Flexible water hose: how to choose a bellows hose for water


Plastic pipes made a real revolution in laying communications. If earlier metal pipes had to be replaced every 5-10 years, then with the advent of plastic pipes, utilities breathed freely. Plastic pipes do not burst if water freezes in them: they just expand, and then return to their previous shape. HDPE plastic pipe does not rust. Corrosion is the main cause of failure of metal pipes.


The production of plastic pipes from HDPE is environmentally friendly, since granules from recycled polyethylene (PE 100) are used. Technical plastic pipes do not harm the environment: low pressure polyethylene is resistant to aggressive chemical environments and does not emit harmful substances.

The use of plastic pipes.


Technical plastic pipes HDPE, due to its good wear resistance, neutral effect on them of high and low temperatures, are widely used:

  • For drainage systems of private country houses;
  • For ventilation equipment in household premises and industrial buildings;
  • For the arrangement of plumbing wells;
  • As protective covers when laying electrical and telecommunication networks;
  • For equipping free-flow sewerage systems for country houses.

HDPE pipes have a long service life, are not subject to mechanical damage and chemical attack. The use of plastic pipes is growing every day. This is facilitated by the low cost of the plastic pipe and the incredible reliability.

Technical plastic sewer pipes.


Due to the low price, plumbing pipes made of plastic are in demand for arranging gravity sewerage systems in summer cottages and country houses. Replacing traditional metal pipes for these purposes with plastic ones allows to significantly reduce the accident rate of underground utilities due to corrosion, to avoid expensive repair work with the involvement of special equipment. The price of plastic sewer pipes is a significant factor when choosing, but its exceptional reliability is much more important. Sewer plastic pipes will last much longer than steel ones, due to their high resistance to aggressive media and corrosion. They can withstand higher temperatures. Their inner surface does not need painting, it is smooth, thanks to which household waste and debris move through the pipes better, minimizing the possibility of clogging. Outdoor plastic sewer pipes from HDPE are easily assembled with each other using profile gaskets and socket joints. The outer and inner diameters of plastic pipes for sewage can vary, depending on the design flow.

Technical plastic tube for optical cable.

One of the important areas of application of technical plastic pipes is the equipment of telecommunication systems, telephone and television cables. Its inner walls have a smooth surface, so the cables laid in it do not encounter resistance. This method of laying telecommunication cables allows you to protect the communication line from mechanical damage, to protect them from the effects of an open flame (HDPE pipes are not flammable) or high temperatures.

Plastic PE pipes for electrical wiring.

With the help of plastic PE pipes, channels and protective sheaths of power cables and electrical wires are created, laid in a hidden way, outside buildings or in the ground. This method of conducting electrical wiring is used in industrial premises, warehouse complexes, office and residential buildings. The use of PE plastic pipes for electrical wiring allows you to protect the cable from external damage, prevent the possibility of electric shock to a person in the event of a cable insulation failure. After a short circuit occurs, the PE plastic pipe will prevent combustion.

Plumbing pipes made of plastic for draining.


Plumbing plastic pipes are used to equip rainwater gutters in private houses, in personal plots. The low weight and high elasticity of such pipes allow you to quickly, without much labor, mount a drainage system of any height, at any time of the year. The drain on the house, installed with the help of plastic pipes, will look beautiful and neat, it will perform well its main function - water drainage.

Ventilation plastic pipes.


Plastic pipes are used to create supply and exhaust ventilation ducts for residential buildings, industrial and public buildings. Unlike metal pipes, on which there are roughness in the area of ​​\ u200b \ u200bthe joints that slow down the movement of air flow in the system, plastic ventilation pipes are devoid of this disadvantage. Such ventilation systems are durable, mobile, not subject to corrosion, and fully comply with hygiene requirements. They avoid air mass leaks due to the absolute tightness at each connection.

Plastic pipes, like parts of other products.

A technical jacket pipe is also used as an accessory for pipelines with thermal insulation. Due to its resistance to most chemically active substances, such a plastic pipe is used to protect standard metal pipelines in many industries where there are corrosive environments. In addition, such plastic casings significantly reduce heat loss, increasing the economic benefit in the operation of pipelines.

How do you like a greenhouse made of a plastic pipe? This non-standard application of HDPE pipes is just one example of where these products can be used. Tubes and table legs are also made of plastic pipes of various lengths. Rigid or flexible pipes are used depending on the requirements for the product. A bow and even a catamaran are made from plastic pipes!

