PVC plumbing pipes for sewerage dimensions. Sizes of PVC sewer pipes - what are they? Catalog of fittings for PVC sewerage and prices for products
Plastic pipeline with a diameter of 5 cm
Carrying out construction and repair work cannot be done without installing or replacing a sewer system. Iron and cast iron sections are gradually becoming a thing of the past. They are heavy, susceptible to corrosion and have a high price. Their use makes sense only at those facilities that experience high operational load.
To create internal sewer systems in residential buildings, government and commercial organizations, shopping, entertainment and sports centers, plastic pipes of 50 mm diameter are used. These products have excellent characteristics and a lot of positive qualities. Their use allows for plumbing work
quickly and efficiently.
Advantages of 50 mm PVC sewer pipes

Application area
Application plastic pipes wires
Due to its many advantages and varied sizes, 50 mm plastic sewer pipes have quite wide range applications.
According to the method of use, they are divided into the following categories:
- For the construction of an internal sewer system.
- For the installation of external sewage systems.
- To create a rainwater drainage system.
- For the installation of water pressure systems.
Based on their purpose, the walls of the products have different thicknesses and materials of manufacture. The most durable are those produced for pressure systems. 50 mm plastic pipes for internal lines have the least strength, as they do not experience strong impact. They are used to divert Wastewater from kitchen sinks, washbasins and bathtubs. But even they are strong enough to withstand swipe or bend.
On a note: For ease of use, fragments for arranging the external drain are painted bright orange. This draws attention to them, which helps prevent destruction of the drain system.
Internal systems can be assembled from white, black and gray material. The most practical is gray plastic. Dust and scratches are practically invisible on its surface.
For ease of use, the following elements are used when assembling sewer systems:
- tees for creating a branched highway;
- adapters for inserting 50 mm plastic pipes into 110 mm risers;
- couplings for connecting identical fragments;
- angles for making highway turns;
- stubs.
Fittings are more durable than pipeline products. To ensure insulation, special glue and sealant can be used. Given the fact that rubber gaskets They 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 that will be used. This will help avoid mistakes and subsequent rework.
The main indicators and dimensions of a 50 mm PVC sewer pipe are as follows:
- outer diameter - 50 mm;
- internal diameter - 45 mm;
- wall thickness - 22 mm;
- manufacturing material - polyvinyl chloride, which does not support combustion;
- length of one section - 25, 50, 75, 100, 150, 200 and 300 cm;
- operating temperature - from - 40° C to + 90° C;
- impact strength - 2.2 kg/1 running meter;
- connection method - socket.
The assembly of sewer systems is carried out by joining parts in sockets or using fittings. Cutting of workpieces 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 filled liquid concrete. This can be used for laying various communications in walls and horizontal slabs.
Features of the operation of plastic pipelines
PVC sewer pipes 50 mm do not require the creation of greenhouse conditions for transportation, storage and operation.
When working with these products, you must adhere to several rules:
- Do not use them for the construction of fire water pipelines.
- Only saw workpieces hand tools. The grinder can greatly melt their edges. After cutting, the edges of the cut are thoroughly cleaned of burrs.
- To avoid bending, products should be stored horizontally.
- It will be easier to join the fragments if the rubber gaskets are lubricated with Vaseline or silicone.
Assembling a sewer system is a fairly simple task, which is accessible even to a beginner.

This article discusses in detail the features of such products as PVC pipes for sewerage: the sizes and prices of plastic elements and additional components used for installing a drainage system. In the text you can find a classification of pipes, their advantages and disadvantages, as well as an overview of the catalogs offered construction stores. This information can be used to select and purchase PVC products for sewer installation.
The sewerage system is constructed on the basis of pipes, which are an integral part of the system. During operation, these elements are subject to static and dynamic loads, so the selection of products should be approached thoroughly and attention should be paid technical specifications.
Polyvinyl chloride products are widely used for the construction of both internal and external sewerage systems. Among other polymer products, they are considered the most popular and in demand. These cylindrical plastic products are made from polyvinyl chloride thermoplastic. This material has one advantageous property, due to which PVC pipes acquire improved characteristics. The fact is that polyvinyl chloride thermoplastic retains its shape well after heat treatment and extrusion.
According to GOST 51613-2000, free-flow PVC pipes for sewerage are tested for impact strength using the Charpy system. The maximum permissible number of elements that are subject to destruction should not exceed 10%.
