Convenience, reliability and practicality - all this can be fully attributed to the simple, but without a doubt, brilliant invention- corrugated pipe. There are countless areas of its application - ventilation, air conditioning, and sewerage, but perhaps the most common use of corrugated pipe is 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 look at the main, most commonly used types of this inexpensive, but so useful product— electrical corrugated pipe.

What is a corrugated pipe?

Corrugated pipe is a flexible round tube of various diameters. The cross section is a variable quantity here. Throughout the entire length of the pipe, thin-walled sections with a smaller diameter alternate with thick-walled sections, where the diameter is correspondingly larger. Each section is responsible for its own “quality”: thick walls guarantee rigidity and protection from severe impacts and heavy loads, and more “delicate” sections provide flexibility and the ability to stretch in length to 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 you cut the pipe lengthwise. This corrugated pipe is especially flexible, which allows you to build electrical networks of a wide variety of configurations.

Features of electrical corrugated pipes

Corrugated pipe for electrical needs has its own distinctive features. First of all, this is the presence of a broach - a fairly thin wire in the internal cavity of the pipe. It is designed to tighten wiring harnesses inside.

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 make a mistake and to fit all the necessary wires, you need to add a few millimeters of “margin” to the value indicated in the catalog. In this case, you can also proceed from the purpose of the electrical wiring, for example:

• To organize wiring for lighting fixtures or a telephone network, it is recommended to use corrugated cables with a diameter of 16 mm or more;
• To organize wiring for electrical installation products, the diameter must be at least 20 mm;
• Connection of distribution boxes and coaxial cable it is recommended to use 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;
• To organize 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 false floor and in the space above the suspended ceiling. Heavier models are designed for stationary installation - in a concrete screed, in the ground or simply in the open air. In this case, you don’t have to worry about aggressive environmental influences at all.

Advantages of using corrugated pipes

When it comes to electrical safety when organizing cable routes and the convenience of their repair and modernization, corrugated pipe is simply irreplaceable. Here are just a few of its obvious advantages:

• Protection of cables and wires from mechanical stress, resulting in long, uninterrupted network operation.
• Protection of personnel servicing the network from electric shock, even if the cable insulation is damaged - the corrugated pipe acts as a “second” insulation.
• Increased level of fire safety - the pipe material does not support combustion and prevents the spread of fire inside the route.
• Exceptional ease of installation and other operations performed with the pipe - no special storage, transportation or operation conditions are required.
• Optimal ratio of cost and durability - at a relatively low cost, the service life can reach 50 years! At the same time, the use of a corrugated pipe allows you to further save on the installation of the route - since it reliably protects the cable, it does not necessarily have to be armored, but of a lighter construction. In other words, much cheaper without losing reliability and safety.

Distinctive features of drainage corrugated pipes

In addition to electrical purposes, corrugated pipes are widely and successfully used in the household sector. 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, or creating a landscape design with artificial hills. For these purposes, corrugated drainage pipes with special perforations already applied to them are successfully used today - holes for water to get inside. 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 the pipes can be laid quite deep underground, up to 10 meters;
• Drainage pipes are easy to install and connect to each other - couplings, also widely available on the market today, are designed for this;
• Cutting a pipe is also not difficult; you don’t need any special tools for this - just a regular 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.

Installation features

To organize communications, trenches are dug, their bottom is carefully prepared - cleared of large stones, sprinkled with sand, and, if necessary, compacted with concrete mixture. With the purchase of large-diameter plastic pipes, you also need to buy elements for connecting them - couplings, seals, etc. When the entire structure is assembled, it is covered with sand, compacting it in the locations of the pipes, and covered with earth without stones on top. A properly laid double-layer corrugated pipe will last for decades. They are little susceptible to rotting and corrosion, however, pay special attention to the tightness of the connecting structures. Even the slightest leak in the future can greatly reduce the life of the pipe. Be responsible when purchasing all components.

Corrugated pipes They look like tubular hollow channels made of plastic. These products are extremely flexible. That is why additional fittings are usually not required for their installation.