Product characteristics

Rigid PVC pipes share all the advantages of modern plastic materials, plus specific characteristics (for example, they do not spread combustion) that explain their electrical use.

PVC pipes are manufactured according to certain technical conditions (TU) and state standards (GOST). Electrical PVC rigid pipe materials come in several varieties, each of which has its own requirements developed and documented. For example, the requirements for the flammability of electrical materials are regulated by GOST 30244, the requirements for the flammability of GOST 30402.

Specifications:

  • resistance to mechanical shock is from 10 to 20 N / m, depending on the type of pipe (light, heavy);
  • protection against penetration of water or dust into the communications according to GOST 14254 from ip 65 (with high-quality installation, the degree of protection rises to ip 67, which means safe short-term immersion under water up to 1 m depth);
  • resistance 100 mOhm when exposed to voltage of 500 V;
  • material elongation at break up to 30%;
  • retain dielectric properties at a current frequency of 50 Hz and a maximum voltage of 2000 V;
  • operating temperature from - 25 to +60 degrees.

All characteristics for each type of PVC pipes are indicated in the accompanying documentation - a quality certificate. The absence of such a purchase may indicate an unscrupulous manufacturer and low quality pipe material.

The price of a plastic pipe.

Technical pipes made of plastic are cheaper than similar ones made of other materials. However, in many quality characteristics, they are not inferior to metal pipes. The use of PE granules from secondary raw materials in the production of plastic pipes significantly reduces the cost of the final product, making it possible to reduce the total cost of laying sewage systems, various telecommunications and electrical networks, drains. The low price of plastic pipes is also due to the presence of our own production with modern equipment that provides low energy costs and high productivity. You can find out how much a plastic pipe costs on our website in the section with prices (price-list) or by one of the phones. The price of a plastic pipe depends on the batch size. Wholesale plastic pipes are cheaper than with a small order.

Production of plastic pipes at a plant in the Moscow region.


Plastic pipe production at our plant in the Moscow region it is made from high-quality recycled polyethylene granules, which are pre-checked for the declared characteristics. As additional components, various ingredients are added to them that increase the resistance of the finished product to external influences, giving the technical plastic pipes the necessary performance.


The creation of plastic pipes is carried out by the method of extrusion - extrusion of finished products using special nozzles. Thanks to this technology, pipes of various cross-sections and unlimited lengths can be produced. The finished product is formed under the influence of high pressure, pressing it against the calibrating mold. Our plastic pipe factory is capable of producing any number of custom-made reservoir pipes. The shape of the pipe can be not only round: square and triangular pipes are not all that our equipment is capable of. The answer to the question: "where to buy plastic pipes of our production?" - extremely simple. You can buy our products without leaving your home. Just give us a call and the pipes will be delivered to the specified address. You can save on delivery if you pick up the pipes by self-pickup in the suburbs directly from the plant. You can also order the delivery of a plastic pipe in Moscow: if the products of the required diameter and size are available, we will deliver the required quantity on the same day.

Plastic pipes for summer cottages.


Most owners of summer cottages, country houses, cottages prefer to buy a plastic pipe for the following reasons: arrangement of an autonomous gravity drainage system, creating a drain and laying a cable. There are several advantages of using technical plastic pipes when installing a summer cottage sewage system:

  • She has no restrictions on the ground, the depth of freezing;
  • Installation of plastic pipes is carried out in a trench with a shallow depth;
  • Low weight allows to reduce the load on the supporting structures;
  • Installation of a plastic pipe in such a system is done manually (low weight), there is no need to use construction equipment;
  • Plastic downpipes not subject to corrosion;
  • Excellent tightness of all connections;
  • To clean the system, it is enough to rinse it with water.

For external drainage systems in the country, gutters and drains are pre-installed, and then a plastic pipe is mounted. For tightness, rubber gaskets are installed in all joints. Installation of such a drainage system can be carried out even in winter, and it itself can be operated for several decades. Plastic pipes for summer cottages are indispensable: only with their help can you make sewers so easily and protect external wiring. Thick-walled plastic pipes are used to create the sewage system. Both thick-walled and thin-walled plastic pipes can be used for cable laying.

Installation features

The installation of wires inside rigid PVC pipes is carried out with a slight slope, if the communications are laid in an open way. The slope is necessary to remove possible condensation inside the pipe. If the installation is carried out in a closed way, then the pipes are mounted strictly horizontally. Condensation formed is removed through junction boxes.

