Plumbing pipes pvc dimensions. Sewer pipes

The quality and durability of the sewer network is one of the important conditions for a comfortable and safe living in the home.

Plastic pipes are gradually displacing products from other materials in the field of sanitation. This is explained by a whole range of advantages of plastic. Especially popular is the plumbing pipes, adapters and fittings made of PVC for sewerage.

PVC is decoded as polyvinyl chloride. This substance is a product of polymerization of vinyl chloride, characterized by high strength, durability, resistance to aggressive media, ultraviolet radiation   and corrosion.

In addition, pipes made of polyvinyl chloride have more several positive characteristics, causing their growing popularity in the arrangement of the sewage system:

1. Light weight   simplifies not only the delivery, but also the installation and dismantling of products.
2. The main attractive property is low price. PVC products cost much less than their cast iron or steel counterparts.
3. The structure of pipes and a huge number of different types of fittings   allows you to carry out the installation without using special tools and with your own hands.

But there is a product of polyvinyl chloride and a number of shortcomings:

• the material is sensitive to frost;
• there is a risk of deformation at a temperature of 70 degrees and above;
• the movement of sewage through the pipeline is accompanied by noise.

Structure and types

Most PVC pipes on one side have an extension called a bell. It is necessary for the connection. The other end is smooth, it is inserted into the socket when assembled. The fineness of the structure, composition, and color depend on the type of product.

Internal sewage pipelines and adapters

For arrangement of inter house cabling and riser apply products of gray color, made of unplasticized polyvinyl chloride.

Sewer pipes   and PVC fittings for internal sewerage   smooth, the sizes and diameters can be various. The most popular cross section is 5 and 11 cm.

In the internal sewerage system, fittings with a rubber seal are used to connect the elements to each other or sanitary equipment, as well as to equip the pipeline turns. According to the function to be performed adapters can be of the following types:

• clutch, used when impossibility of spigot connection or during repair;
• reduction, necessary for joining elements of different diameters;
• inspection hatch   to check and maintain the system in case of clogging;
• tee, having angles of 45, 90 and 67 degrees, or a cross with angles of 45 and 90 degrees for connecting several pipes;
• rotary tap   for sewage from PVC in 30, 45 and 90 degrees;
• compensating branch pipe, used during the repair.

Products for external sewerage

Visually, the elements used for the arrangement of the external sewerage network differ in color. They yellow or orange. Their walls can be smooth and single-layered or corrugated three-layered.

In this group, the strength and wall thickness play an important role. In accordance with this parameter, smooth tubes are divided into 3 categories:

• SN2not suitable for heavy loads;
• SN4   can be laid under a road for which there is not much traffic;
• SN8- the most durable products, which can be laid at great depths and under busy roads.

Pipes for outdoor sewage are available in diameter from 11 to 63 cm.

When building an out-of-home network, adapters are also used:

• clutch;
• bends having angles of 15, 30, 45, 67 and 90 degrees;
• rectangular bends with two funnels;
• check valves;
• siphons with two knees;
• inspection hatch;
• reduction;
• trehrastubny tee with a right angle;
• tee with angles of 45, 67 and 90 degrees and a single-plane cross with a right angle.

Elements of forced water disposal

In addition, they are divided into 2 categories according to the method of assembly:

• with the help of classical trumpets;
• adhesive method using special fittings.

How to choose?

The type of sewage and installation location are one of the important parameters when selecting elements of the sewage network. In this case, the size and strength characteristics play an important role.

Calculations of the internal pipe section are rather complicated, but there are many years of practical experience:

1. To divert drains from sinks, shower and similar equipment of private housing is sufficient inner tubes   diameter of 5 cm.
2. Wastewater from the toilet is made by a pipeline of 11 cm.
3. Stoyak in apartments and private houses with a full-fledged bathroom should have a diameter of 11 cm. In multi-storey buildings, vertical pipelines of 15 cm are often installed.
4. If to horizontal line, collecting and discharging drains from the house, several risers are connected, then the cross section of the pipeline should be 20 cm.
5. A branch that brings sewage from plumbing to vertical pipe, should not be in diameter less than the riser.

For an important role the strength of the walls indicated above.

Also, before buying, you need to draw a sewer network diagram on a scale. It should show not only the length of the pipes and their passage points, but also all necessary fittings.

Installation rules

In the vast majority of sewage systems, the drains are moved by gravity. Therefore, it is important to comply with the installation. The angle of inclination is too large or too small. The value of this parameter depends on the section of the pipeline:

• for 50 mm - 3 cm for each meter;
• for 110 mm - 2с mm;
• 160 mm - 0,8 cm;
• 200 mm - 0.7 cm.

In addition, when installing products from PVC it is necessary to take into account a number of other features:

1. In connection with the instability to the action of low temperatures, the external pipeline is laid below the zero point of the soil. If there is no such possibility, then the branch must be insulated.
2. Cutting of PVC products is carried out with the help of a special machine, a cable or a saw with fine denticles. All the burrs are removed.
3. During the assembly process, check the connection location. At the same time, in the last 1/3 of the socket the pipe must go in with effort.
4. PVC elements are recommended to be glued additionally with the help of special compounds. An exception - hard-to-reach places, it is better to leave the connection only with the help of a cuff.
5. During assembly, the joints are additionally sealed with a small amount of silicone.
6. AT open systems   internal sewer pipes are fixed with clamps to the wall. The distance between the riser fasteners should be 80-100 cm, and on the horizontal wiring - 40 cm.

