Metal -plastic pipes for heating

The selection of piping material is an important factor in the efficient heating of our homes. For heating systems, metal-plastic pipes have become a popular choice because of their excellent thermal conductivity, flexibility, and durability. These pipes provide a dependable way to distribute heat throughout a home by fusing the durability of plastic with the strength of metal.

A layer of aluminum is layered between layers of plastic, usually polyethylene, to create metal-plastic pipes. Because of their distinctive design, the pipes have minimal maintenance needs and structural integrity while resisting corrosion. By improving heat transfer, the aluminum core makes it possible for heat to be distributed evenly and effectively throughout the heating system.

The flexibility of metal-plastic pipes is one of their main benefits; it allows for more flexible and easier installation. Metal-plastic pipes, in contrast to stiff metal pipes, can be bent and shaped to fit around obstructions, eliminating the need for extra fittings and lowering the possibility of leaks. This flexibility lowers labor and material costs while also streamlining the installation process.

The ability of metal-plastic pipes to withstand high pressure and temperature changes is another advantage. These pipes retain their structural integrity regardless of the temperature, guaranteeing dependable operation all year long. Because of their durability, they can be used for hot water distribution, radiators, and underfloor heating systems, among other heating applications.

Metal-plastic pipes have many practical benefits, but they also have positive environmental effects. They are a more environmentally friendly option for heating systems because they are recyclable and have a smaller carbon footprint than conventional metal pipes. Homeowners may enjoy economical and effective heating solutions while lessening their environmental effect by choosing metal-plastic pipes.

What is a metal -plastic pipe?

Polyethylene under the re-X or PE-RT brand is the polymer used to make pipes; it has undergone unique technological processing, including stitching. This idea should not be taken literally. Without delving too far into the procedure, we can say that this processing increases polyethylene’s strength and resistance to high temperatures. It would be impossible to assemble heating from metal-plastic pipes without this.

Premium metal-plastic pipe is composed of five layers. First comes polyethylene, which is used to make the internal working part, and then comes an adhesive coating. It is firmly supported by the third layer of reinforcement, which is an aluminum foil that is roughly 0.3 mm thick. It has the following objectives:

• Since all polymers tend to expand greatly when heated, aluminum, built into the design of the pipe, prevents it from heating the flowing coolant (reinforcement);
• The foil prevents the passage of oxygen with metal -plastic pipes into the coolant, which is a real enemy of the boiler plant (antidiffusion layer).

At the junction, the laser installation welds aluminum foil. The outer layer of stitched polyethylene is placed on top of the reinforcement and another layer of adhesive is applied. The end product was a fairly robust design that was also lightweight and useful.

Note: Connect the overlapped edges of the aluminum foil to lower the cost for some manufacturers. This is an indication of a medium- or low-quality product; it is preferable to use pipes for heating a private residence where VSTK produces the welding and the seam configuration is easily observable on the pipe cut.

Advantages and disadvantages

Metal-plastic pipes have replaced metal products in the market because of their many benefits. These are as follows:

• Easy installation. Metalloplastics is extremely simple, even compared to polypropylene. Tools for this need a minimum amount;
• flexibility. The pipe can be freely bend with your hands;
• small weight;
• durability. Due to the resistance of polymers to corrosion, the service life of metal -plastic pipes exceeds the viability of steel products, even galvanized;
• Small hydraulic resistance. The plastic walls do not have such roughness as metal, and therefore the resistance of friction is much lower;
• Affordable cost.

There are drawbacks to metal-polymer pipes, just like with any good product. The price of various connecting elements, or fittings, is the primary factor influencing the cost of heating systems. These components are entirely brass or bronze, unlike the pipe itself, and come in two varieties: collapsible and press. Although collapsible fittings cost more, they can be installed without the need for a specialized tool, whereas press connector installation calls for compensation ticks made specifically for this purpose.

The same fittings are the heating system’s second weak point made of metal and plastic. They inherit many of the drawbacks of metal pipes, including internal coating, hydraulic resistance, and corrosion from low-quality goods made by dishonest producers. As such, you are unable to save money on tees and knees.

There are limited-life sealing rubber rings inside the collapsible (compression) fittings. In order to ensure constant access, the heating system consisting of metal-plastic pipes with compression connectors shouldn’t be incorporated into the walls.

