and since 2008, 10 have involved PEX plumbing systems, stemming from failures due to contact with the drinking water.
Studies have shown that PEX piping can leach substances, including gasoline components such as MTBE, ETBE, TBA and Toluene.
