Electrofusion Coupler

Electrofusion coupler is used as an additional part by bringing together pipe parts from liquid and gas underground lines. It reveals an active boiling process due to the copper wires inside. As the raw material in its production, PE 100 material has added value compared to its competitors against its extreme resistance against long-lasting corrosion. Since PE100 and HDPE do not distort their elastic shape even at -40 degrees, they are used more especially in cold climates.

It is an attachment that is produced by the combination of polyethene or raw materials, and according to the diameter of the pipe produced by turning or injection technique, copper, brass, nickel alloy wires are wrapped. This determines the endurance strength of the wire sleeves that are wrapped in them, and the welding time, welding voltage and cooling time are determined by considering the melting temperature of the polyethene.

The duration of the welding voltage can be provided differently from manufacturer to manufacturer. The manufacturer creates these standards with 24 characters and sticks them on this attachment with a barcode, and these standards are created by obtaining positive results from the necessary tests in the rooms of the production providers with air conditioning and conditions.

HDPE Electrofusion Coupling

HDPE pipelines electrofusion coupling application booklet manufacturers specified in the catalogues. According to DVS 2207-1 or according to different welding standards. By using electrofusion welding machines, the welding process of the sleeve and electrofusion elbow and other additional parts are completed.

HDPE Electrofusion Coupler

The joining process is done using HDPE electrofusion sleeve electrofusion welding machine produced according to PrEN 12201-3. The most important point in sleeve production is to place the wires with determining electrical conductivity. The coupler must be done precisely by highly high-tech machines.


Electrofusion makes the conductive wires heat by giving an electric current. In this way, the required area is melted by heating the material to its melting temperature. When the melted material cannot find an area to flow, it expands and creates the pressure force required for welding between the 2 regions. By this way the pressure and temperature parameters required for welding are provided.
