If we talk about plastics polyethylene (PE) is the best known and with a higher production. This proliferation has been thanks to its most advantageous properties, such as its flexibility, atoxicity, ease of installation, low maintenance in costs, resistance etc.
PE is used for different products, but we’re going to focus on pipes. When you want to join two polyethylene tubes it can be done primarily following two different welding procedures: electrofusion and butt welding. Both welds have fast execution, are very durable and are not too complex.
Before choosing what type of welding we are going to implant it is essential to make a pre-preparation of the surfaces on which the pipe joints must be carried out. In addition, we also have to take into account the work that we have in our hands. The last decisive factor is the oval process of the PE tube. These three aspects will determine what type of welding we should apply.
But now let’s know the advantages of each type of welding, although both are of quality and reliable.
On the one hand, we have the electrofusion. This type of welding is characterized by:
- It provides a lot of ease to access to the pipes that need to be welded when there is very little space.
- Compared to butt welding, electrofusion is lower priced and the weight of your equipment is lower, making your mobility easier.
- It provides a wide range of solutions with simple and in-load sockets.
- Electrofusion is highly recommended for individuals as the price of its installation is not very high and is more accessible to users.
On the other hand, there is butt welding. Its main advantages are:
- It allows you to remove the oxidized layer with ease, which is important before joining.
- It allows to weld different generations of polyethylene.
- It is possible to weld pipes with different generations of polyethylene.
- Self-cleaning of the weld after ejecting a portion of the material that has been melted.
- It’s a simple process why you don’t need any other add-on accessories.
- If the pipes that are solar have a diameter greater than 200 mm the butt welding is more efficient and economical.
- Simplicity in axial alignment and rounding of pipes.
- The PE tube makes it easy to curve without the rest of the installation increasing your tension.
