Pipes made of PEX on the market are single layer and multilayer structures.

Multi-layer PEX pipes are represented by three species, which have the following characteristics:

-Top of a thick-walled working PPRC pipe with an adhesive mounted aluminum foil, which is covered with a thin layer of PEX,

- Connection pipe, foil and a protective layer is made with perforated holes in the foil (tube Stabi);

- Between layers of plastic core is a layer of less plastic material (pipe Faser).

Pipes of PP usually have a length of 4 m, diameter up to 125 mm. Connection pipes and fittings made of thermoplastic welding. To connect the fittings are threaded, which allows you to connect pipes from PP to the existing metal piping. Such pipes are used for hot and cold water, heating and transportation of various substances, including chemically aggressive.

When selecting from the entire arsenal of PEX pipes the best option – PEX pipes (PP). They are suitable for both cold and hot water and heating systems. High reliability is achieved by connecting these pipes diffuse welding, which allows us to obtain high-strength monolithic connection. PP pipes do not corrode, does not release harmful impurities that are durable and long lasting. To reduce the temperature of the water in the pipelines are designed elevators jetting.

In this article, the head of design and technical direction of the company
“Evro thermo” Dmitr Smilets talks about what functions and tasks
can perform the technical insulation.

Among the main objectives are the following:
# Effective reduction in heat loss. Application of high-quality insulation, with proven heat engineering parameters can significantly reduce heat loss in heating and hot water.
# Prevent condensation or freezing. This problem is most acute in the cooling system and cold water. A correctly designed, with reasonably calculated thickness, insulation eliminates condensation on the surface of the system, ensures the absence of frostbite on systems with operating temperatures below 0 ° C.
# Ensure the desired temperature at the surface of the insulation. In the working areas of the premises and served to the surface of insulation to maintain temperature for a safe location of people and creating favorable conditions for human life.
# Reducing noise from the utilities. The use of insulation can significantly reduce the noise from ventilation systems, water supply and sanitation, which is important for both residential and commercial construction.

If you talk about the other functions of technical insulation, then they are:
# Extension of the operation of engineering systems;
# Extra protection against corrosion;
# Prevent freezing of water in the PEX pipe system.
Please keep in mind that whatever the specific task is not executed technical insulation, it will always reduce loss of heat or cold, reducing energy costs.
Also, when choosing technical insulation should be aware that only properly selected material type, designed by experts wall thickness and quality installation will ensure the implementation of isolation of all functions.

Heating system

The heating system is called a system with upper
distributing, if the PEX pipe system runs directly above the thermal devices
and from the bottom – if direct and back flow located below the heating appliances.
Even there are systems with an upturned circulation, where the direct pipeline
located below the heating appliances, but the reverse – above.
In the horizontal arrangement of PEX pipes that connect
radiators, heating system is called horizontal (or wing),
in the vertical – a vertical. There are systems bifilar,
who deviate from the risers Floor wings, and fan when the radiator
throughout the floor are connected by common distribution manifold.

Double-pipe and single pipe heating system

By its design the heating system can be divided into piped and one PEX pipe. If say simple words, this is a system in which the radiators are connected or in series or parallel. Direct is when coolant passes its way from the first heat sink, and then proceeds to the next radiator. A coolant for the last radiator will be very cold, as he had squandered his heat, passing through all the radiators on link. This pipe system was used in the homes of Canada development, for this reason that most of the upper floors was very hot, and on the ground floor as a rule it was cool . With such a heating system was not possible to control the heat in the apartments, as if to block any of the radiators, then the entire system to stop work. After more years and the market of heating equipment had various pipes, which differ both in their characteristics, and design. By purchasing and installing these heaters, people began to remake the old scheme, by installing additional bypass. When closing the cutting valve, the fluid was circulating through the built-bypass. So system was designed according to another, as a consequence, new hydraulic resistance and the pumps were an additional burden to which they are not provide.V Europe pipe system never use. Because all modern systems are built in two-pipe performance, ie radiators are connected in parallel to the inlet and return line and blocking any radiators we do not violate the circulation heat transfer. If a wiring diagram radiator coolant are the same temperature. Now we have the opportunity to regulate the temperature in each room separately. For more fine tuning on the radiators are installed thermostatic heads, which open up the Taco circulation of the coolant or vice versa overlap, depending on a given temperature. My got some kind of climate control . Now is not the living rooms, we can define a low positive temperature, and in living rooms the temperature most comfortable for requirements. Give for yourself comfortable, we also obtain savings on heating costs.
