More recently, the use of plastic pipes for sewage, water supply or heating was considered a novelty, but today they have found widespread use. Polyethylene pipes, the technical characteristics of which greatly distinguish them from metal ones, sometimes serve their masters even more than 50 years. So what is their feature?
Overview of polyethylene pipes
The first and main advantage of such a pipe is its resistance to corrosion. It is thanks to her that they can withstand a sufficiently long period of time without repair. In addition, polyethylene pipes for plumbing and sewage are not subject to electrochemical corrosion. Their inner part is smooth, which can significantly increase throughput. Even after many years of operation, polyethylene pipes for water supply, heating or sewage have a much better pass than metal pipes, due to the fact that no deposits remain on their walls. Shaped parts can be created not only from plastic, but also from metal. In addition, condensation cannot form on their surface. These advantages made polyethylene pipes (their technical characteristics will be described below) so popular.
Characteristics of polyethylene pipes
If we consider polyethylene pipes (technical specifications), sewer, plumbing or heating, then first you need to pay attention to the brand of material that is used in their composition, then we will talk about indicators of pipe resistance to pressure from the inside and about the diameter of the product. That is why, if you want to learn more about what polyethylene pipes are, their technical characteristics and features, you should first familiarize yourself with what types of polyethylene are:
- PE 63 (not applicable today).
- PE 80 - has good properties and can withstand a fairly high pressure of any liquids. This brand is used in the creation of pipes of small diameter, which are laid for water supply.
- PE 100 - is used to create pipes with a large diameter, which are used in the construction of pipelines with cold water supply.
The diameter, which is also included in the characteristics of polyethylene pipes, can be completely different. The range is from 20 mm to 120 cm. Their length largely depends on what their diameter is. So, for example, a pipe diameter of 20 to 110 mm assumes that its length does not exceed 50 meters.
The advantages of large diameter polyethylene pipes
Recently, it is pipes with a large diameter that are in greatest demand. This can be explained by the fact that they are used for the construction of pressure head water supply, drainage system, storm sewer or sewer. They have several important advantages over metal models:
- Production, installation and operation are cheaper than in the case of metal.
- If the water inside freezes, then nothing bad will happen.
- The weight of the pipe is much lower, therefore transportation and installation are easier.
- Technical polyethylene pipe is safe and non-toxic.
- There is no need to worry during transportation, as they are not dangerous goods.
- Resistant to bumps and sprains. The joints are more reliable and durable, which increases the life of the pipe.
Polyethylene sewer pipes
Thanks to polyethylene, the sewage system has acquired a new look, and its quality has significantly improved. The fact is that polyethylene helps to improve the development of the system itself, and its construction is many times easier and faster. For example, you can use the so-called trenchless laying. Polyethylene pipes, the technical characteristics of which help them not to be influenced even by strong chemicals, can be easily transported and mounted. Their connection is considered more durable and reliable, which helps protect against accidents.
Corrugated polyethylene pipes
This type of pipe for sewers and water supply systems is made of special two-layer polyethylene. Typically, they use the brand PE 80, which in diameter is most suitable for this model. Pipes are resistant to chemicals. Due to the special ring stiffness, which is quite high, corrugated polyethylene pipes can be mounted using a hidden method at a depth of one to twenty meters. There are corrugated pipes made of polyethylene and for the so-called external sewage drains.
Pressure pipes for sewers and water supply
Polyethylene grade 80 is the most durable of all known to date. That is why it is used to create special polyethylene pipes that withstand both high and low pressure. They can be used without problems even in a very aggressive environment, but the main area of application is still water supply. For sewers, they are not suitable. Today's most popular diameter of such pipes is from 2 to 6.3 cm.
Well-known manufacturers of polyethylene pipes
In construction stores today, from a huge variety and assortment of polyethylene pipes, eyes simply run up. If you do not know which pipes are best to purchase, you should first find out who produces these models.
The most popular company for the production of polyethylene pipes for sewers and water supply today is Rehau. It creates high-quality and sufficiently durable products that are suitable for water supply and sewage systems of any complexity and length. In addition, the polyethylene water pipe, the technical characteristics of which indicate its high quality, is distinguished by its ease of assembly, ease of transportation and ease of the system itself.
Wavin from the Netherlands produces polyethylene pipes for sewers. Choosing this company, you will forget for a long time what repair is. The main feature of Wavin polyethylene pipes is that they have high soundproofing properties and also withstand high temperatures (up to 90 degrees).
Russian manufacturers also do not lag behind foreign ones and produce pipes made of high-quality polyethylene of the so-called low pressure. Such models have a lower cost, therefore, are quite popular among builders and buyers.