Installation work can be carried out at temperatures from -5 to 25 degrees. In the process of preparing for work and during them, it is required to comply with fire safety standards, personal safety measures and those established for work of this type. Certified specialists are allowed to install power grids. In production conditions, all tolerances are recorded in special journals on a daily basis.

Plastic pipes in the apartment and office.

In an office or apartment, technical plastic pipes are used for arranging electrical wiring, computer networks, and for equipping internal drains.

Due to the fact that such pipes are easily mounted in concrete walls, do not collapse with prolonged use, they are indispensable for conducting electrical cables and computer lines in the office. They can be hidden behind plasterboard slabs, suspended or suspended ceilings, in raised floors.

The use of plastic pipes for internal drains in an apartment allows you to provide reliable protection of housing from moisture, condensation and bacteria, does not create problems when repairing with the replacement of components. To connect plastic pipes, special corners are used, which ensure the tightness of the connection. To clean the drain from HDPE pipes when large debris gets into it, special plugs are used.

Plastic shaped pipes.


A technical plastic pipe does not have to be round in cross section. The so-called profile technical pipes can have various shapes. It can be a square, a triangle, a rectangle, or a rhombus. Manufacturers even sometimes have to make custom-made plastic HDPE shaped pipes in the form of a star.

Manufactured plastic profile pipes made of low-density polyethylene (HDPE) with the use of a special original nozzle for the extruder, and technology and modern equipment make it possible to produce such products for whole kilometers.

XLPE piping

One of the types of plastic water pipes is produced from low pressure polyethylene. These products are intended for various water supply systems. HDPE is an environmentally friendly material, the characteristics of which make it possible to withstand a wide range of temperatures without changing mechanical or other qualities.

This type of pipe is not afraid of exposure to ultraviolet rays, has sufficient flexibility and is resistant to frost. In general, flexible pipes for water supply are quite in demand. Due to its elasticity, the number of fittings can be reduced, which contributes to faster installation.

Joining polypropylene products is inexpensive and uncomplicated. Installation is carried out using diffusion welding or special fittings, both methods ensure tightness.

Required for work:

  • fitting;
  • rotameter;
  • insulating material;
  • shut-off valves.

Measurement and further control of the water flow occurs on the inner surface of the pipeline. Thanks to the fittings, it is possible to achieve reliable adhesion. Shut-off valves allow you to control the flow of hot or cold liquid, and the insulation serves to protect the water supply from external influences.

When welding polypropylene pipes for hot water, a seam is formed that has a strength exceeding the products themselves - this will require a special device. Depending on the characteristics of the material, they can be used in lines with a pressure of 10, 16, 20 atmospheres.

The price of pipes made of XLPE is much higher than that of other materials. As the manufacturers assure, such products will last up to a hundred years. They offer increased flexibility to accommodate long pipelines with a minimum of joints, thus reducing the likelihood of leaks.

Pipes are sold with a diameter of 1.6 to 6.3 centimeters. They are suitable for arranging hot water supply.

But at the same time, one must not forget that, like any other material, products made of cross-linked polyethylene also have some disadvantages:

  1. They must not be operated in strong sunlight.
  2. During installation, it is unacceptable to use glue for insulation - this will lead to premature wear of the product.

When installing XLPE products, it is necessary to use compression and press fittings. Flexible plastic water pipe does not require a lot of time and money for installation, since there is no need to create many joints. And this is essential if the pipeline will be of considerable length.

When installing them in an apartment building, it is recommended to find out the features of the water supply. So, if the water pressure is close to the maximum value that the pipeline will be able to withstand, this can lead to the fact that in the event of a water hammer, the system will not withstand, and this is fraught with serious consequences (read: “What is a water hammer in a pipeline - causes and effects ").

Flexible materials: Bending - Order metal processing

plastic piping for water

Therefore, you should not rush, it is better to carefully weigh all the advantages and disadvantages of the products on the market. However, it is undesirable to save on the pipeline, since high performance is a guarantee of a long service life.

Some heating schemes provide for sections of the main line that are complex in configuration. In fact, making them using steel or plastic pipes is problematic, and most often impossible. An alternative is stainless steel for heating: corrugation, corrugated pipe, corrugated pipe. What are its advantages, and what performance properties should be considered before installation?

LLC "Heating Water" offers all its own customers to purchase flexible pipelines of the highest quality and inexpensively. Here you can also order their styling.Additionally, services are provided for laying the heating main.

