PVC pipe 50 sizes. PVC sewer pipe diameter: do-it-yourself pipe selection and installation

Until now, not all users understand the difference between pipe diameter designations.

1. D is the outer diameter of the pipe. This size is required for the selection of sockets, couplings, angles, threaded connections and other mounting and connecting plumbing fittings. It is he who is indicated on the marking, he will be blown off to navigate while compiling the list of elements sewer system.
2. d- inner diameter pipes. The dimensions of internal shut-off automatic and semi-automatic valves are attached to it, the speed of movement of fluid flows is calculated. Wall thickness sewer pipes determined by the difference between the outer and inner diameters. The inner diameter can be calculated using the formula d = D - 2S. S is the wall thickness.
3. D y - conditional pass. The value is used mainly by specialists, for ordinary consumers this parameter is not decisive, many have not heard about it at all.

Plastic pipeline with a diameter of 5 cm

Carrying out construction and repair work does not do without installing or replacing sewers. Iron and cast iron sections are gradually becoming a thing of the past. They are heavy, prone to corrosion and have a high price. Their use makes sense only at those facilities that experience a high operational load.

To create internal sewer systems in residential buildings, state and commercial organizations, shopping, entertainment and sports centers, plastic pipes of 50 mm diameter are used. These products have excellent characteristics and weight positive qualities. Their use allows you to carry out plumbing work quickly and efficiently.

Application area

Application plastic pipes wires

Due to its numerous advantages and various sizes, 50 mm sewer plastic pipes have a fairly wide range of applications.

According to the way they are used, they are divided into the following categories:

1. For the construction of an internal sewer system.
2. For arranging external sewerage.
3. To create a rainwater drainage system.
4. For the arrangement of water supply systems.

Based on the purpose, the walls of the products have different thicknesses and materials of manufacture. The most durable are those released for pressure systems. Plastic pipes 50 mm for internal highways have the least strength, as they do not experience strong impact. They are used to withdraw Wastewater from kitchen sinks, washbasins and bathtubs. But, even they have enough strength to withstand swipe or bend.

On a note: For ease of use, fragments for arranging an external drain are painted in bright Orange color. This draws attention to them, which helps prevent the destruction of the drain system.

Internal systems can be assembled in white, black and gray material. The most practical is gray plastic. On its surface, dust and scratches are practically not visible.

For ease of use, the following elements are used when assembling sewer systems:

• tees to create a branched highway;
• adapters for inserting 50 mm plastic pipes into 110 mm risers;
• couplings for connecting identical fragments;
• corners for the device of turns of the highway;
• plugs.

Fittings have greater strength than pipeline products. For guaranteed insulation, special glue and sealant can be used. Given that rubber gaskets fail quickly, you can purchase a set of spare gaskets.

Characteristics of sewer pipes with a diameter of 50 mm

When designing a sewer system, you need to rely on the properties of the material to be used. This will help to avoid mistakes and subsequent alterations.

Main indicators and dimensions sewer PVC 50 mm pipes are as follows:

• outer diameter - 50 mm;
• inner diameter - 45 mm;
• wall thickness - 22 mm;
• production material - polyvinyl chloride, non-combustible;
• length of one section - 25, 50, 75, 100, 150, 200 and 300 cm;
• operating temperature - from - 40 ° С to + 90 ° С;
• impact strength - 2.2 kg / 1 p.m;
• connection method - bell-shaped.

Assembly of sewer systems is carried out by joining parts in sockets or using fittings. Cutting of blanks is carried out with a hacksaw for metal. Fastening to the surface is carried out using clamps. The walls of the pipes are quite strong.

Important detail: The technical characteristics of the 50 mm PVC sewer pipe allow it to be poured with liquid concrete. This can be used for laying various communications in walls and horizontal slabs.

Features of the operation of plastic pipelines

Sewer PVC pipes 50 mm do not need to create greenhouse conditions for transportation, storage and operation.

When working with these products, you need to follow a few rules:

1. Do not use them for the construction of a fire water supply.
2. Sawing blanks only hand tools. Bulgarian can strongly melt their edges. After cutting, the cut edges are carefully cleaned of burrs.
3. To avoid distortion, store products in a horizontal position.
4. Fragments will be easier to join if the rubber gaskets are greased with petroleum jelly or silicone.

Assembling a sewer system is a fairly simple matter that is accessible even to a beginner.

Video about docking sewer pipelines of different sizes

Sewer plastic pipes in many areas of human activity have almost completely replaced traditional metal pipes today. The first one is based on:

• polyethylene;
• polyvinyl chloride;
• polypropylene;
• polybutylene.

