Pipes and fittings - existence is impossible without them sewer system. The right choice These products are designed for trouble-free operation and long service life. Today there is huge selection types of fittings and pipes. What material they are made of, about the sizes and types, we will talk in this article.
What are sewer pipes
According to the method of water drainage distinguish the following types:
Plastic pipes for sewerage
- internal pipes - divert water from the source of consumption (, sinks). As a rule, they are painted in gray colors.
- external - produce a tap from houses and cottages, into the general sewer.
Attention! Pipes for external sewage, unlike internal ones, are made in orange, for easy detection in the ground.
By material from which pipes and fittings are made are divided into:
- cast iron. Most sewers are made from this material. It is strong, durable (70-85 years), withstands heavy loads. The disadvantages include high cost and installation problems associated with heavy weight. In addition, the inner walls of cast-iron pipes are rough, which makes it difficult for water to move, and build-ups form over time.
Cast iron pipes
- plastic. Pipes are made from this material for both internal and external sewage. Its main advantages are light weight, which facilitates the process of transportation and installation, relatively low cost, as well as smooth inner walls, which reduces the percentage of congestion. There are three types plastic pipes and fittings: PVC(mainly used for Wastewater. Withstand temperatures up to 70C, but are not resistant to aggressive environments and UV rays); polyethylene(used for pressure internal and external pipelines. Expand under the influence of hot water, withstand temperatures from -40 to +40. Not applicable for hot water) polypropylene(withstand high temperatures, resistant to acids and alkalis. Most often used to drain water from washing machines and dishwashers).
Fittings for PVC pipes (external sewerage)
- stainless steel pipes are not very popular due to their low resistance to corrosion.
- copper pipes are the most expensive, do not corrode and are neutral to the action of acidic and alkaline environments. But their main drawback is the ability to change the color and smell of water.
Fittings for external and internal sewerage
A fitting is a part of a pipeline designed to turn, connect, branch, change to another size, parts of pipes. For an external pipeline, the following types of fittings are distinguished:
Fittings for internal sewerage differ from external ones in color, wall thickness and diameter.
Types of fittings
Main indicators of pipes
- 25 mm for draining water from a washing machine and dishwasher;
- 32 mm from any kind of siphon;
- 50 mm for piping around the room;
- more than 110 mm for external sewerage.
So, if you decide to lay a sewer, you need to take into account all the basic indicators, the place of passage, the number of transitions and turns, in order to purchase the number of pipes and fittings you need. Properly selected material and dimensions will allow the sewerage system to serve for a long time and without failures.

We offer to buy pipes for internal sewerage in bulk, their use is possible both in residential and industrial and administrative buildings. The company's specialists provide qualified advice on all issues that have arisen. Delivery of the order is provided.
Professional preparation of the project of the internal sewer system provides for careful consideration of each of the stages.
One of the most important is the choice of pipe material. Along with traditional cast iron and asbestos structures, the market offers PVC pipes to the consumer.
Polyvinyl chloride has been known for a long time, but due to the laboriousness of the process and imperfect equipment, its widespread use has become possible only in our time.
The pipe production process consists in the use of several components, which, when mixed and heated, give a homogeneous plastic mass.
It includes the following materials:
- plasticizers - the main ingredient that gives the pipes their unique properties;
- stabilizers - necessary for the "strong" connection of polymer molecules to each other;
- a small part of PVC waste. The best analogue to them is the recycling of scrap metal for the production of new products.
The heated mass under pressure passes through a special form - an extruder. So for the first time it is possible to observe the formation of a sewer pipe blank.
There are 2 types of PVC:
- plasticized (PVC). Differs in the increased indicators of elasticity. But due to low strength characteristics, it is not used in the production of pipes;
- unplasticized PVC (PVC-U). Differs in rigid structure and resistance to many aggressive environments.
It is from the latter that pipes for internal sewage are made.
These pipes can be used for both pressure and gravity systems.
According to the connection method, they can be:
- without socket - socket connection;
- socket adhesive;
- socket mechanical.
The latter are the most popular for internal sewage.
The mechanism of connection with each other is implemented simply, but effectively. At one end of each product there is a special socket, the inner diameter of which coincides with the normalized outer one.
As an additional seal, a rubber ring is inserted into a special groove. To connect 2 pipes, it is enough to insert them into each other.
Photo: Irub socket connection Processing is also not difficult - you can reduce the size with a hacksaw.
Dimensions
One of the important parameters for all pipes are overall and internal dimensions.
These include:
- outside diameter;
- internal (working) diameter;
- wall thickness;
- pipe length.
According to current regulatory documents only the inner diameter and the strength parameter at the maximum allowable pressure are regulated.
Based on this, manufacturers currently produce PVC pipes of the following sizes:
| Outer d, mm | Internal d, mm | Wall thickness, mm | Pipe lengths, m |
| 32 | 30,2 | 1,8 | 0,35; 0,5; 1; 2 |
| 40 | 38,2 | 1,8 | |
| 50 | 48,2 | 1,8 | 0,35; 0,5; 1; 1,5; 2;3 |
| 110 | 107,8 | 2,2 |
An important role is played by the length of the connecting socket. For different diameters, its parameters must correspond to the outer diameter.
That is, for a pipe d 32 mm, the length of the socket is 32 mm. Moreover, the distance is measured from the end to the conical bevel.
It also directly affects its use in the internal sewerage system. The smaller it is, the worse the throughput of this section.
Therefore, when planning pipe laying, it is necessary that pipes run from the riser from a larger section to a smaller one.

