A New Generation of Electrofusion : A technical comparison between the new wedge coupler and the traditional cylindrical coupler for PE pipes d1000 (40”) and above. FRIATEC has developed a totally new concept of electrofusion jointing method for large bore PE pipes, d1000 mm (40”) and above. The new method completely revolts existing practice with respect to easy installation, fast progress and minimal energy consumption. Compared with standard EF fittings in large dimensions the new technique allows a dramatically reduction in processing time, eases installation and does not require additional devices on site. Basic design criterion of the fittings is maximum reliability in processing of the joint under rough site conditions as well as durable operation of the pipe system. The presentation introduces the new concept, shows the advantages of the new method and highlights processing with respect to practical and economical aspects.