The most popular for arranging modern sewer systems are PVC pipes, because they are resistant to aggressive substances that are in domestic and industrial wastewater. Negative impact can also have those elements that are in the ground.

Why you should use plastic

If we are talking about high-quality plastic pipes for laying sewers, then they have an ideal smooth surface, therefore, during operation, clogging occurs extremely rarely. During installation, there is no need to use any special tool, a hacksaw will be enough for cutting, and its fine teeth practically do not form burrs.

Key Features

Sewer plastic pipes are made from complex polymer compounds that are obtained during use. the latest technologies. This guarantees durability and reliability. If you want to choose especially durable products, then metal-polymer sewer pipes should be preferred.

Plastic pipes are quite easy to install, their laying requires less labor, this applies not only to the inside of the house. Such products are characterized by excellent throughput, they are easy to bend at a certain angle. Pipes can be laid independently. They have many benefits, including:

• reasonable cost;
• no need for cathodic protection;
• low thermal conductivity;
• reliable protection against the spread of viruses and bacteria;
• durability;
• resistance to chemical influences, corrosion and external aggressive environment;
• slight weight.

Sewer plastic pipes are ready to serve more than 50 years. They do not require constant maintenance.

Size Information

The described products can have a variety of sizes. If we are talking about an impressive diameter, then it is designed for an increased load, therefore, such pipes are installed to service buildings of social facilities, cottages and apartment buildings. For example, a diameter of 200 mm is suitable for a hospital, hotel or sauna.

If the diameter is increased to 300 mm, then such a pipe is suitable for the operation of industrial facilities. In individual construction, products of small diameter are required. A 150 mm riser will not be fully utilized, even if there are several bathrooms in the house. Square pipes can be used to solve the problems of irrigating personal plots. To organize drains from individual appliances such as a washbasin, shower and bath, you can use 75 mm pipes.

To ensure the operation of the toilet, it is necessary to use a pipe of 100 or 110 mm. When choosing dimensions, it is also important to take into account the wall thickness, which will depend on the diameter of the pipe. If the cross section is 160 mm, then the wall thickness will be 3.9 mm. In this case, a parameter of 110 mm will indicate that the wall thickness is 3 mm.

The weight of the pipe also depends on the diameter. For example, a 160 mm pipe weighs 2 kg, while a 110 mm pipe will give a weight of 1 kg. Sewer plastic pipes also have a certain length. According to state standards, manufacturers produce separate segments from 1 to 6 m, while the step will be 1 m.

Specifications

Plastic sewer pipe, the characteristics of which you should know before purchasing this product, has high mechanical strength. This is due to the three-layer manufacturing technology and external corrugation. That is why these elements can be installed to a depth of up to 8 m. The pipes are resistant to aggressive environments. This is especially true for PVC-U materials, because they are used to transport gases and chemical liquids.

The internal pressure will depend on the wall thickness and design, the maximum value can be up to 16 bar, while the minimum is 6 bar. The main disadvantage of these pipes is the temperature limitation. Maximum temperature is 65 °C, while the minimum is -10 °C.

Some models allow short-term exposure to temperatures up to +90 °C. Specific gravity may vary depending on the wall thickness and diameter, but on average it is 2 kg per running meter. At break, the maximum tensile strength is 50 MPa.

Characteristics of plastic sewer pipes for indoor laying

The sizes of plastic sewer pipes have been mentioned above. But this parameter cannot be called the only one that should be interested in when buying these products. For example, it is important to pay attention also to the color that indicates the purpose.

A gray tint indicates that you have a pipe in front of you for internal sewerage. It is distinguished by the smoothness of the walls, and is connected by a bell. The most popular sizes are: 32, 40, 50 and 110 mm. The length can vary from 315 to 3000 mm. Considering the stiffness conditions, the wall thickness should be selected. However, for gravity systems, this parameter cannot be less than 1.8 mm.

Characteristics of pipes for external sewage

External sewer plastic pipes are usually yellow or orange in color. They are used for laying outside and are operated under more severe conditions. This leads to the fact that they have their own list of wall thicknesses for each diameter. For example, for a 200 mm diameter, the wall thickness would be 3.9 mm. This applies to pipes for light conditions, they are laid to a depth of 4 meters.

With the aforementioned diameter, the wall thickness will be 4.9 mm, if the pipes are operated under medium hardness conditions, and they will be buried by 6 meters. The wall thickness will be increased to 5.9 mm if the depth reaches 8 meters and the hardness conditions are severe.