Note! A slight change in the length of the elements after heating is allowed, but not more than 5%.
GOST also defines standard sizes plastic pipes for sewerage, as well as maximum deviations from the parameters that are permissible in quality products. Polyvinyl chloride contains two components - stabilized chlorine and ethylene. In order to improve performance characteristics, manufacturers add various additives to thermoplastic mixtures. As a result, under the influence of high pressure, a composite connection with a high margin of safety is obtained.
Why is it profitable to buy PVC pipes for sewerage?
Polymer products have many advantages. Manufacturers have made plastic pipes lightweight, while maintaining enough high level strength. The cost is affordable for most buyers, so consumers prefer this type of product.
To the number the most important advantages Advantageous performance characteristics can also be attributed. The inner walls of polymer pipes have a smooth surface with a slight presence of longitudinal stripes and waviness, so the likelihood of blockages caused by the accumulation of fecal fractions or growths is extremely low. Plastic is not subject to corrosion and is resistant to aggressive environments.
PVC pipes are ideal for the construction of pressure sewers. Moreover, installation of the system can be done with my own hands. This does not require the use of special equipment. A wide variety of sizes and mounting elements are available, which greatly simplifies the design and installation of pipeline wiring.
Products intended for laying external sewerage, frost resistance is inherent. The effective operational service life of pipes made from polymers exceeds 50 years. If the installation technology requirements are strictly followed, the sewer line will not be subject to displacement. Docking points often diverge when the groundwater level changes. But if there were no violations during the installation process, even in such conditions the system of polymer pipes remains sealed.
Important! Under the influence of ultraviolet radiation, the performance characteristics of pipes are reduced. Therefore, it is not recommended to store products in places where they will be exposed to direct sunlight.
Types of plumbing pipes and PVC adapters for sewerage
Range plastic products is very wide, thanks to which consumers can buy plastic pipes for sewerage of any modification and purpose. Taking into account the purpose and operating conditions, three categories of elements for highway construction can be distinguished.
All of them are in full compliance with the main standard sizes. Products with a lightweight design (SN-2) are used for laying sewerage in the pedestrian sidewalk area. The scope of their application also extends to recreation areas with green spaces, as well as areas that are not subject to traffic loads.
Pipes with average parameters (SN-4) are laid in areas where there is little traffic. Heavy type pipes (SN-8) are provided especially for industrial areas. These products are suitable for organizing a sewer system in areas with high traffic flow.
In addition to straight pipes for sewer construction, they are used connecting elements. With their help, you can organize turns of the line (fittings equipped with a rubber seal). They are also used to form connections between the toilet and the sewer system from plastic pipes or joints between other elements.
The following types of adapters are available for sale:
- couplings for network maintenance;
- reductions connecting elements with differences in section size;
- tees and crosses for forming the distribution of several pipes;
- rotary bends;
- expansion pipes for repair work.
In addition, you can buy plastic sewer hatches in stores to carry out inspections. These elements are also used for servicing the system when blockages occur.
PVC pipes for sewerage: sizes and prices of products
The most popular diameter of sewer pipes PVC pipes- 110 mm. Such products are lightweight and do not cause difficulties during installation. Pipes intended for the construction of an external system can have a two-, one-, or three-layer structure. The outer layer is made of non-plasticized PVC. In three-layer products, the inner layers are made of foam material having a porous structure. It is a recycled product.
The pipe walls are connected simultaneously using “hot” technology. The result is a cylindrical product with a monolithic structure. Due to the cavities that form between the walls, it is possible to reduce the weight of the pipe.
Classification of products by ring stiffness class:
- L – lightweight products that are laid to a depth of 80-200 cm.
- N – pipes of medium hardness, intended for installation at a depth of 2-6 m.
- S - rigid products with large wall thicknesses that can withstand loads at a depth of up to 8 m.
Helpful advice! To organize an external system, it is recommended to use double-layer pipes with a corrugated structure. Thanks to the presence of stiffening ribs on the outside, the strength of the products increases.
Ring stiffness is marked with the abbreviation SN. Technical specifications pressure pipes and elements for systems where the movement of wastewater is carried out by gravity are completely different. In each case, the sewerage system is subjected to different loads: pressure pressure or the influence of gravity. For this reason, prices for pressure-type sewer plastic pipes are significantly higher than for elements for gravity systems.
