Comparison of Long-Term and Short-Term Tests for Electrofusion Joints in PE Pipes [PE]

# 2006 Washington DC

As part of the Polytec Systems European-funded project, electrofusion (EF) joints in polyethylene (PE) pipe, containing different flaws, have been subjected to various standard and non-standard, long-term and short-term, coupon and whole pipe tests. The results were compared to determine which tests could discriminate between standard welds containing no deliberate flaws and welds containing different types and degrees of flaw (including particulate contamination, unscraped pipe surfaces and cold welds), and whether any shortterm tests provided data that could give an indication of long-term performance.

The S4 critical temperature (CT) for 110 mm pipe was correlated with the plane stress impact energy for 13 resins. A plane stress impact (PSI) test is offered as an inexpensive way to control RCP by determining the lot to lot variations of the critical temperature of a resin. Details of the PSI test are presented.