Flexible pipes, regardless of the material of their execution, are endowed with a number of features. Of course, they are a real lifesaver when laying or replacing pipes in difficult areas. The main advantage of such a pipeline over the others is the ability to bend it at any angle. The pipeline assembled from such elements is completely protected from corrosion. Of course, plastic products are generally not subject to rust formation, while steel products are coated with anti-corrosion compounds.

Among other things, as noted above, flexible pipes are universal, since they are able to withstand not only the pressure of cold water, but also perfectly cope with the supply of hot water. Another advantage of such products is their resistance to water hammer. Speaking about practical application, it should be said that flexible water supply elements easily allow you to include a washing machine or dishwasher in the system, the approach to which is often rather complicated. With the help of flexible pipes, it is easy to insulate the floor, providing the house with a "warm floor" system.

Polypropylene flexible pipes

Among the total number of flexible pipelines, polypropylene options are especially popular. Why is their popularity already so great? There is nothing surprising in this, polypropylene with a heat-insulating coating is able to cope with high pressures up to 10 atmospheres, while short-term pressure can reach 13 atmospheres.

A water supply system consisting of such elements does not pose any danger to people, since when high temperature water flows through it, plastic does not emit any harmful substances. Thanks to this, a person has nothing to worry about. It should be said that the minimum bending radius of a polypropylene pipe does not allow it to be rolled into a bay, therefore pipe sections are sold in 4 meter lengths.

plastic pipes for water

Among all materials, steel is the strongest and most durable. In addition, on the question of which pipes bend well, she is the clear winner. Stainless steel, from which such pipes are made, perfectly resists the formation of corrosion and rust, copes with aggressive substances, and, of course, is an environmentally friendly material. It should be noted that such a water supply system is the most expensive, but at the same time the most reliable.

Steel flexible pipes have the longest service life, which can exceed 100 years. Steel pipes withstand temperature extremes, retain their shape and do not lose their properties and qualities. Installation of a plumbing system from such elements is carried out through the use of steel fittings and sealing materials. Of the tools, the master only needs two adjustable wrenches and a sealant, which are available in every plumbing store.

Flexible materials: Types of flexible connections and service life

The main advantage of flexible pipelines is the ability to bend them at any angle without damaging the wall structure. Thanks to this, they can be used without problems when laying communications in twisted and complex areas.

In addition, flexible lines are not corrosive. If for plastic pipes corrosion is not characteristic of itself, then in the case of steel products, their surfaces are covered with anti-corrosion protective compounds.

Flexible pipes are great for laying not only cold, but also hot water systems. In addition, they are resistant to water pressure and water hammer, and also have good thermal insulation properties.

Polypropylene flexible pipes for water, heating and other communications are also very popular, which is not surprising: firstly, they have a special heat-insulating coating; secondly, they are able to function at a coolant temperature inside up to 95 ° C; and thirdly, they are resistant to very high internal pressures of the order of 10-13 atmospheres.

Such pipes are completely environmentally friendly, since polypropylene does not emit any toxic products. Their only relative disadvantage is that the permissible bending radius does not allow polypropylene products to be rolled into coils, and therefore they are produced in sections up to 4 meters long.

plastic water pipes

For the installation of polypropylene pipe products, special scissors are required for their even cutting and a soldering (welding) machine. If the required scissors are not available, then you can use a hacksaw, but after sawing the products, you will need to clean the cut surfaces from burrs.

Flexible polypropylene pipes are connected by welding (brazing). It is mandatory for the welding process to have fittings that play a connecting role between pipe products. The pipe and fitting are put on the nozzles of the welding machine and heated to the required temperature.

Steel is the strongest and most durable of all materials used for construction and repair work. This also applies to flexible steel pipes, which, along with strength, also have the property of excellent bending. Such pipes are made of stainless steel grades, and therefore another additional advantage is their anti-corrosion resistance.

These flexible modern pipelines are made of polybutene, which is significantly superior in a number of properties to polypropylene. They are as flexible, strong and heat-conducting as possible, and thanks to cross-linked polyethylene they can be welded. At the same time, Flexalen is sealed, resistant to chlorine and other chemicals.

The above qualities determine the duration of the operational life. Which can be up to 55 years old. Flexible piping for boiler room Flхalen heat resistant, chemically inert and made from environmentally friendly materials, so they can be installed in food production conditions.

Black plastic pipes HDPE.