Corrugated plastic pipe - a universal material

Corrugated plastic pipe is a universal material for all spheres of human activity.

It very quickly pushed aside its metal and cast iron counterparts and became the leader in the consumer market due to its unique performance characteristics and economic feasibility of use. Nowadays, corrugated plastic pipes account for one quarter of all pipes produced in the world.

Thanks to improvements in corrugated pipe production technology, they have gained enormous growing popularity. Corrugated products account for a quarter of all pipes produced in the world.

Corrugated protective pipes, due to their great flexibility (unlike straight pipes) and lightness (unlike metal and cast iron), are much more convenient when installing any systems: water supply (cold and hot), sewerage, heating and electrical installations. In addition, its use significantly reduces construction costs for the purchase of connecting materials (fittings, couplings, shaped elements) and the use of special equipment for welding.

Other advantages of corrugated plastic pipe include its durability (50-90 years of operation), heat resistance, anti-corrosion, resistance to deformation, impact resistance, and the possibility of open and closed installation methods.

Corrugated polypropylene has, perhaps, one drawback - a low melting point. Therefore, its use in heating and hot water supply systems has some restrictions, 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 double-layer pipes of annular section is 160-630 mm. They are made from 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, thanks 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 a regular 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-wall pipes are joined to each other using couplings and sealed using O-rings. To prevent water and debris from entering the pipe, plugs are installed inside it.

Polypropylene materials do not have a harmful effect on humans and environment No toxic substances are released; no special precautions are required when working with plastic.

The main purpose of plastic corrugated double-wall pipes of different diameters is the laying of wastewater drainage systems (sewage and storm). Initially, they were only drainage, but over time the scope of their application has expanded significantly: electrical engineering, construction, mechanical engineering, Agriculture- their services cover all industries.

Protective electrical installation corrugated pipe

During the electrical installation process, polypropylene double-walled corrugated pipes of different diameters are used to protect electrical wires and cables for power and signal purposes in water, in soil, in brick and concrete walls, beyond stretch ceilings, under false floors, on overpasses and bridges. Most often used in the organization of gas pipelines, pipelines, television, telephone, computer communication lines and electrical networks. They accommodate electrical wiring with voltages up to 1000 V, the permissible depth in the ground is up to 6 m.

The red or blue color of the outer layer of a double-walled protective pipe 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 pipe is black and has a smooth surface for easy installation of cables.

Polypropylene double wall 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.

Polypropylene pipe perfectly protects electrical wires and cables from mechanical damage and damage electric shock, even if the wire is damaged and the ambient humidity is high, in the event of a short circuit they prevent combustion. It also protects the wire from vibration, chemical and temperature influences. Due to its dielectric property, polypropylene material is absolutely anti-corrosion and does not require grounding.

Sewer corrugated pipe

Large-diameter corrugated polypropylene pipe is used for the construction of sewerage systems, drainage systems, groundwater drainage (drainage) and rainfall (stormwater system). The expected maximum temperature for short-term effluents is up to 100 degrees, for permanent effluents - up to 60 degrees.

The internal diameter of corrugated sewer 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 large-diameter corrugated pipes does not require the use of additional structures and special equipment.

Due to the smooth inner surface of the sewer, blockages occur very rarely.

Plastic corrugated pipes are a material that you can no longer do without today.

Plastic corrugated pipes are used in almost all areas of human activity. Excellent functional characteristics and economic benefits have made it possible to push aside similar metal products and become a leader in the relevant area of ​​the consumer market. Almost a quarter of the world's pipe products are plastic pipes.

Pros and cons of corrugated products

Good flexibility and relatively low weight of pipe corrugated products greatly facilitate the assembly of any systems based on these products, including heating, water supply and sewerage, and also as a sheath for electrical wires. The use of corrugated pipes significantly reduces the costs associated with the purchase of connecting fittings. Eliminating the need to use welding equipment also reduces the corresponding cost item.

