PIPA has Revised and Republished Two Guidelines, POP004A and POP016

POP004A “Supplementary list – Materials Specific to Electrofusion and Moulded Fittings” has been updated (Issue 1.9) with the latest AS/NZS 4020 certification of Ineos’ injection moulding PE100 grades, ELTEX TUB121 and ELTEX TUB121 N6000.

POP016 “High Stress Crack Resistant PE100” has been revised (Issue 1.2) to reflect the Polyolefin Technical Committee’s acceptance of an alternate accelerated form of the EN 12814-3:2014, 2-Notch Creep Test. The accelerated 2NCT+ test’s correlated time to failure is >195hrs; 90°C; 4N/mm2 tensile stress; 2% NM5 surfactant.

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.
