Plasson PE Fittings will Increase by 4.5%

Research Project RP1-06 ‘Cracking in Polyethylene Pipelines’ which aims in creating greater insight into the polyethylene (PE) pipe degradation and lifespan is closed to finalisation.
The research has produced results addressing the deficiencies of using conventional test methods on aged pipes and distinguishing the best characterization techniques of long-term performance of PE pipes.

ExcelPlas Labs Undertake Failure Analysis, Failure Diagnosis and Root Cause Identification for Polyethylene Pipes
Failure in HDPE pipes could happen over a long term under low stress (under the yield stress).
The resistance to this phenomenon is the environmental stress-cracking resistance or slow crack resistance (SCR).
The high SCR in bimodal PE is due to the chain entanglements obtained with the incorporation of comonomers in the polymer of the high molecular weight fraction.
These entanglement networks affect the overall mechanical behavior under low stress conditions.
The failure includes several stages:
Microscopic cavities are formed around inhomogeneities such as scratches, pigments, catalyst residues, fillers and then these cavities form the initiation crazing step. It takes the largest fraction of the failure  mechanism. Once the deformation zone is formed, crazes propagate by the disentanglement of macromolecules and plastic deformation (yielding) until a crack initiation.

ExcelPlas Pipe Testing is a Leader in the Field of Polyethylene (PE) and High-Density Polyethylene (HDPE) Testing
ExcelPlas is accredited with the National Association of Testing Authorities (NATA) for butt weld tests, bend and tensile tests, peel decohesion tests on electro fusion sockets and failure mode determination

New UHMWPE Pipe for Tailing Offers Greater Than 4X the Abrasion Resistance of PE100

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.
