Assessing Remaining Service Life of HDPE Pipelines (How Long Will My Asset 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 stress cracking (SC) is initiated.
iV. Measure stress cracking resistance (SCR) to determine the time until SC is initiated.
V.  Measure the depth of micro cracking on 180 degree bent coupons by Scanning Electron Microscopy

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.
