The proper and high-quality operation of the sewerage system will depend not only on internal communications, but also on the pipeline laid outside. These structures are often forced to work in difficult conditions. Accordingly, these pipes must have the properties of resistance to operational wear, be durable and endure any temperature changes. The modern building materials market for creating such networks offers many variations of a wide variety of components. The main thing for the consumer is to carefully study all their characteristics and choose the most suitable option for themselves.

Conditionally, only 7 main qualities can be distinguished:
However, the long-term operation of external sewage will depend not only on the quality of the pipe material used, but also on the well-executed laying of the main, which is not possible without the use of various optional components, such as fittings, corners, plugs, etc. Moreover, additional elements must be compatible with the main segments.
This material for the manufacture of outdoor communications has been known for a long time and is often used. It is equally good for laying inside buildings and for creating highways outside. Cast iron is characterized by resistance to temperature extremes, is able to withstand various aggressive environments, has increased anti-corrosion qualities, because cast-iron models are necessarily coated with special compounds both inside and out. It is also possible to note their long service life (more than several decades), high strength of the material used, i.e. cast iron (specifically, its ability to withstand significant mechanical loads), which means the overall reliability of the entire assembled structure. In terms of installation, cast iron products do not require the use of any special tools, and a standard cement mortar can be used as a sealant. However, the material under consideration has three significant drawbacks:
IMPORTANT! The practice of the Soviet era shows that cast-iron pipelines can easily withstand up to 80 years of operation.
This material in the field under consideration has been used relatively recently, no more than two decades, but has already managed to become popular. There are several reasons for this:
Separately, it is worth mentioning the fragility of this material, therefore, you need to choose products from it carefully, carefully examining the product for cracks and chips. The same applies to the accuracy of transportation and the installation process, so that the products do not get damaged. In addition, ceramics will need to use optional elements (joints, adapters), because its length is limited by the properties of physical fragility. This product is supplied with cutting and socket, and the diameter can be from 10 to 60 centimeters.
Another type of material suitable for making external sewer lines. Portland cement and asbestos fiber products are quite light, so their installation is not particularly difficult. They have a number of important qualities, such as: they successfully resist the formation of internal growths, steadily conduct chemically aggressive substances inside themselves (which implies the possibility of running through the system of any liquid substances), have a long service life, which is at least 50 and maximum 100 years. During installation, if necessary, trim the object, no special tools are needed, it is quite possible to get by with standard helpers.Yet, like the previous type, asbestos-cement variations are quite fragile, which means that careful transportation and installation is necessary. At the same time, at the time of purchase, each part must be carefully inspected for the presence of falcons or cracks.
Products from this material are quite popular, because they are suitable for the formation of sewer mains according to various complex schemes, with various dimensions and capacities. Corrugated polyethylene samples can easily endure both high and low temperatures (up to +100 Celsius, but only for a short period), are characterized by a long service life (tens of years), their inner surface does not allow the formation of monolithic deposits due to its own smoothness, and ease of installation does not require the use of special devices and tools for installation. It is also worth noting that it is corrugated polypropylene that has special strength, because it consists of two layers:
The parts of the highway themselves can be laid over very long distances, fastening its individual components using the cold welding method. However, this material is not recommended for placement in an area exposed to direct sunlight.
This material, due to its fragility, is not often used for the installation of an external sewer system. It is customary to equip private houses and country stormwater with such designs. The advantages of this material include:
These plastic products, despite their wear resistance, are easily cut with a saw for metal, while not forming cracks and permanent chips in the place of cutting. The market for optional accessories for these sewer samples is very wide, the required additional item (fittings, etc.) is very easy to find in any hardware store.
This material is probably the best in terms of using it for the production of external sewer pipes. This is due to its technical, physical and operational properties. Today's market can offer three main types of PVC pipes:
PVC pipes are distinguished by easy installation, resistance to many chemically aggressive substances, low weight (availability of manual installation), increased strength and frost resistance, a smooth surface inside that does not retain solid fragments in drains, low cost and long service life.
IMPORTANT! PVC pipes still should not be used on highways where the passing liquid will have temperatures of +60 and above degrees Celsius - this can lead to expansion of the material due to heating. Installation is simple and does not require special skills.
It will consist of the following indicators:
Outdoor PVC sewerage is considered the next generation main, which will soon replace all other types of pipes from household systems. This is due to the installation features and the ability to work with high pressure up to 10 MegaPascals. Many installation options will allow you to assemble the desired design with ease:
Installation of external sewage in any case will require the availability of project documentation, no matter how simple its design may be - it is necessary to calculate the dimensions of the entire system, select material, count the number of joints and turns. Next, you should purchase all the building materials, acquire the necessary tools and you can begin the installation process. It will include the following steps:
When selecting pipes for outdoor sewage in a store, you need to pay attention to the following points:
IMPORTANT! Experts strongly do not recommend the use of gray pipes for laying external networks. They are barely visible on the ground, so it's much easier to inadvertently damage them.

Every year the choice of pipes for external sewerage is becoming more extensive and rich. Therefore, some private developers often ask themselves the question - “Which pipes are better for these systems?”. At the same time, there is a desire to find out which of the samples on the market will be more durable and cheaper. Everyone wants to get the most reliable and durable product. From this it is clear that this issue should be approached with all care, since the operation of the entire sewer system located outside will depend on the type of product.