Pressure pipes are available in three variations, able to cope with the influence of pressure of 10, 6 and 12.5 kg per cm².
Dimensions and prices of plastic pipes for sewerage: external system
For the construction of external and internal sewer systems, products of different sections are used.
Typical diameter sizes of plastic pipes for sewerage:
- 110 mm – the minimum cross-sectional size for pipes for external use, used for drainage of wastewater in summer cottages;
- 315 mm - products with this cross-section are intended for the construction of a common sewer system serving several houses;
- 630 mm – pipes with maximum size sections for the construction of a highway capable of serving a small village.
In addition, to work with external system you will need to buy a sewer pumping hose made of polyvinyl chloride.
Prices for fecal hoses:
| Manufacturer | price, rub. |
| Pedrollo TR (10 m) | 1650 |
| Omnigena (100 m) | 2500 |

Price of PVC sewer pipes for internal sewerage
Pipes intended for arranging the internal drainage system are made in gray color. They have a low price, since these products are characterized by a light rigidity class and are completely unsuitable for outdoor work. The most popular PVC pipes for sewerage are 50 mm in diameter. Although there are other section sizes on sale - 32, 40 and 110 mm.
The inner walls of gray pipes are smooth. The elements are connected to each other using the “socket” technology. The length varies from 25 cm to 3 m, although non-standard sizes are also found.
Note! The branch connecting the plumbing to the vertical pipe must correspond to the diameter of the riser. The use of a smaller section is not allowed.
To build a drainage system in a bathroom, it is recommended to use pipes with a cross-section of 75 mm. They are suitable for connecting a shower cabin, bidet and washbasin to a public sewer system. They are characterized by a fairly high throughput.
For domestic wastewater, products with a diameter of 50 mm will be sufficient. They are light, flexible and resistant to high temperatures (hot water) and chemicals (in case of cleaning the system chemically). To connect the toilet, it is better to take products with a cross-sectional size of 100-110 mm. They will withstand strong pressure because they are particularly durable.

Recommendations for installing sewerage from plastic pipes with your own hands
The sewer system in old buildings was primarily made of cast iron. Despite the practicality of this material, sooner or later it needs to be replaced. For the construction of modern risers, more durable and lightweight materials are used.
Helpful advice! When replacing the pipeline, it is possible to organize ventilation, which was absent in old-type systems. This way, you will be able to eliminate unpleasant sewer odors that may enter the room.
Experts even recommend refusing to use galvanized products, whose lifespan is no more than 10 years, and giving preference to polyvinyl chloride or polypropylene products. The shelf life of polymer elements is 30-50 years.
For dismantling old sewer You will need the following tools:
- large screwdrivers to remove small parts from the system;
- grinders with a metal disc;
- plastic film to cover the pipe opening at the cut;
- nail puller and chisel;
- funds personal protection(glasses, gloves, apron);
- hammer and perforator;
- scrap and grinding machine.
How to make the transition from a cast iron pipe to a plastic sewer: dismantling the old system
First you need to indicate the necessary indents. The first mark is placed at a distance of 10 cm from the ceiling level, and the second mark is placed at a distance of 80 cm from the tee. In the marked areas you need to make cuts using a grinder, with a depth of half the cross-section of the pipe. Place a chisel on the top cut and hit it with a hammer.
A similar procedure must be performed from below. The hammer must be struck with force to crack the cast iron pipe so that the middle section can be removed.
The section of pipe coming from the ceiling must be covered with plastic film.
The lower part of the system consists of a tee and other connecting elements. To dismantle it you will need a crowbar or a nail puller. These tools are necessary to loosen the fixation zones. Once this is done, you can remove the . In some cases, you cannot do without using a hammer drill. It allows you to remove the cement that holds the fasteners in place.
You can use a screwdriver or chisel to chip away the cement. After this, the tee is removed. If this procedure fails, you can use a grinder equipped with a disk designed for working with metal surfaces to cut the fitting. In this case, you should step back from the socket by about 3 cm. After dismantling the connections, you should thoroughly clean the areas where they are located from dirt, and then treat the surface with a grinding machine.
Helpful advice! Before starting work, you must notify your neighbors, since you cannot use the toilet or bathroom while the pipeline is being replaced. Otherwise, water from the upper floors will flow into the room and flood the neighbors below. For the same reason, all work must be carried out as quickly as possible.