Other advantages of corrugated plastic pipes include the following:

• Flawless functioning for 50-90 years.
• Resistance to biological factors. This is especially important for fecal sewer systems where large diameter corrugated pipes are used.
• Impact resistance aggressive environment of various origins and the formation of corrosion processes.
• No need to arrange complex supporting structures(due to its low weight) leads to reduced operating costs.
• Affordable price for most consumers.

Plastic corrugated pipes also have disadvantages:

• Poor resistance to high temperatures. If the specified working environment parameter reaches +90 0 C, then the material becomes soft and begins to deform. However, it is very rare for sewer systems to experience temperature increases. Consequently, in this area, this disadvantage 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 using any available materials.

Types 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 can have a specific shape, wall thickness and recess sizes. The raw materials for the production of corrugated plastic pipes are 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, which could cause the pipe to burst.

Modern manufacturers produce the following types of corrugated plastic pipes:

• Single-layer corrugated pipes. The products are lightweight and have good flexibility. The main application is a protective shell for gas pipelines and cable networks.
• Double-layer corrugated hoses. They are used when installing cable ducts to protect electrical cables in places with a high risk of damage.
• Double-layer corrugated pipes. The products are characterized by high strength and resistance to chemical and mechanical influences. In most cases, it is used for laying sewerage pipelines (read: "").
• Electrical installation corrugated pipe. Flexibility, strength and mechanical stability are characterized by average values. In order to ensure more convenient installation 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:

• Lightweight tubular products. Low mechanical stability does not allow the use of such material for underground gaskets, so they are not laid in trenches.
• Heavy plastic corrugated pipe. The products are characterized by average mechanical stability, so they are used when laying underground communications.
• Extra heavy corrugated pipe. The material is characterized by high mechanical strength, which allows it to be used when installing pipelines under special conditions. This situation occurs when working under the canvas. railway or a highway.

Design features and technical parameters

Polypropylene, polyvinyl chloride and high-density polyethylene used as feedstock 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 outside 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 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 through 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 smooth movement of waste without the formation of sludge or deposits.

Other characteristics of particular importance include product weight, diametrical cross-section, wall thickness and profile width. The most common are corrugated plastic pipes with the following parameters:

• The outer diameter is 120 cm, nominal diameter is 103 cm, weight of 1 meter is from 56 to 66.9 kg, wall thickness is 5 mm.
• Outer diameter 80 cm, nominal diameter 67.8 cm, weight per linear meter 24.5-33.1 kg, wall thickness not less than 4.1 mm.
• Diameter 40 cm, nominal diameter 34.3 cm, weight 7-8.7 kg, walls 2.3 mm thick.
• With a minimum outer diameter of 160 mm, a nominal diameter 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, you can ensure high-quality installation of the sewer system and its flawless functioning.

Rules for laying plastic corrugated pipes in a trench

When arranging the entrance to a personal plot, we must not forget about installing ditches. They prevent waterlogging of roads, but serve as a barrier to vehicles entering the plot. The solution to the problem is special large-diameter corrugated drainage pipes laid in a ditch. Carrying out work according to established rules allows these products to resist heavy loads resulting from the movement of heavy vehicles.

Laying of pipe elements in dug grooves is carried out according to the following scheme:

• Level the side surfaces of the ditch, making a slight slope of the slopes.
• Preparing the bottom for laying drainage pipe. For this purpose, sand is poured, creating a kind of cushion, or a base of reinforced concrete no more than 15 cm thick is formed.
• Lay the pipe products on the prepared base and pour a layer of crushed stone up to 30 cm thick.
• The entry area is filled with waterproofing soil, for example clay, and it is thoroughly compacted.
• A layer of dense geological textiles is laid to evenly distribute the load across the entrance area.

When choosing a plastic corrugated pipe for laying in a ditch, you need to pay attention to its cross-section. Large diameter plastic corrugated pipes ensure unhindered movement of rainwater and groundwater, including periods of increased intensity. Decorative gratings must be installed along the edges of the pipe to prevent the channel from clogging with debris, which in most cases is carried with 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 majority of new products produced are characterized by high quality, reliability and durability. This makes it possible to use corrugated plastic pipe products when installing any type of sewer system.
