Pipes for outdoor sewage - the rules of choice
Sewer pipes for external sewage are the most important elements of the liquid waste transportation system. From what type of similar products was chosen for communication installation, its service life and reliability directly depend.
In order to understand which materials are best suited for creating an external sewer pipeline, it is necessary to get acquainted with the characteristics of each of them.

When installing external waste systems, a very important point is the selection of materials.
For laying in outdoor conditions suitable materials that will be endowed with the following characteristics:
- High strength performance;
- Wear resistance;
- Resistance to aggressive environment;
- The ability to tolerate temperature drops, while not cracking and deforming.
In today's market, consumers can meet with the widest range of materials for outdoor pipeline installation.
Among all this diversity, the following are considered the most popular:
- Cast iron;
- Plastic;
- Ceramic;
- Asbestos cement.
Note! The durability and efficiency of sewage depends not only on the quality of materials, but also on the correct installation.
Asbestos cement materials

These types of pipes are made from mortar made from Portland cement and asbestos fiber.
The advantages of this type of pipe include:
- Low weight;
- Smoothness that persists for long;
- Durability;
- High throughput.
The only, but rather important disadvantage of such pipes is fragility, which makes it necessary to protect them from mechanical effects.
Installation of this type of pipeline in the street is not difficult, because the pipes are easy to process. They can be cut without the use of specialized tools.
Council Instructions for the purchase of products from asbestos cement requires the need to carefully inspect the ends. It is in these parts of the product that chips often appear due to inaccurate loading and transportation.
Plastic pipes

In modern construction materials from cast iron, ceramics and even asbestos cement can be found extremely rarely. Today's developers give their preference to plastic products for arranging the street part of the pipeline.
This choice is due to the many advantages of plastic:
- Availability due to the fact that the price is low;
- Easy installation due to the lack of need to use specialized equipment for installation;
- Durability. With proper installation, the system will last at least 50 years.
Pipes that are suitable for installation of the outdoor part of the pipeline can be made of different types of polymers. Consider some of the most popular options.
PVC - polyvinyl chloride
![The components of the sewer system The components of the sewer system](../uploads/img/sostavlyayuschie-kanalizatsionnoy-sistemy.jpg)
Such a variety is now widely used not only to create a new sewage drainage system, but also to carry out repair work as a replacement for worn-out areas. PVC sewer pipes for external sewage can be used to transport not only domestic waste, but also for removal of industrial and rain drains, the temperature of which does not exceed 60 degrees.
Note! Installation of PVC systems with their own hands is produced by the socket method, in which the tightness of the connection of elements is ensured through the use of rubber cuffs.
The advantages of PVC include:
- Resistance to freezing temperatures. They are not subject to cracking even when completely freezing;
- Low weight, which allows for the installation of products without the use of specialized tools and lifting equipment;
- Completely immune to corrosion processes;
- Resistance to accumulation of precipitation on the inner walls of the sewer main;
- Wear resistance even in terms of sand transportation.
According to this parameter, as the rigidity of the product from polyvinyl chloride, they are divided into two classes:
- Class N - load 8 kN.m2;
- Class S - load 4 kN / m2.
In addition, PVC sewer external pipes are divided into 3 types:
- Light - designed for laying systems in places where there is no transport load;
- Medium - for installation in areas with low traffic load;
- Heavy - for stacking under highways and in industrial areas.
Polypropylene

Such products are most widely used when laying the outer sections of the wastewater transport system. This type is usually recommended for the organization of sewer free-flow type and for the installation of networks of a residential house.
Advantages of polypropylene:
- Low mass;
- Elasticity;
- The smoothness of the inner diameter;
- Resistance to aggressive environmental influences.
Polyethylene

Polyethylene pipes are often used for the installation of external drainage network.
This type has many advantages:
- Ease of installation work;
- Long service life;
- Resistance to subzero temperature and sudden temperature changes.
Corrugated products
![Corrugated double-layer pipes Corrugated double-layer pipes](../uploads/img/gofrirovannye-dvuhsloynye-truby-405x450.jpg)
In order to make the pipe much more durable, they are made of corrugated two-layer. In the manufacturing process used PVC or low pressure polyethylene.
Such corrugated material has the following features:
- Increased stiffness rates;
- The connection of parts is carried out by cold welding or with the help of rubber cuffs;
- Open and closed laying options are allowed;
- The flexibility of the product allows you to bend it without additional processing and accessories.
Corrugated materials are made of two main layers:
- The inner layer is smooth allowing the drains to pass unhindered;
- The outer layer is a hard layer of corrugated material that provides resistance to external influences.
The disadvantages include a low melting point, which means that they should not be purchased for the installation of hot water systems or heating. In addition, one of them is not worth building a fire water system, because This system works under pressure.
Additional parts for assembly

For the installation of the sewer pipeline will require not only pipes, but also elements such as:
- Couplings;
- Plugs;
- Tees;
- Check valves;
- Transitions;
- Elbows;
- Audits.
It is these elements that make it possible to create a structure that exactly corresponds to the design documentation, and a check valve for the sewer system prevents the movement of drains in the opposite direction.

If you are planning to install the outer section of the drainage system, you should first of all familiarize yourself with all types of materials, paying particular attention to the corrugated pipes for external sewerage, to consider in detail their characteristics. Having chosen the most suitable materials in this way, make sure that the communication installation was carried out correctly.
By completing all these conditions, you will get an efficient, reliable and durable system that will run smoothly. And the video in this article will tell in more detail how to choose the right material and make the installation.