Instructions for installing sewerage from plastic pipes
For execution installation work You will need the following tools and materials:
- pipes with a cross-sectional size of 110 mm;
- outlet tee;
- rubber cuffs designed to seal and secure the fasteners between the PVC pipe and scraps of the cast iron system;
- a pipe providing a transition from a cast iron pipe to a plastic one and vice versa;
- pipe fastenings;
- soap, which will be used as a lubricant to facilitate installation of fasteners;
- vertical building level.
The process of installing plastic pipes is carried out in a similar way, only in reverse order. Into slices cast iron pipes you need to insert rubber sealing cuffs. The adapter is installed from above, the tee must be installed from below. The fixation of all elements must be as tight as possible to ensure the tightness of the sewer system. If the tee moves freely in the connection, it can be sealed using linen tape or silicone-based sealant.
Plastic pipes have been considered the natural choice for many years when replacing an old one or installing new system sewerage. Modern production is constantly improving the technology for manufacturing plastic construction products.
As a result, a wide range of high-quality materials of various shapes and diameters appeared, which caused progress in the construction of reliable, durable sewer pipelines.
External sewer pipe - diameters.
Pipes for external drainage are orange. Diameters are produced depending on the amount of wastewater 110, 125, 160, 200, 250, 300, 400 and 500 mm. The wall size starts from 3 mm, the length varies from 1.2 to 3 m. For the arrangement of urban sewer systems, a diameter of 200 mm is used.
Dimensions of internal PVC pipes.
For the installation of internal sewerage, gray pipes are used. Standard diameter sizes are 32, 40, 50, 75, 110 and 160 mm. The wall thickness is not designed for high loads, varies from 1 to 3.2 mm. Length can be 0.3, 0.5, 1, 1.5, 2 and 3 meters.
Purpose of PVC pipe and main characteristics.
The scope of application of this material depends on its physical properties. It doesn’t hurt to know that polyvinyl chloride is one of the representatives of the group of thermoplastics, which after heat treatment and even under mechanical stress they retain their shape and integrity.
The pipe production process also uses ethylene, stabilized chlorine and additives to improve properties. The main purpose of PVC pipes is their use in the sewerage system. Depending on their thickness, the scope of use and, accordingly, the type are determined.
It could be:
- internal sewerage:
- external;
- pressure system;
- gravity drain.
This classification applies to those models that have undergone appropriate processing. Non-plasticized polyvinyl chloride PVC-U has the best technical characteristics. Performance properties directly depend on technical characteristics.
As for PVC pipes, they are characterized by the following indicators:
- high level of mechanical strength, moreover, three-layer manufacturing technology and external corrugation allows it to be installed deeply;
- resistance to negative influence aggressive environment;
- a perfectly smooth wall from the inside, which prevents the retention of solid elements;
- high internal pressure, minimum 6 bar, maximum 16;
- the highest temperature of wastewater that is allowed is +65 degrees Celsius, and the minimum is -10 degrees. There are models that can withstand +90 degrees, but if this happens for a short time;
- specific gravity 2 kg per linear meter (the figure varies depending on the thickness and diameter);
- the tensile strength is 50 MPa, and the service life is about 50 years.
Pipe sizes for indoor and outdoor systems.
The dimensions of PVC pipes are determined by several parameters: diameter, wall thickness and length. Each type of sewer has its own recommended standards.
Since polyvinyl chloride pipes are manufactured according to GOST, they have strictly defined dimensional characteristics.
The table shows standard PVC sizes pipes for internal and external sewerage:
- Dн - outer diameter of the pipe,
- d - internal diameter,
- Dy - average clearance indicator,
- b - wall thickness.
According to building codes, each element of the plumbing system has its own requirements for the diameter of the pipes (according to the internal diameter):
- 25 mm - washing machines, dishwashers,
- 30-47 mm - bathroom sink, bidet,
- 38-50 mm - kitchen cabinet, bath or shower,
- 50 mm - wiring of the sewer system inside the building,
- 70-86 mm - various branches from the central riser,
- 100-118 mm - toilet, central riser,
- 150-190 mm - the section from the central riser to the city sewer system,
- 200 mm - drainage of wastewater from baths (saunas),
- 240-300 mm - drainage of wastewater from swimming pools,
- 300-1100 mm - city sewer lines.

Advantages of PVC material.