The basic color of technical plastic pipes is black. It is in this form that black plastic pipes for sewerage for private houses, for the protection of electrical networks and telecommunications, for ventilation and air ducts, for gutters. However, the use of PE granules of various colors allows us to obtain HDPE plastic pipes of various shades. Such a color difference will be appropriate, for example, for laying electrical cables in the same wall, but going to different consumers.

Flexible plastic pipe.


The diameter of the plastic pipe determines whether the pipe is flexible or rigid. Flexible technical plastic HDPE pipes (usually of small diameter) are easy to install. With their help, you can quickly and conveniently assemble any system, be it a watercourse, protection for electrical cables or a gravity drain. Flexible plastic pipes, for example, can be bent 90 degrees (radially) without difficulty, without heating and without fractures, laying a cable route in concrete for monolithic housing construction. To cut such a plastic pipe, you can use an ordinary metal hacksaw, a simple knife or a special device. Rolled into coils, these pipes are easily transported and stored without taking up much space. Flexible plastic HDPE pipes are usually connected to fittings and accessories with clamps.

What you need to know about choosing a flexible hose diameter

The method of connecting plumbing using a flexible hose first appeared in Europe. This type of plumbing fittings include: rubber, reinforced, bellows, metal braided liners and others. Connections of gas stoves and water heater columns with a gas riser, washing machines and dishwashers, flushing cisterns and faucets with a water supply - all these types of connections are carried out using a flexible hose.

The diameter of the flexible hose for the mixer is selected in accordance with the diameter of the supplied pipes: the inner one is 8.5 mm, and the outer one is 12.1 mm.

You can choose the diameter of flexible water connections yourself by determining the water consumption of the plumbing equipment. When choosing, you can focus on the following data:

  • the diameter of the flexible connection to the toilet bowl - 8 mm;
  • hoses with a diameter of 10 mm or more are used for washing, washbasin, sink and shower cabin;
  • the diameter of the flexible connection for water 1⁄2 is used to connect the bathtubs.

Flexible eyeliner

Flexible hose diameter of 1 inch is used for:

  • hydroaccumulators in water supply and heating systems;
  • water pumps;
  • filtering systems;
  • points of water intake with a non-stationary position;
  • pipelines with limited installation space.

Large diameter flexible hose allows more water to pass through than standard hose. The parameter characterizing the amount of transported substance per unit of time is called fluidity (throughput). One of the most common diameters of flexible hoses: DN 40 and DN 50 mm.

Large diameter flexible hose is manufactured with thicker walls, which guarantees its reliability. Increasing the wall thickness makes it possible to achieve resistance to stress and mechanical stress. Flexible hose with thickened walls is used for the installation of pumps, hydrophore units, surge tanks, water heaters, heating devices and other equipment in water supply systems.

Rigid plastic pipes.

Rigid plastic HDPE pipes, unlike flexible ones, can only be used in straight sections. Large plastic pipes are generally rigid and cannot be coiled. In them, you can effortlessly, it is convenient to lay an electric cable or telephone line. At the same time, accidental damage to the insulation is completely excluded, thanks to the absolutely smooth inner surface.Very often, rigid HDPE pipes of small diameter are used to lay electrical cables along the outer (front) part of the building to power lighting systems or burglar alarms. Large-diameter plastic pipes are used in the laying of sewers. When installed in the open air, it does not disintegrate under the influence of sunlight and precipitation, does not lose its strength characteristics even in winter. Rigid plastic pipes are connected, as a rule, by gluing, soldering or welding. Also, the connection of a plastic pipe can be made using a fitting.

Metal-plastic and PVC products

This is the most popular type of flexible pipe. They are especially often used in the arrangement of water supply lines. In particular, flexible plastic water pipes are suitable for installing not only cold water lines, but also hot water supply lines.

To connect the plastic pipes together, you need special scissors or a hacksaw, sandpaper, cleaner, glue and a brush. If the cutting is done with plastic scissors, then, as a rule, additional processing of the cut places is not required. However, in the case of using a hacksaw, the end sections have to be cleaned with emery paper from irregularities and burrs.

After that, processing of the ends of the products to be joined with a cleaner is required. This facilitates softening of the surface layers and greater penetration of the adhesive.

plastic pipes for hot water

Next, the outer surface of the pipe and the inner surface of the fitting are processed with glue. After that, the pipe is inserted into the fitting and rotated internally by about a quarter of a circular arc. This contributes to a more even distribution of the glue over the surfaces of the products and greater bond strength.

The adhesive used for joining PVC pipes has some features. In particular, it somewhat dissolves the surface layers of plastic products, after which the dissolved substance, mixing with it, forms a homogeneous mass with high strength.

