Corrugated pipe from plastic - universal material
Corrugated plastic pipe is a universal material for all spheres of human activity.
She very quickly pushed aside metal and cast iron counterparts and became the leader in the consumer market due to her unique performance characteristics and economic feasibility of use. Now, corrugated plastic pipes account for one-fourth of all manufactured pipes in the world.
Due to the improvement of corrugated pipe production technology, they have gained a huge growing popularity. Corrugations account for a quarter of all pipes produced in the world.
Corrugated protective pipe, due to its great flexibility (unlike straight lines) and lightness (unlike metal and cast iron), is much more convenient when installing any systems: water supply (cold and hot), sewerage, heating and electrical installation. In addition, its use significantly reduces construction costs for the purchase of connecting materials (fittings, couplings, curly elements) and the use of special equipment for welding.
Among other advantages of a corrugated plastic pipe are its durability (50-90 years of operation), heat resistance, anti-corrosion, deformation resistance, impact resistance, the possibility of an open and closed laying method.
Corrugated polypropylene has, perhaps, one drawback - a low melting point. Therefore, in the heating and hot water supply system, its use has some limitations, and they do not provide fire-fighting water supply.
Among all types of corrugated plastic pipes, the most popular are rigid smooth, flexible corrugated, double-layer corrugated and reinforced pipes.
Characteristics of plastic corrugated pipes
The nominal outer diameter of polypropylene corrugated two-layer pipes of an annular section is 160-630 mm. They are made of plastic by screw extrusion with molding on outer surface continuous corrugation and welding of the inner layer in places of corrugated depressions.
The corrugation on the outer layer, due to its rigidity, provides excellent strength, and the polyethylene material on the inner layer, due to its smooth surface, prevents the formation of deposits in the pipe, which narrow the space inside it.
Four types of pipes are produced: with an ordinary socket, with a reinforced socket, with a socket with a groove (for connection with pipes made of other materials) and without a socket.
Plastic corrugated double-walled pipes are joined to each other with the help of couplings, sealed with sealing rings. To prevent water and debris from entering the pipe, plugs are mounted inside it.
Materials made of polypropylene do not have a harmful effect on humans and do not emit toxic substances into the environment; special precautions are not required when working with plastic.
The main purpose of plastic corrugated double-walled pipes of different diameters is the laying of wastewater drainage systems (sewer and storm water). Initially, they were only drainage, but over time, the scope of their application has fundamentally expanded: electrical engineering, construction, mechanical engineering, Agriculture- Their services cover all industries.
Protective wiring corrugated pipe
In the process of electrical installation, polypropylene double-walled corrugated pipes of different diameters are used to protect electrical wires and cables for power and signal purposes in water, in the ground, in brick and concrete walls, behind stretch ceilings, under raised floors, on overpasses and bridges. Most often used in the organization of a gas pipeline, pipeline, television, telephone, computer communication lines and electrical networks. Electrical wiring with a voltage of up to 1000 V is laid in them, the permissible depth of occurrence in the ground is up to 6 m.
The red or blue color of the outer layer of a double-walled protective tube is not accidental: red ones are used for laying high-voltage electrical networks in the ground, blue ones are used for organizing low-voltage communication networks. The inner layer of the double-walled protective tube is black and has a smooth surface for easy cable insertion.
Polypropylene double-walled corrugation is used with different types wires and cables, the diameter provided for it is 63-200 mm. In one pipe with a diameter of 200 mm, for example, several pipes with a diameter of 63 and 110 mm can be laid.
The polypropylene pipe perfectly protects the electrical wire and cable from mechanical damage, from damage electric shock, even if the wire is damaged and the ambient humidity is high, they prevent burning in the event of a short circuit. It also protects the wire from vibrations, chemical and temperature influences. Due to the dielectric property, the polypropylene material is absolutely anti-corrosive and does not require grounding.
Sewer corrugated pipe
Large-diameter polypropylene corrugated pipe is used for the construction of sewerage, drainage, drainage systems ground water(drainage) and rainfall (storm system). The maximum temperature of short-term drains expected for them is up to 100 degrees, permanent drains - up to 60 degrees.
The inner diameter of sewer corrugated pipes is 200-800 mm, length - 6 m. They are laid in open trenches and trenchless laying, transitions are organized using reinforced concrete wells. Laying and installation of corrugated pipes of large diameter does not require the use of additional structures and special equipment.