It is important to understand that PVC, water supply, wiring and sewer, have a lot of significant competitive advantages, the main of which are considered:
- An impressive service life, usually lasting at least half a century;
- There is no need to maintain an object mounted from PVC;
- The minimum weight greatly facilitates not only storage and transportation, but also installation work;
- Low cost compared to analogues made from other raw materials;
- Impossibility of clogging the structure due to the smooth internal structure details;
- Simplicity and the ability to quickly perform installation work.
The technical features of the products in question are such that their assembly does not require the use of complex tools and expensive labor: all actions that the situation requires (in some cases, even digging trenches for external sewerage) can be done with one’s own hands; connecting pipes using a socket is not is a complex process and does not require special skills.
The following two tabs change content below.
Pipes made of plastics such as polyethylene, polyvinyl chloride (PVC), polypropylene (PP) are an alternative replacement for pipelines made of metal or concrete, that is, they are intended for laying main water pipelines, sewerage and drainage systems. In addition, they can serve as protective boxes during cable lines for various purposes (fiber optics, telephone, etc.).
Plastic pipes. Advantages and disadvantages
The main advantages of using plastic pipes in comparison with metal and concrete (ceramic) pipes:
- Smooth and smooth inner surface of the pipe, which significantly reduces the coefficient of friction, thereby increasing their conductivity;
- Resistance to corrosive damage;
- Resistance to aggressive environments of a chemical or biological nature;
- Extended service life without special care measures. Up to 50 years - plastics and up to 20-25 years of operation - pipes made of other materials;
- Environmental Safety;
- Low specific gravity;
- Low cost;
- Simplicity and ease of installation work without the need for special machinery and equipment (installation is carried out using a special thermal soldering iron and mechanical scissors).
We will focus our article on the so-called red pipes - PVC pipes intended for the construction of sewers, with a diameter of 110 millimeters. Separately, we note that all plastic products undergo mandatory state standardization and have appropriate certificates depending on the direction of their application.
Pipe for sewer system
Pipes for laying sewer drains have different colors(gray, black, various shades of both), but the red sewer plastic pipe 110 (160, 200, 250) mm is especially popular for home (private) communications. This is explained by the fact that these products are able to withstand low temperatures and high soil pressure when they are laid underground.
Technical description of a sewer pipe with a diameter of 110 millimeters
The technical characteristics of a 110 mm plastic sewer pipe have the following main definitions according to GOST:
- Pipe outer diameter size;
- Nominal wall thickness;
- Minimum pressure withstand in bar for different diameters and wall thicknesses.
Pipe sizes 110 mm for sewerage according to manufacturing materials and GOST
The common size for all plastic sewer pipes is their length. It has the following gradations: sewer plastic pipe 110 mm long 50, 100, 200 and so on up to 600 centimeters.
The maximum possible length for this type of product is 12 meters.
The diameter and wall thickness of the pipe are indicated by the manufacturer in the markings on the outer surface of the pipe and depend on the material used for its manufacture. The weight of the product depends on these parameters, taking into account the length. The diameter of plastic sewer pipes starts from 25 millimeters and, depending on the material and type of pipe (smooth, corrugated), can reach:
- For smooth pipes– 630 millimeters;
- for profiled (two-layer) – 1200 mm.
The most popular in private construction of sewerage systems are pipes with a diameter of 110-160 mm.
Calculation of the buoyancy of plastic pipes for sewer systems (110 mm)
This is not the first time we have encountered absurd questions from our users. And today the leading question is: “How to calculate the buoyancy of 110 mm plastic pipes?”
The question seems absurd for the reason that the calculation of buoyancy is carried out for pipes intended for the construction of various water structures, such as pontoon crossings, landing stages, floating breakwaters and similar structures. In this case, the minimum applicable pipe diameter starts from 300 millimeters, depending on the purpose of the construction project. Moreover, there is no need to carry out this calculation for a 110 mm plastic sewer pipe due to its size and technical structure. Simply put, a bell-shaped expansion at one of its ends.
Possible (and applicable) calculations of sewer pipes relate to their capacity of conducting liquids and determining the laying angle when laying free-flow sewer lines. In such cases, the following is taken into account:
- Length of the pipeline section;

- The thickness of its pressure walls;
- Conditions for the passage of waste liquids (fecal matter).
For calculations of this type, there are special hydraulic and mechanical tables based on GOST standards.

