Electrofusion Welding

Electrofusion Welding

HDPE Pipes | HDPE Africa

Plain pipes are jointed by means of electrofusion (EF) fitting incorporating an electrical heating coil which when electrically activated for the appropriate time by electrofusion welding machine, melts the surface of the pipe & fitting together resulting in complete fusion of the pipe and electrofusion fitting. There is a barcode label on each of the EFfittings. This label includes fusion parameters (such as welding voltage and duration).

Fusion parameters are transferred to the machine from this label either manually or by using the barcode reader.
Advantages of EF Jointing Technic – there is no decrease in inner diameter of the pipe, low weight, low cost and flexibility of the equipment, high operation rates, fully automated operation, so need for skilled operator is at minimum level, no reduction in strength of material at jointed parts
