Butt fusion welding machine Georg Fischer Piping Systems

Butt Fusion Jointing

Butt fusion technology is the safe, reliable and favorable jointing for a wide dimension range.
GF Piping Systems offers mechanical, hydraulic and CNC-guided fusion machines for on site constructions and the workshop. The fusion areas of the pipes and fittings are heated to fusion temperature and joined by means of mechanical pressure, without using additional materials. A homogeneous joint results.

Socket Fusion Jointing
In this form of fusion jointing, which requires heating tools, the pipe end is inserted into the socket of the fitting; no additional material is used. The pipe end and fitting socket are heated to fusion temperature using a heating bush and a heating spigot, respectively, and are then pushed together.
GF Piping Systems offers a wide range of hand and mechanical guided fusion machines – also for the field-use. The pipe end, fitting socket and heating tools correspond in such a way that the necessary jointing pressure is attained during jointing, resulting in a

Electro Fusion Jointing
In the electro fusion process a heating wire permanently mouled into the fitting gets heated by current at a low voltage. The surrounding material around the wire gets melted and expands due to the warming. The melt starts closing the gap between pipe and fitting, leading to a heat transition to the pipe which also gets heated and melts in the welding zone. The pipe material also expands.
The increasing material expansion between pipe and fitting, which is hindered by the cold zones outside the welding zone, leads to a build up a welding pressure between pipe and fitting and a homogeneous welding connection emerges.
