In the early days of polyethylene piping use, there was no forum, such as the Plastics Pipe Conference, where information could be disseminated and technical experience exchanged. Thus, each piping community, whether a pipe manufacturer, gas or water company, or technical body, developed their own philosophies and procedures for welding of polyethylene piping. As a result, there has long been disagreement in the international community concerning the parameters used to fuse this increasingly used material. This paper will look at the differences between the two primary fusion parameters, high fusion interfacial pressure and low fusion interfacial pressure and examine the most beneficial aspect, increased productivity without sacrificing quality.

This author presented the thought provoking paper “Butt Fusion Cooling Times, Speeding Up the Process” at Plastic Pipes XV held in Vancouver, British Columbia, Canada.. That presentation discussed testing of heavy walled pipe using various fusion standards and the resulting cooling times with relative joint strength....

The polyethylene (PE) pipe system has many attributes that make it the most reliable and highest quality system within the prescribed pressure and temperature limitations. However, the process itself is the weakest link in the PE pipe sales chain. While easier to join in large diameters, it can require the most time...