Flexible pipes made of metal-plastic are also found on the market of repair and construction materials, and have a number of positive characteristics, such as:

  • high resistance to pressure inside the pipe;
  • increased resistance to mechanical stress;
  • ease and ease of installation;
  • wide range of operating temperatures (from -15 to 60 ° C).

The assembly of structures from metal-plastic pipes does not present any particular difficulties and is most often carried out by means of threaded fittings.

When arranging pipelines, the following materials are used:

  • metal-plastic;
  • polyethylene;
  • polypropylene;
  • polyvinyl chloride.

The type you need can be selected by its appearance - by the color of the pipe or the colored stripe on it. For example, if the product is blue, or such a strip passes through it, then it is intended for cold water supply. Red tubular products are used to create underfloor heating, white - heating system and hot piping. The yellow pipe is for gas supply.

The plastic water pipe has many advantages:

  4. Low weight.
  5. Does not change the chemical composition of the flowing liquid.
  6. Low degree of thermal conductivity.
  7. Ease of installation.

Technical parameters are specified in the product regulations.

As for the shortcomings, there are very few of them:

  • restrictions on the temperature of the environment;
  • possible difficulties with the installation of fittings;
  • differences in the laying of different types of pipes.

flexible pipe for water

Plastic pipes for water are also widely used, for the manufacture of which aluminum is used. Multilayer metal-plastic products are ideal for both water supply. The outer and inner layers are made of plastic, and there is an aluminum layer between them.The weight of such pipes is small, and the strength is significant.

The disadvantage of metal-plastic products is the difference in the compression rates of aluminum and plastic in the event of a sharp jump in temperature. The aluminum layer has a higher speed and for this reason, the strength of the pipe joints in combination with high pressure decreases.

Rectangular plastic pipe.

Rectangular plastic pipe is one of the varieties of shaped polyethylene pipes. It is made using a special original nozzle for the extruder. The main purpose of this pipe is air ducts, although it can also be used to equip external watercourses in private houses. Due to their rectangular shape, such air ducts are easy to install, they are easily attached and rest on any surface: walls or ceiling. Rectangular plastic pipes are compactly placed in residential and industrial premises.

Round plastic tube.

Round plastic pipe is the most common product of specialized enterprises. Small diameter pipes (from 20 to 63 mm) made of this material are perfect for laying electrical cables, telephone and computer lines, they can be used to equip an internal drain in an apartment or house.

Round plastic pipes with a diameter of more than 75 mm can be used for external gutters of summer cottages and country houses. They are used to make air ducts in residential and industrial premises. Compared to metal, ventilation systems made of plastic pipes are much lighter and more durable, cheaper in price, and look more modern. They can be used in humid rooms, in places with aggressive environmental conditions.

Classification

Manufacturers offer standard smooth-walled electrical PVC pipes with a diameter of 16 to 75 mm. The minimum size is used for laying household communications, in conditions of low external loads. A diameter of 20 mm is popular for laying telephone, television, Internet cables in an open way. Materials of maximum diameter are intended for laying electrical wires in conditions of increased fire hazard, in rooms with explosive materials.

Note! Tubes from 8 mm to 250 mm in diameter can be made to order.

Standard products are dark gray. Materials of any color are made to order.

Depending on the wall thickness and resistance to loads, according to GOST 18599-83, rigid PVC pipes are divided into 4 categories, each of which has its own marking. Namely:

  • T - heavy;
  • C - medium;
  • SL - medium-light;
  • H - non-standard.

We recommend that you familiarize yourself with: Why cast iron sewer pipes are still popular

smooth rigid pipes

Standard lengths are 2, 3 or 6 meters, with a tolerance of 50 mm. New pipes are laid in bundles, packed in polypropylene film.

Technical non-pressure plastic pipes.


Non-pressure plastic pipes are used for external sewerage - transportation of domestic wastewater from buildings and private houses to drain wells. They have a smooth inner surface that prevents the formation of deposits, are highly inert to microorganisms, and perfectly resist wear under the influence of aggressive media (alkali, acid, etc.). A distinctive feature of such plastic pipes is their increased elasticity, which allows them to be used even at negative temperatures, after which they take on their original shape. Another advantage is their low thermal conductivity, which does not contribute to the formation of condensation on the outer surface of the pipes. Sewerage made of non-pressure light plastic pipes is easy to install: they are connected to each other through a socket and a rubber sealing ring.