Cuffs for sewer pipes with a diameter of 110 millimeters or more
Plumbing rubber cuffs are designed for tightly connecting individual sewer lines and connections extending from them ( washing machine, shower cabin, toilet and so on). The following types of lip seals are distinguished:
- rod cuff;
- piston cuff;
- universal cuff.
Various rubber compounds (silicon, rubber, etc.) with the addition of polyurethane are used as manufacturing materials for these products. Such compositions are distinguished by the high quality of their density, strength, while remaining elastic.
Can be used indoors or outdoors (installations). The dimensions of the cuffs correspond to the inner or outer diameter of the sewer pipe, depending on the type of installation of the cuff. Like the main products (pipes), they have a state certificate and standards (GOST).
For high-quality drainage and drainage of water, sewerage pipes are used. They differ both in material and in diametrical cross-section. It is these parameters that affect the quality and timing of the drain. The most common option is a pipe with a diameter of 110 mm. How justified this is, what pros and cons it has, as well as the nuances of installation, we will consider in this article.
Cast iron materials have been used for decades. Their service life is estimated at an average of 80 years. The positive factors of cast iron products include their durability and high degree of strength. But one cannot fail to note the shortcomings. Cast iron products are quite heavy, which makes installation work difficult. Also, the surface of cast iron has roughness, which to some extent prevents the passage of water flows and allows elements to build up. As a result, the sewer becomes clogged. And most importantly, this type of pipes has a high price.
Not so long ago, plastic pipes appeared on sale, which turned out to be a good replacement for cast iron. They, in turn, are divided into the following types:
- PVC pipes have a number of characteristics, such as the ability to use them for low temperatures, high degree of mechanical and chemical stress. But they are afraid of high temperatures. For example, the maximum temperature that the material can withstand is 400 0 C. They have different strength indicators, depending on which their scope of application is determined:
- Light level of strength, for arranging sewer pipelines that are installed at shallow depths without exerting any pressure on them.
- Co average degree Due to the strength of PVC pipes, they can be laid through small roads.
- Heavy PVC pipes are used in industry and can be laid under highways.
- Polypropylene materials. This type of material is not used for arranging external sewage systems. It is better to use them in conditions where placement in the ground is not required. Usually this is the arrangement of internal sewerage. This is due to the fact that this material differs from PVC in less rigidity, and most importantly, the possibility of damage by rodents. But it is resistant to high temperatures up to 800 0 C.
- Polyethylene corrugation. This is one of the most common types of pipes for external sewerage. Their diameter section varies from 200 mm to 800 mm. This is a fairly durable material, it can be laid to a depth of up to 15 m. It consists of two layers: an outer corrugated one, which is made of thick polyethylene, and a smooth inner one, which has a smaller thickness.
Advantages of plastic pipe
Plastic products have a number of undeniable advantages. These include:
- Corrosion resistance. Made from materials that do not react with destructive elements. The service life of plastic is less than that of cast iron, but still reaches 50 years.
- During operation, plastic pipes do not create much noise, since the smooth inner surface ensures the unhindered passage of water.
- The environmental friendliness of the material ensures safe use in domestic conditions.
- Low degree of thermal conductivity. This is a significant plus, since passing through the pipes hot water doesn't cool down.
- Plastic is highly resistant to temperature changes and pressure changes.
- They are lightweight, which greatly simplifies the installation process. You don't need them to connect them. welding work. They are connected using special parts. The connections are ultimately reliable and sealed.
- Plastic products do not require maintenance in terms of corrosion protection. There is no need to paint them. Suitable for both open use, and for closed.
Selection of wall thickness
One of the important parameters for the reliable functioning of sewer pipes is their thickness. As water passes through the drain, it exerts internal pressure on the walls. Therefore, the thickness must be such that the walls can withstand the pressure exerted on them. But it should be noted that when draining the sewer, the water flows by gravity, high pressure it does not appear on the walls, which means that significant thickness is not required.
Basically, the wall thickness of external sewer pipes is determined by their diameter. Traditionally, the thickness of pipes with a diameter of 110 mm is 3 mm. If the diametrical cross-section is 150 - 160 mm, then their thickness is about 3.9 mm. This thickness is functionally of great practical importance. For example, if the meter is 3 mm steel pipe with a diameter of 110 mm weighs 1 kg, then a thickness of 3.9 mm with a diameter of 160 mm will already weigh about 2 kg.