The characteristics of the pipes largely depend on the manufacturer's compliance with the standards of production technology. But the problem is that at present there are guests only for pipes for pressure sewer systems.
In them you can find the nominal indicators of pressure, wall thickness, resistance to certain aggressive environments, etc. There are no such documents for non-pressure (gravity-flowing) systems.
Therefore, all manufacturers adhere (or try to adhere) to GOST for PVC-U pressure pipes.
Based on this, you can make a list of the following technical characteristics:
- operating temperature conditions: minimum -15°С maximum +65°С. Some models withstand short-term exposure without deformation, damage to the structure up to +90 ° C;
- nominal pressure - 0.16 MPa. Although for gravity sewers, this indicator is not significant. Much more important is its derivative - the wall thickness;
- specific gravity is about 2kg/m.p. As the diameter increases, it increases;
- the inner surface of the pipe has a good slip index, which allows drains to pass unhindered along the highway;
- resistance to many aggressive environments;
- subject to the rules of operation, the service life can reach 50 years;
- but other parameters are more important for the end user - advantages and disadvantages.
Advantages:
- affordable cost. Compared to other pipe materials PVC sewer has a very attractive price. This also applies to additional accessories - fittings;
- ease of installation. This does not require special tools. A hacksaw, a knife for end processing and lubrication are enough for a better entry of the pipe into the socket;
- good mechanical strength. Unplasticized PVC initially has this quality necessary for installation and operation;
- resistance to UV radiation;
- PVC dielectric. This means that the pipes do not conduct electricity and the whole system does not need grounding;
- absence of corrosion processes;
- smooth inner surface.
Flaws:
- limited temperature regime operation;
- poor soundproofing. Additional measures must be taken for outdoor installation;
- increased brittleness. With a decrease in temperature, this indicator increases proportionally;
Fitting
To implement a complex internal sewage system, additional connecting elements are required - fittings.
They serve for turns, branching and transition of the line from one diameter to another.
Knee
Photo: knee Serves for turns of the sewer system. It can differ in the angle of inclination - from 20 ° to 87 °.
Tee
Photo: tee It is necessary for branching the sewerage, and joining additional highways to the general system. It is also different, depending on the angle of rotation of the connecting pipe - from 20° to 87°.
Reduction
Photo: reduction Serves as a connecting element for 2 pipes of different diameters.
cross
Photo: cross It is used for simultaneous connection of 4 pipes at once into one common system.
In addition to the fittings described above, there are a number of additional elements that are necessary to create a complete internal sewage system:
- inspection hatch - with its help, a visual check of the condition of the inner surface of the pipe is carried out;

Currently, there is only GOST for pipes made of unplasticized polyvinyl chloride for pressure sewage - GOST R 51613-2000.
It specifies standards for the following criteria:
- dimensions and dimensions of pressure pipes;
- safety during installation and operation;
- transportation and storage rules;
- test methodology.
As mentioned above, pipes for gravity sewerage are manufactured in accordance with this GOST.
Prices
Despite its low cost, it is still worth knowing the estimated price of pipes. It will directly depend on it, and in particular, its hollow estimate.
As you can see, the cost of pipes is really more than affordable. But this factor should not affect the quality of the internal sewerage project.
