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.