And the last drawback of all kinds of polymer pipes is to restrict the temperature of the coolant. With its prolonged excess, polyethylene gains increased fluidity and loses strength, and the foil layer will not be able to resist the pressure in the system for a long time, as a result of which breakthroughs will appear in the product. It should be noted here that in network water in the systems of private houses it is very rarely heated to the maximum temperature, and there can be no question of excess of it and. In general, such pipes perfectly serve in heating and water supply, in addition, the characteristics of metal -plastic make it indispensable when the waterproof waterflows are arranged in the rooms.

When it comes to home insulation and heating, metal-plastic pipes are a popular option among homeowners. These pipes are perfect for heating systems because they provide a strong blend of flexibility, durability, and thermal efficiency. Metal-plastic pipes, in contrast to conventional metal pipes, are resistant to corrosion, extending their lifespan and lowering maintenance costs. Installation is made simpler by their adaptability, particularly in confined areas and intricate designs. Moreover, they have superior thermal qualities, which guarantee effective heat transfer throughout your house. Metal-plastic pipes offer a dependable and affordable way to keep your home warm and comfortable, regardless of whether you’re building from scratch or remodeling your current heating system.

Technical characteristics of metal -plastic pipes

Prior to purchasing polyethylene pipes with aluminum reinforcement, make sure they meet the necessary requirements by carefully selecting them. By default, we believe that all of these parameters have already been determined and are known; all you have to do is select the appropriate product. The marking typically reflects every technical feature of the metal-plastic pipes. This is what they have listed:

• maximum working pressure;
• the maximum permissible temperature of the coolant;
• type of polyethylene from which the inner and outer layer of the product is made;
• Pipe diameter.

Note: The polymer types of the inner and outer layers may differ in structures made by different manufacturers.

There are no distinct types of polymer pipes made of aluminum for use with heating, hot water, or cold water. All of them have a maximum working pressure of 10 bar, which is more than sufficient for everyday tasks in residential buildings. We reserve the right to suggest that press-fittings be used to connect the pipes installed in centralized water supply systems and heat supply. The explanation is straightforward: leaks may develop on collapsible fittings years after the heating system is installed due to the large pressure drops in these networks.

Similarly, the moved environment’s maximum temperature, which typically stands at 95 oC, can be said to be the same. However, the marking does not mention another temperature threshold. This is the coolant’s maximum temperature, which varies between 110 and 120 oC depending on the manufacturer.

The pipe’s diameter is the final significant factor influencing its throughput. For metal-polymer products, the outer size multiplied by the wall thickness serves as an indicator, such as Ø 16 x 2 mm. That is, two wall thicknesses from the exterior size of 16 mm must be taken into account in order to determine the diameter of metal-plastic pipes and their throughput: 16 – 4 = 12 mm is the conditional passage Du10’s value.

The flexibility of plastic and the strength of metal combine to provide a contemporary solution for heating systems in the form of metal-plastic pipes. Because of their many advantages, these pipes are becoming more and more common in both residential and commercial heating installations. They are dependable for long-term use and less likely to leak or fail because of their resistance to high pressure and temperatures. In addition, metal-plastic pipes have a longer lifespan than conventional metal pipes because they are resistant to corrosion.

The simplicity of installation is one of the main benefits of metal-plastic pipes. Their flexibility and light weight make installation quick and easy, saving money on labor and time. Metal-plastic pipes are perfect for retrofitting old heating systems because they are easily bent and maneuvered around obstacles, unlike rigid metal pipes, which frequently require extensive cutting and welding.

Moreover, the superior thermal insulation qualities of metal-plastic pipes aid in preserving constant temperatures throughout the heating system. This guarantees the highest possible levels of comfort within the house or building while also enhancing energy efficiency. In the long run, the insulation lowers heating costs by reducing heat loss as well.

To sum up, metal-plastic pipes are a practical and adaptable option for heating systems in both commercial and residential environments. They are a desirable alternative for both homeowners and contractors due to their strength, simplicity of installation, and thermal insulation qualities. Those who purchase premium metal-plastic pipes can guarantee dependable and effective heating for many years to come, which will improve comfort and save money.