The cost of sewer plastic pipes

A plastic sewer pipe 50 mm is a product where the diameter is indicated. You will have to pay 94 rubles for the product. In this case, the wall thickness will be 3.2 mm. In this case, we are talking about the stiffness class SN 4. A sewer plastic pipe 110 mm will cost the consumer 200 rubles. The wall thickness remains the same. With an increase in diameter to 160 mm, the price rises to 579 rubles.

Connection Features

Plastic sewer pipes must be securely sealed and joined to each other. Ultimately, the master must receive a holistic design. For this, universal fittings are used, among them:

• knee;
• tee fittings;
• siphons.

A tee Y-fitting is used for connection at an angle of 45 °C. If it is necessary to form a right angle, a T-Y fitting should be used. If you want to connect a pipe of a larger diameter with a thinner pipe, then a sleeve is put on the socket, which allows you to reduce the diameter.

To eliminate blockages, experts recommend less frequent use of any kind of connection. Before connecting sewer plastic pipes, the structures should be cleaned, this is necessary when the pipe is soldered with a socket. If irregularities form on the inner wall, they will collect solid particles from the drains. When connecting with force, you can use a lubricant like soap, glycerin or grease.

Installation

The dimensions of the plastic sewer pipes must be selected by you before you start laying the system. Next, you need to follow the technology. At the first stage, the elements are adjusted, while the master needs to check the compliance of the slopes and angles. You can markup so as not to get confused in in large numbers nodes.

In the next step, the elements are connected to each other. It is important to check that the product fits into the socket by a third of the seat. In this case, no special efforts should be made. For tightness, the joints are glued with a special compound. After applying it, you can put on the fitting. To create a branched system, tees or other distribution elements can be used. After completion of work, it is important to check the tightness of the system within an hour. If the leak is not detected, then the installation work was carried out successfully and efficiently.

Features of the arrangement of the sewerage system using plastic pipes

Plastic sewer pipes, the prices of which were mentioned above, must be laid with a certain slope, which will ensure the unhindered removal of waste and sewage.

If the slope is too large, then growths will form on the inner walls, which over time will lead to the formation of blockages and traffic jams. If the slope is made smaller or not provided at all, then the drains will not leave the house on their own, the system in this case will be inoperative. Plastic sewer pipes, the prices of which should interest you if you plan to use them when arranging the system, are used in conjunction with a metal fan pipe. It is required for ventilation and is set to a height of four meters. Its diameter usually varies from 50 to 110 mm.

When it comes to urban high-rise buildings, where through all the floors passes sewer riser, its diameter must match the outlet pipe from the toilet. This value is 110 mm. The removal of the pipe is carried out on the roof, it is left open. It will communicate with the atmosphere and eliminate vacuum, which could lead to the appearance of unpleasant odors.

When assembling the riser, it is important to strengthen the neck of each pipe with a clamp. If a compensating pipe is installed, then its fastening is carried out using the same technology. Do not assume that plastic pipes will be enough O-rings. Over time, they will certainly loosen, and the joints may lose their tightness.

Conclusion

Installation of plastic sewer pipes is quite often carried out under highways. In this case, the system should be located at a depth of one meter or more. If it is no longer possible to deepen the system, then it is necessary to carry out its pulling in a reinforced concrete box.

It is important not only to correctly lay the sewerage system from plastic pipes, but also to ensure operation in accordance with the rules. For cleaning sewer risers, steel wire is used, which is not suitable for plastic structures. This is due to the fact that the wire can scratch the inner walls of the products. Therefore, it is recommended to use a soft cable that is protected by a rubber tip.

Wastewater disposal systems from modern polymer materials have huge advantages over obsolete structures made of cast iron and steel. In addition to the fact that a wide variety of sizes of sewer pipes are on sale pvc pipes, these products are excellent technical specifications. PVC pipes they are light in weight, easy to work with, polymer plastic is resistant to mechanical stress, chemically active liquids, fungus and mold. Of course, the durability, reliability and affordable cost of PVC plumbing pipes for sewerage, the dimensions of which allow you to create systems of any size and complexity, are not the least important. But, in order to carry out this work quickly and with high quality, you need to know what performance qualities are inherent in plastic sewer pipes.

Purpose of PVC pipes

The sizes of plastic sewer pipes are varied enough to transport a wide variety of liquids inside and outside the house to the end point, which can be general system collection of drains, a collector or a septic tank. Despite the fact that these products look almost the same, their purpose may not differ significantly depending on the model.

