Electrofusion method joins polyethylene pipe and fittings
The electrofusion method of joining polyethylene pipe was developed in Germany for use in non-pressure applications. It is now being used by British Gas, Gaz de France and German gas companies and U.S. distributors for the installation of polyethylene gas distribution systems. Electrofusion is considered the solution to field problems currently encountered, such as consistent sidewall fusion, repair problems and excavation costs, especially in large diameter mains, and the different times and temperatures required for joining dissimilar polyethylene materials. The electrofusion process eliminates some of the problems of improper iron temperature, misaligned fittings, dissimilar pipe materials, fusion of large diameter pipe and stress crack failures of socket fittings.
