PIPA Updates POP004 on POLYETHYLENE PIPE AND FITTINGS COMPOUNDS
https://www.pipa.com.au/wp-content/uploads/2019/09/POP004.pdf

American Gas Association (AGA) petitioned the Pipeline and Hazardous Materials Safety Administration (PHMSA) to reconsider language regarding heat fusion procedures provided in the plastic pipe rule. Specifically, AGA asks PHMSA to broaden § 192.281 of the pipeline safety regulations to allow qualified heat fusion procedures outside of, but in accordance with, ASTM F2620-12 Standard Practice for Heat Fusion Joining of Polyethylene Pipe and Fittings.

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.