So, regardless of size, PVC sewer pipes have the following strength classification:

1. Heavy. Products have reinforced thick walls that can withstand the most extreme pressure, both from the outside and from the inside. They are used for laying pipelines under roads, on the territory of industrial and other facilities with heavy traffic.
2. Medium. Withstand loads from light ground and traffic cars. They have a fairly wide range of use in pressure and non-pressure systems.
3. Lungs. From pipes of this class, internal sewers, storm and drainage systems. They are laid underground exclusively in places with pedestrian traffic, since they do not have an adequate margin of safety. For the most part, they are used for arranging intra-house sewage systems of a non-pressure type.

With plastic pipes different sizes external and internal sewer structures, pressure and gravity systems for the removal of sewage, storm and melt water are being created. When choosing PVC sewer pipes, you need to take into account that the size and color of the products are different. So, sections and fittings for internal works have grey colour. PVC pipes for outdoor sewerage the dimensions are more impressive. Products of this series have a bright orange color. Regardless of type and size, plastic sewer pipes match perfectly in all respects.

Dimensions of plastic pipes

On a note: The efficiency and practicality of a drain system directly depends on the dimensions of the PVC sewer pipes that were used to assemble them.

This does not mean at all that you need to use the largest products. This approach is wrong, as it leads to unnecessary waste of money, effort and living space in the room. Everywhere you need to pick up the golden mean.

The standard sizes of plastic sewer pipes are divided according to the following indicators:

1. Length. The most common are sections with a length of 300 cm. They are most suitable for the repair and construction of houses with a ceiling height of 240-280 cm. There is practically no waste left. For the arrangement of non-standard premises, sections with a length of 50, 100, 150 and 200 cm can be purchased. This allows you to avoid unnecessary costs and unnecessary work associated with sawing into blanks and folding cut points.
2. Outside diameter. This value is indicated on the outside of the products. It is taken into account when designing a building and arranging an external sewage system, as the initial data for the manufacture of strobes in the walls, the depth and width of the trench. As a rule, for the arrangement of apartments and houses, parts with a diameter of 50 mm and 100 mm are used.
3. Inner diameter. This indicator determines the throughput of the system. It is measured in square centimeters or millimeters.
4. Wall thickness. This indicator determines the strength of the structure. It directly depends on the class of rigidity of the product. The wall thickness varies between 1.8-6 mm. For internal systems the thinnest pipes are enough. When arranging an external highway, it is worth choosing products with a maximum wall thickness to guarantee resistance to soil pressure.

When purchasing sections, you need to purchase fittings of the appropriate parameters. To avoid unwanted size discrepancies, it is advisable to buy a set of parts from the same manufacturer. The goods must be taken with a margin of up to 15% based on scraps and possible errors.

In the last decade, plastic sewer pipes have become ubiquitous. The reason for their popularity lies in the presence of the advantages of these products with a small number of disadvantages.

Advantages of plastic sewer pipes

Among the advantages of plastic products should be noted:

• low weight - for this reason, it is easy to create a sewer system using such pipes, because if necessary they can be easily moved and transported over long distances. Even a pipe 2 meters long can be mounted by one person, he obviously cannot cope with a cast-iron product;
• ease of installation - plastic is cut without problems and easily connected;
• durability - plastic sewer products are resistant to aggressive environments, corrosion, high humidity, so they can last long time. Manufacturers of these products usually give a 50-year warranty on them. As practice has shown, the service life of sewer plastic pipes is much longer;
• resistance to blockages - the fact is that their inner surface has almost no roughness, so dirt is deposited on it slowly. As a result, blockages rarely form. After installation is completed, cleaning will not be required soon;
• immunity to temperature changes - outdoor plastic sewer pipes are commercially available that can withstand frosty weather well.

Disadvantages of sewer pipes made of plastic:

• noisy operation - the sewer system made of plastic products makes noise during operation. This negative aspect is especially evident in apartment buildings, where drains from several apartments are connected to one riser;
• intolerance to high temperatures - the operating temperature of these products ranges from 40 to 90 degrees. In the case when the temperature of the drains exceeds these parameters, most types of plastic pipes soften. This shortcoming is not considered significant as the waste water temperature is not that high.

Types of plastic for sewer pipes

Types of plastic pipes for sewerage differ in the material of manufacture.

Polyethylene has the following features:

• resistance to active chemicals;
• immunity to low temperatures (in case of their decrease, polyethylene does not lose its physical properties, while the presence of an ice plug will only stretch the product, and after the ice melts, the pipe takes its original size);
• the presence of a slippery surface - nothing sticks to it;
• this material softens at low temperatures (at +80 degrees, even the most durable products become soft);
• working pressure equal to 2.5 - 16 atmospheres.