Blockages due to the smooth inner surface in the sewer are very rare.
Plastic corrugated pipes are a material that is indispensable today.
Plastic corrugated pipes are used in almost all areas of human activity. Excellent functional characteristics and economic benefits have allowed us to push similar metal products and become a leader in the relevant consumer market. Almost a quarter of the pipe products produced in the world are plastic pipes.
Pros and cons of corrugated products
Good flexibility and relatively low mass of corrugated pipe products greatly facilitate the assembly of any systems based on this product, including heating, water supply and sewerage, as well as as a sheath for electrical wires. The use of corrugated pipes significantly reduces the costs associated with the purchase of connecting fittings. The absence of the need to use welding equipment also reduces the corresponding cost item.
Other advantages of a corrugated plastic pipe include the following:
- Flawless functioning for 50-90 years.
- Resistance to influence of factors of biological type. This is especially important for fecal sewer systems where large diameter corrugated pipes are used.
- impact resistance aggressive environment of different origin and the formation of corrosion processes.
- No need for complex arrangements supporting structures(due to low weight) leads to a reduction in operating costs.
- Affordable cost for most consumers.
Plastic corrugated pipes also have disadvantages:
- Poor resistance to high temperatures. If the specified parameter of the working environment reaches +90 0 C, then the material becomes soft and begins to deform. However, in sewer systems, temperature rise is very rarely observed. Therefore, in this area, this shortcoming becomes irrelevant.
- Greater noise audibility. This drawback is especially important in panel-type houses, where the walls perfectly transmit noise and sounds. The solution to the problem is additional sound insulation with any available materials.
Varieties of corrugated plastic pipes
Plumbing products of this type are represented by a wide range and variety. The main division into types is carried out in accordance with the purpose of the products and the material of manufacture. In addition, finished products may have a specific shape, wall thickness and dimensions of the recesses. The raw material for the manufacture of plastic corrugated pipes is polypropylene (PP), polyvinyl chloride (PVC) and polyethylene high pressure(PVD).
The highest strength is characteristic of metal-plastic pipes. However, when using such products, sharp bends should be avoided, as a result of which the pipe may burst.
Modern manufacturers produce the following types of plastic corrugated pipes:
- Corrugated single-layer pipes. The products are lightweight and have good flexibility. The main application is a protective sheath for gas pipelines and cable networks.
- Corrugated two-layer hoses. They are used in the arrangement of cable ducts as protection for electric cables in places with a high risk of damage.
- Two-layer corrugated pipes. Products are characterized by high strength and resistance to chemical and mechanical influences. In most cases, it is used for laying sewer pipelines (read: "").
- Corrugated electrical pipe. Flexibility, strength and mechanical stability are characterized by average values. In order to ensure more convenient laying of cables or wires inside the pipe, at one of the production stages such pipes are equipped with a metal cable.
In addition, the following groups of corrugated pipes are distinguished:
- Light tubing. Low mechanical stability does not allow the use of such material for underground laying, so they are not laid in trenches.
- Heavy plastic corrugated pipe. Products are characterized by medium mechanical stability, so they are used when laying underground utilities.
- The pipe is corrugated superheavy. The material is characterized by high mechanical strength, which allows it to be used in the installation of pipelines in special conditions. This situation occurs when working under the canvas railway or highway.
Design features and technical parameters
Polypropylene, polyvinyl chloride and high-density polyethylene used as raw materials are considered complex polymer compounds. This explains the high reliability of plastic corrugated pipes. Differences in the molecular structure of raw materials allow finished products to have different properties.
The recesses present on the outer side of the pipe are located at the same distance from each other. This ensures the flexibility of the products and their high mechanical stability. In addition, compared to smooth polymer pipes, corrugated products have greater strength.
By making some of the pipe rings thicker, manufacturers achieve a certain rigidity of the products so that the pipes can be used for underground laying. Notches that create a corrugated structure sewer pipes, are obtained in the process of double wall polymer extrusion technology.
The result of this production method is a corrugated plastic pipe with a smooth inner surface. This ensures unimpeded movement of waste without the formation of sludge and deposits.