Concerning plastic materials, then the dependence of the thickness and diameter parameters is preserved. The manufacturing process of PVC pipes is not complicated and, if necessary, you can change the thickness of the pipes during production.
Technical characteristics of 110 mm pipe
The main components of the diametrical section are as follows:
- Internal diametrical section. This parameter is fundamental. It is according to this that all connecting elements are selected. For sewer plastic pipes 110 mm, the internal diameter is 103.6 mm.
- The nominal diameter determines the nominal value of the internal diametral section.
- Outer diameter section.
- Pipe wall thickness.
One of the main parameters is the diametrical cross-section. It is by these indicators that the scope of application of plastic products is determined. Pipes with a diameter of 110 mm are mainly used for the construction of sewage drains.
The table below will help you decide on the choice of a pipe with a diameter of 110 mm and its technical characteristics.
How to install a 110 mm pipe
The laying of sewer pipes is determined according to a certain technology. Compliance with it ensures high-quality functioning of the sewerage system. During installation, certain features should be observed and certain nuances taken into account.
Slope of the sewer system
One of the most important parameters is the slope of sewer pipes. The drainage water should flow away easily and without any obstruction. The natural process of drainage requires the construction of some slope. According to the standard, the slope is 1 cm per 1 m of pipe. To arrange the slope, markings are first made, and then fasteners are installed in accordance with the markings. The marking is done using a level, preferably a laser. First, mark a horizontal line that runs level with the drain hole on the riser. Then it rises by a number that corresponds to the distance from the riser to the original drain point.
Connection process
An important and directly main factor in the quality arrangement of a sewer system is pipe connections. The process itself is simple, but there are some nuances that ensure the reliability and tightness of the joints. Negligence in this matter can lead to the following negative factors:
- leaks;
- unpleasant smell.
In order to prevent the above defects when connecting 110 mm pipes, sealing gaskets are used, which are available in several types: single-feather, double-feather and double-feather with plastic ring. The installation of these gaskets is carried out with some differences, which should also be taken into account. For example, single-feather gaskets are usually installed, but when installing others, it is necessary to use a special lubricant. So, in order to correctly connect 110 mm sewer pipes:
- Insert the gasket into the socket. We make sure that distortions do not form. Also, you should first inspect the gasket so that it does not have any defects.
- As a lubricant, you can use available products: detergent, soap, Vaseline. The main thing is that these products do not negatively affect rubber gaskets and do not change their structure. It is difficult to predict this, so experts recommend using a specialized lubricant that is made on a silicone basis. Silicone itself cannot be used, as it is aggressive to rubber.
- After the seals are installed, all that remains is to connect the products together. During the work, we make sure that the joints are tight.
Sequence of connections
Let us clarify that 100 mm pipes are connected not only to each other. In arranging a sewer system, various fittings are used that allow turning or other bending if necessary. Here is an example of the sequence of connections of the sewer system:
- The drain system begins with a turn signal fitting, to which, with inside a flexible corrugated hose is connected, and the outer pipe is 110 mm. Many people don't use this element. Then in this case the tightness of this connection cannot be guaranteed.
- Don’t forget, when connecting the product to the fitting, a rubber gasket must be installed. We also monitor the planting depth.
- If it is necessary to arrange a branching sewer system, tee fittings are used. To change the diametrical cross-section in the sewer system, adapter fittings should be purchased.
- The last rule in the connection. All joints must be placed along the flow of water.
Rules for working with plastic pipes
Despite the apparent simplicity of assembling a sewer system made of plastic materials, there are some nuances that should be taken into account when working. First of all, prepare the tools:
- Hacksaw or pipe cutter.
- Bulgarian.
- Sandpaper for cleaning.
- Lubricant and glue for plastic pipes.
Rules for processing plastic pipes in case of cutting them:
- After cutting the pipe into two parts, it is necessary to ensure that there is a chamfer on the cut for ease of connection.
- The sections are lightly processed with a grinder and cleaned with sandpaper.
- After this, the elements are cleaned of dust, and the ends are treated with a degreaser.
- After the rubber gaskets are installed, apply a thin layer of glue to the end and insert it tightly into the fitting. For reliability when connecting, the elements can be turned a quarter turn.
When installing a sewer drain, it is necessary to carry out the work in such a way as not to return to this procedure for at least ten years. And this is quite possible if you adhere to all the tips and rules given above. Proper pipe laying is the key to the long-term functioning of the sewer system.
