New Realm of Possibilities for PEX Pipes [PEX]


Plastic Pipes Conference Association # 2006 Washington DC

Bar, Nitz

PEX (cross-linked Polyethylene) pipes have been traditionally used for indoor applications such as underfloor heating, hot and cold water pipelines and district heating pipelines. Recently these pipes are being used in mainly industrial applications, water mains and gas lines.

The success of PEX pipes in these and similar applications is based on the special qualities of the PEX material, some more known than others.

  • Excellent resistance to slow crack growth – SCG
  • Excellent longevity
  • Excellent abrasion resistance
  • Immunity to scratches and point loading

These last two issues will be discussed in this paper. I will also discuss a study we have conducted on PEX electrofusion couplers.