Among other characteristics of particular importance are the mass of the product, the diametrical section, the wall thickness and the width of the profile. The most common are corrugated plastic pipes with the following parameters:
- The outer diameter is 120 cm, the nominal bore is 103 cm, the weight of 1 meter is from 56 to 66.9 kg, the wall thickness is 5 mm.
- Outer diameter 80 cm, nominal bore 67.8 cm, linear meter weight 24.5-33.1 kg, wall thickness not less than 4.1 mm.
- Diameter 40 cm, nominal bore 34.3 cm, weight 7-8.7 kg, walls 2.3 mm thick.
- With a minimum outer diameter of 160 mm, a nominal bore of 138 mm and a pipe wall thickness of 1.2 mm, the weight of the product should be from 1.5 to 2.1 kg.
By correctly determining the necessary parameters, it is possible to ensure high-quality laying of the sewer system and its flawless functioning.
Rules for laying a plastic corrugated pipe in a trench
Equipping the entrance to the personal plot, we must not forget about the equipment of ditches. They do not allow swamping of roads, but serve as an obstacle to vehicles entering the personal plot. The solution to the problem is special drainage corrugated pipes of large diameters, laid in a ditch. Performing work according to established rules allows these products to resist heavy loads resulting from the movement of heavy vehicles.
The laying of pipe elements in dug grooves is carried out according to the following scheme:
- The side surfaces of the moat are leveled, making a slight slope of the slopes.
- Prepare the bottom for laying the drainage pipe. For this purpose, sand is poured, equipping a kind of pillow, or they form a base of reinforced concrete with a thickness of not more than 15 cm.
- Pipe products are laid on the prepared base and a layer of crushed stone up to 30 cm thick is poured.
- The entrance area is filled with waterproofing soil, for example, clay, and it is carefully compacted.
- A layer of dense geological textile is laid in order to evenly distribute the applied load over the entrance area.
When choosing a plastic corrugated pipe for laying in a ditch, you need to pay attention to its cross section. Plastic corrugated pipes of large diameter ensure the unhindered movement of rain and ground water, including periods of high intensity. It is necessary to install decorative grilles along the edges of the pipe to prevent clogging of the channel with debris, which in most cases is carried with it by flowing water. It is best to give preference to metal products, which are characterized by increased strength.
Plastic corrugated pipe has become an alternative to conventional pipe elements. The main part of the manufactured products of the new sample is characterized by high quality, reliability and durability. This makes it possible to use corrugated plastic tubular products in the arrangement of any type of sewer system.
Convenience, reliability and practicality - all this can be fully attributed to a simple, but without a doubt, brilliant invention- corrugated pipe. There are countless areas of its application - this is ventilation, air conditioning, and sewerage, but perhaps the most massively corrugated pipe is used in laying cable networks and electrical wiring. And there are many options here - both in terms of materials, cross-section, laying conditions, and in terms of the purpose of the corrugated pipe. Next, we will consider the main, most commonly used types of this inexpensive, but so useful product— electrotechnical corrugated pipe.
What is a corrugated pipe?
The corrugated pipe is a flexible tube of round section of various diameters. The cross section is a variable here. Throughout the entire length of the pipe, thin-walled sections with a smaller diameter alternate with thick-walled sections, where the diameter is, respectively, larger. Each section is responsible for its own “quality”: thick walls guarantee rigidity and protection from the strongest impacts and heavy loads, and more “delicate” sections provide flexibility and the ability to stretch in length for a fairly decent distance. At the same time, PVC, from which modern pipes for electrical wiring are made, is absolutely fireproof.
Electrical pipes are used in various types networks - both power and low current networks. All of them are characterized by a rectangular profile - this can be seen if the pipe is cut along. This corrugated pipe is especially flexible, which allows you to build electrical networks of the most diverse configuration.
Features of the electrical corrugated pipe
Corrugated pipe for electrical needs has its own distinctive features. First of all, this is the presence of a broach - a rather thin wire in the inner cavity of the pipe. It is designed to be pulled inside the wiring harnesses.
