Plastic material pipes are very popular today. They are the most popular product category, which is characterized by a low price, proven quality and a wide variety. There are several specific features inherent only in plastic materials.
Pipes do not need to be painted and additionally covered.
Welding is not used for them.
Most of the plastic flexible.
The material has very small weight.
Thanks to this specificity, it is possible to create a wide variety of systems. Polymer pipes can be used for hot water supply, cold water supply, gas transfer, as well as for heating residential and commercial premises.
A feature of multi -layer pipes
Multilayer pipes are very popular today. They consist of several levels of material different in quality, which ensures their hardness. Due to the solid structure during installation, you need to use threaded fittings. They will allow you to change the configuration of the water supply as it needs to be done in a certain situation.
Multi -layer products can also be different. At the moment, their manufacturers use several technologies to ensure a strong connection of several layers. Consider the main technologies.
Glue
PP technology is the most common. The pipes created with it have three different layers. The first layer is the basis. It is a thick -walled polypropylene product. The material itself is quite soft and flexible. It is resistant to temperature extremes and large pits. But for more confidence, a second layer is applied over it – a layer of foil. Aluminum foil provides strength and is protected by the third outer layer of polypropylene.
Punching connection
If in the first case (according to PP technology) materials glued together, then the procedure is different here. In this case, they are connected using perforated holes. Since they cannot be performed in plasticity, the perforation is carried out on the foil. As a result, plastic pipes again consist of three layers: polymer, foil and polymer.
Modern alternative
The options are less common, where not foil is used as the middle layer, but a stronger layer of polymer material. It will no longer be polypropylene, polyvinyl chloride. However, despite such a seal, completely plastic products were not very popular.
