Ductile Saves the Day When HDPE Fails after 5 Years
“Polyolefin materials such as Polyethylene (HDPE) are inherently susceptible to oxidation by chlorine-based water disinfectants*.  This will drastically shorten the lifespan of HDPE causing premature failures and splits. “

Wear Resistant UHMWPE Pipes to Pump Dredged Spoil, Such as Sand, Sludge, Sediment, etc. 
The UHMWPE pressure pipeline can be installed on land as well as on water. On water, the pipelines can be equipped with float collars.
We have HDPE pressure pipes with dimensions from 100 mm to 250 mm. The dredging hoses are equipped with steel flanges at the end. A slurry pipecan be used for easy connecting and disconnecting of the pipelines. The pontoon is equipped with a Davit crane with winch.

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.
