Fundamental Aspects for Design of Electrofusion Fittings - 1995 [PE]

 

Plastic Pipes Conference Association # 1995 Edinburgh

Hilger, Petry, Barbari

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.

Electrofusion (EF) sockets constitute a well-established and practically proven technology for the joining of polyethylene (PE) pressure pipes. As for the pipes, the potential lifetime of such welding connections is beside other properties also depending on the resistance against slow crack growth (SCG). The current...

Electrofusion is undoubtedly the most important method for jointing polyethylene piping systems in gas and water distribution. Today it is not unusual to joint PE 100 pipes and fittings in diameters up to 500 mm using electrofusion couplers whereas only five years ago the maximum size used was 315 mm. With these...

Quality assurance (QA) systems according to IS0 9000 series are no longer the "privilege" of the suppliers to the plastic piping systems market. Also the endusers, in this case mainly gas distribution companies, are under-taking efforts to set up QA-Systems according to IS0 9000 series. Doing this more emphasis was...
