Polyethylene networks have been widely used in the world for many years, and today, like GAZ de FRANCE, many gas companies use electrofusion techniques for assembly of pipelines. Recent developments in the polyethylene technique are described, in particular the simplification of installation procedures and the operation of pipelines in service. The first point involved the design of high performance tools, independent of equipment brands, easily operated under work-site conditions: for example, automatic welding units able to adjust electrical parameters without any intervention by the operator. The second point concerns not only tools, but also the processes used both to solve problems linked to large diameter pipes and to extend the possibilities of the polyethylene technique. These different applications illustrate the latest developments in electrofusion, fittings, tools and installation methods which guarantee a polyethylene technique of high quality.