Secondly, when choosing a pipe specifically for electrical wiring, it is important to remember that only the outer diameter is given in the catalogs. In order not to be mistaken and to fit all the necessary wires, you need to add a few millimeters of “reserve” to the value indicated in the catalog. In this case, you can also proceed from the purpose of the wiring, for example:
- To organize wiring for lighting devices or a telephone network, it is recommended to use a corrugation with a diameter of 16 mm or more;
- To organize wiring for wiring accessories, the diameter must be at least 20 mm;
- Connection of junction boxes and coaxial cable it is recommended to carry out using a corrugated pipe of at least 25 mm in diameter;
- It is recommended to connect wiring from electrical panels located remotely from each other with a corrugated pipe with a diameter of 32 mm or more;
- For the organization of interfloor connections, it is better to choose a corrugated pipe of the largest diameter - up to 50 mm.
Direct laying of the corrugated pipe can be carried out in any convenient way, thanks to its incredible flexibility - both under the raised floor and in the space above false ceiling. Heavier models are designed for stationary laying - in a concrete screed, in the ground or just in the open. In this case, you can not be afraid of aggressive effects at all. environment.
Benefits of using corrugated pipe
When it comes to electrical safety in the organization of cable routes and the convenience of their repair and modernization, the corrugated pipe is simply irreplaceable. Here are just a few of its clear benefits:
- Protection of the cable and wire from mechanical impact, as a result - long uninterrupted operation of the network.
- Protection of personnel serving the network from electric shock, even if the cable insulation is broken - the corrugated pipe acts as a "second" insulation.
- Increasing the level of fire safety - the material of the pipes does not support combustion and prevents the spread of fire inside the route.
- Exceptional ease of installation and other actions performed with the pipe - no special storage, transportation and operation conditions are required.
- Optimal cost-to-durability ratio – at a relatively low cost, the service life can reach 50 years! At the same time, the use of a corrugated pipe allows additional savings on the installation of the route - since it reliably protects the cable, it may not necessarily be armored, but of a lighter design. In other words, it is much cheaper without loss of reliability and safety.
Distinctive features of drainage corrugated pipes
In addition to electrical purposes, corrugated pipes are widely and successfully used in the field of housekeeping. They are especially relevant when organizing drainage system country house. Without a plastic corrugated pipe, it is now difficult to imagine a system for draining groundwater from the basement and foundation of a house, draining a wetland, creating a landscape design with artificial hills. For these purposes, drainage corrugated pipes with special perforations already applied to them - holes for water to get inside are successfully used today. In addition to undeniable convenience and a long service life of up to 50 years, drainage pipes made of PVC, plastic or polyethylene have a number of advantages:
- The materials of modern drainage pipes are strong and durable, which means that the pipes can be laid deep enough underground, up to 10 meters;
- Drainage pipes are easy to mount and connect to each other - couplings are designed for this, which are also widely represented on the market today;
- It is also easy to cut the pipe, no special tools are needed for this - an ordinary mounting knife is enough.
The advantages of corrugated pipes, of course, are not limited to this list. Today we can say with confidence that corrugated electrical or drainage pipes have become an integral element in the construction and arrangement of residential buildings, industrial and infrastructure facilities of any level and scale.
You can buy a corrugated pipe in the cities: Samara, Novosibirsk, Tula, Kolomna, Kazan, Yekaterinburg, Belgorod, Almetyevsk, Kirov, Orenburg, Sterlitamak, Cheboksary, Ulyanovsk, Orsk, Naberezhnye Chelny, Ufa, Saratov, Tver, Moscow, St. Petersburg and other cities of Russia.
To get acquainted with the features of the organization of the drainage system in the area next to country house using a corrugated pipe, you can by watching the video:
There are large diameter pipes made of plastic, steel and metal corrugated pipes of large diameter. Steel corrugated pipes of large diameter are characterized by a large mass, which makes their installation and transportation difficult. Metal devices have low sensitivity, because of this they are prone to subsidence of the soil, they cannot be laid with a slight slope. Plants made of polypropylene can be installed in heavily polluted soils, they do not form blockages. Moreover, they have a reduced sensitivity to soil subsidence, which means that their installation can be carried out at a slope. Therefore, when choosing a pipeline of large diameter, pay your attention to devices made of polypropylene. These structures have a longer service life (up to 100 years) and are suitable for any soil.
When choosing pipes, pay attention to the pipes of the Serbian company Pragma, they have the highest impact resistance. You can find any fittings for them, it will do. You can also purchase Korsis pipes, which are made in Russia. Some models of this company can be installed at a depth of 15 m. Pestan structures, in turn, are not susceptible to corrosion and underground decay.
