Today, the use of pipes and fittings made on the basis of polyethylene raw material has become very widespread. There are large industries that use this product on a large scale. Water transfer, gas transfer and many applications in petrochemicals. Meanwhile, products with unique features are used for gas transmission and distribution lines. For a long time, all over the world, developers are going for polyethylene instead of metal pipes.
What are the pipes and fittings of the gas polyethylene?
Raw materials in different grades and densities are used to make any product based on polyethylene material. The thickness of the pipes is also usually different. When these products are made with the specifications of polyethylene pipes, they are called gas polyethylene pipes. Considering that in the industry, the easy and safe way to connect these parts is to use electrofusion welding, gas polyethylene pipes and connections should be able to be welded in this way.
Polyethylene fittings
We know that most of the gas and fluid transmission route is through pipes. However, when we have to make deviations and detours due to the effects of the ground and the shape of the pipes, polyethylene joints should be used. In addition, connections are used to create branches for the main pipeline.
For example, consider a pipeline in a residential building. In order to enter a separate gas pipe to each unit, the plumber uses a connection called a tee. The presence of this part helps that each unit has its own branch without changing the main path of the pipe.
Electrofigen weld and polyethylene components
But in any project, do we need to connect separate parts? About metals, one of the easiest things to do is welding. Welding is done easily with electrodes. But polyethylene pipes are considered among plastics. These materials are not electrically conductive. In connecting different pieces of polyethylene, a secondary heat source should be provided. This heat source is used to create some melt at the ends of the two separated pieces.
Sometimes heaters are the heat source. These devices are familiar to many people. In building plumbing, we know them as solder. At the same time, the electrofusion method is used to generate heat and weld polyethylene gas pipes and joints.
