A deep understanding of the gap closing process during electrofusion is necessary to design electrofusion fittings (esp. couplers), which give best assumptions for good fusions on site. In one respect, measurements of temperature, melt-pressure and change of circumference during electrofusion and on the other hand simulation methods like finite element method (FEM) are important tools. These tools can be used to analyse and to optimize fusion conditions and product performance. One result of this work is for example a specific pitch for the heating element to get better joint quality at the end of the heating coils of the new ELGEF Plus couplers.
