Electrofusion 

Electrofusion is a method of joining MDPE, HDPE and other plastic pipes using special fittings that have built-in electric heating elements which are used to weld the joint together.

The pipes to be joined are cleaned, inserted into the electrofusion fitting (with a temporary clamp if required) and a voltage (typically 40V) is applied for a fixed time depending on the fitting in use. The built in heater coils then melt the inside of the fitting and the outside of the pipe wall, which weld together producing a very strong homogeneous joint. The assembly is then left to cool for a specified time. The joints produced tend to be more reliable than threaded fittings sealed with O-rings.

 

 Tapping Saddle

Polyethylene Tapping Saddles saddles are used to create branches within the PE pipeline systems when connecting smaller sizes into bigger size mains. They are available in PE100 SDR11 PN16.

 

There are a number of different brands available of branching saddles and they either come complete with an under part or with out. An under part provides for support of the saddle when they are being electrofused into place.

All fittings are manufactured to comply with a number of international standards. These include ISO 4427, ISO 8085, EN 1555, EN 12201, AS/NZS 4129:2008, AFNOR NF 136