Polyvinyl chloride is considered the most popular plastic used for arranging sewer systems, since PVC is characterized by:

• resistance to alkaline media, most acids and mineral oils;
• depending on the brand of products with a density of 1.35 to 1.43 g / cm³;
• slow combustibility (polyvinyl chloride begins to decompose at a temperature of 120 degrees, releasing hydrogen chloride);
• poor conductivity of electricity;
• rigidity and elasticity, but impact can damage PVC;
• deformation at a temperature of more than +70 degrees;
• working pressure 6 - 46 atmospheres.

Polypropylene is usually used to create a water pressure system.

But sewer pipes made of this material are also on sale, which differs:

• low weight - it is lighter than other types of plastics;
• density equal to 0.91 g/cm³;
• abrasion resistance (polypropylene pipes are able to withstand drains with abrasive fractions);
• softening temperature, which is 140 degrees above zero, melting - 180 degrees;
• susceptibility to prolonged exposure to highly concentrated acids;
• the ability to collapse at a temperature of less than 5 degrees below zero, so the ice plug will destroy the system;
• operating pressure of about 20 atmospheres;
• welding connection.

Metal-polymer products (PEX-pipes). These products are characterized by strength and durability. This material is three-layer: polyethylene - aluminum - polyethylene. Due to the presence of a metal layer, the strength of the pipes is enhanced.

This material has the following features:

• operating temperature is from +40 to +95 degrees;
• just cut and bend;
• has high heat-reflecting and anti-corrosion parameters;
• the diameter of plastic sewer pipes of this type is 16-63 millimeters and therefore they are usually used when installing an internal sewer system.

The choice of plastic pipes for sewerage

Since the sewer system is internal and external, when sewer pipes are made, different plastic is used for them.
The choice depends on the requirements for the removal of wastewater.

outdoor option sewer network characterized by the following indicators:

• high strength, since soil pressure will be exerted on the structure;
• her throughput should ensure timely discharge of wastewater;
• resistance to corrosion and temperature changes;
• reliability of the connection of individual elements.

Other requirements are imposed on pipes for internal sewage, since the pipeline has more gentle loads on the network, the air temperature does not drop below zero, and the amount of drains from individual plumbing fixtures is less.

When choosing pipes, take into account their parameters:

• the inner diameter of plastic pipes for sewage is considered one of the most important characteristics, due to which the unhindered discharge of effluents is ensured at a certain point in the system;
• external diameter;
• wall thickness (affects the strength of the pipe);
• kind of plastic.

Also, when choosing plastic sewer pipes, their dimensions are great importance, this primarily concerns the length. Properly purchased items are a guarantee quality work sewerage system and its convenient installation.

Rigidity of the plastic pipe

Such a parameter of plastic pipes as strength differs for internal and external systems.

In order to distinguish them, manufacturers paint products in different colors(see photo):

• in light brown - pipes for arranging internal sewage;
• in orange-brown - for the external network.

Plastic sewer pipes differ according to the stiffness class:

• SN 2 - products are intended for laying pipelines in areas where there is no or limited traffic;
• SN 4 - products are used in areas with constant moderate traffic;
• SN 8 - this class of products is used in areas with intensive movement of heavy and light vehicles.

Dimensions and diameter of plastic sewer pipes

Manufacturers of sewer pipes must specify their outer diameter and wall thickness. Plumbing professionals for installation work you need to know the inside diameter. To determine it, the wall thickness is subtracted from the outer diameter.

Plastic pipes for sewerage have different sizes depending on their purpose.

Features of installation and operation

1. Since plastic is a light and thin material, it cannot absorb vibration and acoustic vibrations. This problem is solved by placing the pipeline in a special box or foam shell.
2. When connecting a pipe to a socket, it is necessary to remove the chamfer from its outer side and clean the burrs from the inside. If this is not done, in places where there are irregularities in the pipeline, a blockage will form.
3. When docking the elements of the system, you need to use a lubricant - for example, glycerin, grease.
4. To fix plastic pipes at a certain angle of inclination, plastic latches and clamps are used.
5. The neck of each of the pipes is fixed with a clamp, especially when installing a compensating pipe, since the sealing rings will obviously not be enough.
6. Hangers and clamps should be located on horizontal sections of the network every 50 centimeters.
7. The external pipeline is buried under dirt roads by more than 50 centimeters or hidden in a reinforced concrete box.
8. With an increased load on the ground, a corrugated plastic sewer pipe is used.

They clean plastic pipes with a plumbing cable with a rubber tip, or, in case of blockage, dismantle a section of the pipeline.
