Electrofusion of thermo pipe

Electrofusion is a method of joining 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 and a voltage is applied for a fixed time depending on the fitting in use. It’s of high importance that the material i clean and dry. 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 OPD skilled welding staff have long experience from various electro fusion assignments.
