Characteristics of corrugations for a metal-plastic pipe. Corrugation for metal-plastic pipes Corrugated casing

Metal-plastic pipe in corrugation PEX-c HENCO 16 red 100 meters long is a pipe universal application: for drinking water supply, heating, including floor heating, gas, fuel oil, rain water and for other areas. Metal-plastic pipes consist of butt-welded aluminum pipes with inner and outer layers of polyethylene, cross-linked using electron beams. The layers are interconnected with high quality glue. The aluminum tube ensures that the tube is oxygen-tight and retains its shape. A butt weld along the entire length of the aluminum tube ensures a constant aluminum thickness. Cross-linking greatly improves the quality of polyethylene. This increases the resistance of the pipe to the effects of pressure and temperature. The pipe meets the most stringent requirements for potable water installations and is resistant to aggressive substances.

The corrugation acts as thermal insulation of round or eccentric section made of extruded PR foam with a closed cell structure. The polyethylene foam comes with a robust outer casing made of cellular polyethylene in red or blue.

Advantages of HENCO multilayer pipes:

  • one pipe for all applications;
  • high mechanical resistance due to crosslinking;
  • lack of toxicity;
  • easy to bend even at a temperature of 0 ° C;
  • high elasticity allows laying pipes in concrete;
  • no corrosion even for low and high pH values;
  • save the form.

Corrugated pipe casings are highly resistant to corrosion and have a long service life. Polypropylene and PVC do not conduct electricity. With a small wall thickness, the material is resistant to mechanical and chemical influences. Application corrugated casings for metal-plastic pipes, it is most relevant for complex piping schemes. They can be bent at different angles by changing direction. The main thing is to choose a tube of the desired diameter. For this, the distance between the pipe and the wall of the corrugation is calculated.

Products are supplied in rolls at a cost per linear meter. The minimum weight makes it easy to transport the corrugation to the construction site. Most often corrugated casings for metal-plastic pipes they are used when installing heating systems in residential premises, baths, industrial warehouses. The material easily tolerates severe frosts, protecting pipes from damage. The main advantage is the ease of installation and operation - installation can be carried out by a non-professional. You can buy corrugation in Moscow in any quantity. The price per linear meter depends on the volume of the order.

Pipes of communications for water supply and heating systems do not fit very well into the interior of the room, so it is customary to hide them under exterior trim. A lot of effort is being put into this. As a result, the desired effect is achieved and, at the same time, access is closed even if repair is necessary to the connection nodes. Now, already in the process of building the facility, the craftsmen are laying corrugations for metal-plastic pipe into walls, floors, ceilings, and even into the ground (in basements, for example). This is done for the future far before the installation of the system.

With the support of the site www.ruspetrol.ru, we decided to look into this issue.

What is a pipe-to-pipe system for?

Actually practical solution eliminates many problems:

  • Possible leaks will not cause damage to the room as a whole;
  • Simple pulling at the correct diameter will provide easy replacement of the MPT if the system needs to be repaired;
  • Inside protective cover water pipes are completely protected from mechanical damage.

Characteristics of the protective corrugation

A wide range of diameters (from 16 to 63 mm) and linear footage allow you not to think about measurements and calculations required amount.

In the coloring of protective corrugated casings, several color options are used, as a rule - red, blue and black. This is convenient for distinguishing between MP pipes when installing cold and hot water. Such a material as an insulating casing does not perform essential functions and is made of a material of known qualities.

Therefore, the manufacturer and country of manufacture does not matter - the buyer pays more attention to the price. When carrying out large-scale work, it is advantageous to immediately purchase bays of 50 m - in this case, the payment will be an order of magnitude lower.

Prices and brands

AT this moment On the market building materials This product is represented by several companies. Among them are Henco, Uni-Fitt. The average cost of a meter of corrugation, depending on the diameter and manufacturer, ranges from 10 to 50 rubles per meter. Products are sold in bays of 50 meters, but almost everywhere you can buy the necessary footage.
