Corrugated plastic pipes. Corrugated pipes

There are pipes large diameter from 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.

Convenience, reliability and practicality - all this can be fully attributed to a simple, but without a doubt, brilliant invention - a 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 - electrical 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 they are made modern pipes for electrical wiring, 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 makes it possible to build Electricity of the net the most varied 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;
• Compound junction boxes and coaxial cable is recommended to be carried 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 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 fixed laying - in concrete screed, in the ground or just in the open air. 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.
• Level up 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 conditions storage, transportation and operation.
• 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 more light construction. 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 household. They are especially relevant when organizing drainage system country house. Without a plastic corrugated pipe, it is now difficult to imagine a drainage system from the basement and the foundation of the house ground water, draining wetlands, creating 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 long term service 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 - for this purpose couplings, 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.
