The original Electrofusion was invented & patented in 1977 by Swiss company Von Roll (manufacturer of Steel Municipal piping & Ski Lifts) The system was then called Rollmaplast. Many systems have developed since then with the basic initial concept of embedded resistance element in each socket and coupler is still being used today.

Advanced Piping Systems 39.5 Volt Electrofusion System has increased since our beginnings is 1990 to include the large sizes used in utility piping systems today.

Giant 1 Metre diameter couplers with dual heating zones meaning that situations that previously required a mechanical joint can now be accomplished with a socket to give the ultimate leak proof fully fused system.

The question often is asked should we buttweld or electro-fuse?

We can help you with this as both have their place and as the industry has matured there is an increasing numbers of projects that utilise both Buttwelding & Electrofusion welding on the same pipeline.