After the installation is complete, close the outlet to the external sewer and fill the system with water. This will allow us to evaluate the tightness of joints.

Properly selected and installed sewage network of PVC rarely clogs and serves for a long time, not bringing inconvenience. At the same time it is budgetary and easy to assemble by oneself.

Sewage pipes without a doubt are the basis of the entire system of drains. Such an inseparable detail of water disposal was previously performed in rough metal to ensure strength, durability, resistance to fire. But even such indisputable pluses attract the corresponding disadvantages, the most tangible of which is a huge weight, because of which certain editing difficulties are created. The uneven and rough inner side contributes to the accumulation of deposits, which leads to frequent blockages. and the metal itself (especially if it is black steel, and not the usual cast iron) is naturally prone to corrosion.

In our time, the development of technologies for the production of polymer materials has made it possible to create sewer pipes of a new generation. Made of plastic, they quickly gained popularity, because most of the deficiencies that cast-iron predecessors had been eliminated were eliminated. At present, the catalog of pipes includes two leading positions.

PVC pipes are common in the market due to their versatility. Resistance to temperatures up to 75 ° C, damage, chemicals and fouling provided reliability, and ease of installation and affordable price   guaranteed a wide application, especially in external sewerage and installation of risers. The main problem is the toxicity of such products in the combustion, processing and disposal.

Analogues from polypropylene are more often laid in the premises due to a number of special advantages. One of the main advantages is the high throughput, which is achieved through a smooth surface inside. They are also frost-hardy and do not burst when water freezes, they work stably with an increase in temperature to 95º, which is much better than PVC. The degree of sound absorption provided will have a positive effect in apartment buildings. The tubes themselves are rather soft and, therefore, more durable under the influence of physical strength, facilitating transportation and installation work, however, when heated to the maximum threshold, they tend to expand the walls and lose their strength. That is why they require an additional installation of compensating nozzles.

Since both species provide a service life of at least 50 years, there is no point in talking about superiority. The best option is determined by individual conditions, and you can always buy sewer pipes from the material most suitable for your requirements in any sanitary ware shop.

Such products as plumbing pipes and pvc adapters for sanitary purposes can be made from different raw materials (not necessarily PVC), but it is used more often, since such a solution is the most practical.

In the composition of the material in question, if it is intended to be used for the production of waste water engineering communications, do not include plasticizers.

What is the diversity of the products in question in the current market of sanitary components?

All existing sewer pipes can be distinguished by the following features:

What the color says

1. Area of ​​operation. On this basis, the products in question are for indoor use or for outdoor use. Products for internal use are color-coded (gray or white color), the diameters of such parts are usually small, the range of thermal loads is high. are painted in orange, they are multilayered.
2. Terms of Use. Such products can be pressure (developed for use under pressure), non-pressure (for example) and corrugated.

Classification of auxiliary parts for the assembly of a drainage structure and a water pipe is carried out as follows:

• On the accessibility of the connection by the funnels. If it does not exist, it becomes urgent to use a coupling.
• In the format of those situations where there is a need to connect parts whose dimensions are different, reductive-type components are used.
• Tees are used to combine several parts in the context of one section of the product.
• For the distribution of individual parts, rotary adapters with a radius of 15 to 90 degrees are used.

Parts for internal use

What should you know about the products in question?

Experienced masters advise you to choose the soft parts for water supply and drainage based on the following parameters:

What are the main advantages of a sewer system assembled from PVC?

Among the most significant advantages of the parts in question are the following positive features:

What does the system look like after the assembly

• The impossibility of clogging the system ensured by the maximum smoothness of the surface inside the product.
• High degree of opposition to the influence of alkalis and other aggressive compounds.
•   if compared with analogues made from other varieties of raw materials.
• Total resistance to corrosion.
• High. Harmless remains a long warm-up at a temperature of 70 degrees or a short-term at 140 degrees.
• An impressive service life, which often reaches 100 years.

What is the cost of the products in different regions of Russia?

The price of a meter length of pipe for outdoor use in Yekaterinburg is 185 rubles. Buy a similar product, but in Nizhny Novgorod, you can already for 162 rubles. In St. Petersburg (St. Petersburg) the same products will cost the buyer 110 rubles when buying one meter of the product. The cost can vary significantly depending on the following aspects of the purchase:

1. Length of the product. Here it is worthwhile to understand that we are not talking not about multiplying the cost of one meter by the running meter, but about the fact that with increasing the footage, the cost of one meter gradually decreases.
2. Wall thickness of the part.
3. The factory is the manufacturer.

Prices corrugated pipes   different classes

As can be seen from the comparison of prices in the region, the cost of parts depends not only on technical, but also on regional parameters, but this dependence does not significantly change the price of the product. If we compare water supply, then it should be said that the products of the second type differ in the following operational parameters:

1. Resistance to high temperatures. It is only relevant when it comes to pipes for hot water supply or heating.
2. High flexibility. If plasticizers are not added to the sewer parts - there is no particular need for this, the plumbing components are sufficiently plastic, which in itself is dictated by the current need.
