PE (polyethylene) pipes are currently the basis for a solid and efficiently operating water supply system. Their simple and effective connection, also in the case of complex systems, is ensured by various types of electrofusion fittings. Electrofusion joints occupy an important place among them. Get to know the most important advantages of using this type of fittings and learn how electrofusion welding of PE pipes using joints is carried out.

Advantages of using electrofusion joints
The electrofusion coupler enables easy and solid connection of two parts of the installation. Thanks to being made of polyethylene (PE), this element is characterized by excellent durability. Polyethylene is a material highly resistant to mechanical and chemical damage and low temperatures, and at the same time thermoplastic.
The PE joint can work in aggressive environments where pipelines are exposed to acids, alkalis, salts, frost, etc. Thermoplasticity allows the element to be welded. A wide range of available dimensions and diameters of joints facilitates the implementation of the most complex and unusual water networks. The system made of PE pipes and fittings is characterized by durability, tightness, plasticity and a high level of hygiene. It is important that the muffs selected for the project ensure even heat distribution.
Electrofusion welding of pipes with sleeves
Electrofusion welding is a simple and, consequently, very popular method of connecting PE pipes. To make durable connections and minimize the risk of installation failure, the electrofusion welding process requires the use of special shapes and special environmental conditions. The temperature at the welding point is important and should range from -5oC to 45oC. When using a welding machine in a workshop, this condition is usually met. However, it must be remembered that welding work often has to be carried out in the field in unfavorable weather conditions. The protective tent is then unfolded and a blower is used to heat the air.
The electrofusion sleeve has heating elements that allow you to connect one pipe to another. To make a connection in this way, you need an electrofusion welder placed on a stable surface (do not place the tool on the ground!). The work should begin with proper preparation of the pipes. They must be thoroughly cleaned, dried and cut appropriately. Cutting is done at a right angle, i.e. perpendicular to the axis of the elements. The next step is to remove the layer of oxidized polyethylene to a maximum thickness. 0.2mm. For this purpose, it is worth using a manual stripper and a special degreasing wipe. Finally, fix the pipes and joints with clamps. This will prevent the elements from moving. Ready? You can start the actual electrofusion welding.
The main function of welders is to transmit voltage to the fittings, which - due to the melting of polymers - connect to the pipes. An automated, practical, maintenance-free device helps you perform the weld correctly. Setting the right parameters for the process increasingly comes down to scanning a unique barcode using the scanner attached to the welding machine. Code and other information, including: diameter, type and welding and cooling time can be found on the label attached to the fitting. A message about the end of work will appear on the device's display. Then disconnect the cables.
