Metal-plastic pipes for heating (definition)

Metal-plastic pipes for heating — these are pipes consisting of several layers of different materials, combining the advantages of metal and plastic. They are widely used in heating systems due to their excellent performance characteristics, reliability and durability. You can choose other types of heating pipes depending on the installed equipment.

Metal-plastic pipes for heating: design

1. Inner layer - made of cross-linked polyethylene (PEX) or high-density polyethylene (PE-RT), which provides a smooth surface and resistance to corrosion and sedimentation.
2. Aluminum layer — the central layer of aluminum provides mechanical strength, dimensional stability and prevents oxygen diffusion, which is important for preventing corrosion of metal components of the heating system.
3. Outer layer — made of polyethylene (PEX or PE-RT), protects the pipe from external damage and environmental influences.
4. Adhesive layers — connect the inner, aluminum and outer layers, ensuring their strong connection and durability of the structure.

Advantages of metal-plastic pipes for heating:

• Resistance to high temperatures and pressure — the pipes can withstand temperatures up to 95°C and pressure up to 10 bar, which makes them ideal for heating and hot water supply systems.
• Flexibility and ease of installation — due to their design, the pipes are easy to bend, which simplifies their installation and reduces the number of fittings. They can be quickly and reliably connected using press fittings or crimp connections.
• Low thermal expansion — the aluminum layer significantly reduces the coefficient of thermal expansion, which prevents deformation of pipes during heating and cooling.
• Durability and corrosion resistance — the inner surface of the pipes is resistant to corrosion and does not form scale, which extends the service life of the system.

Application of metal-plastic pipes:

Metal-plastic pipes are widely used in heating systems, both in residential and commercial buildings. They are suitable for:

• Radiator heating.
• Warm floors.
• Hot and cold water supply.

In systems with solid fuel boilers a reduction in the boiler circuit temperature is required by means of hydraulic arrows, buffer capacity or three way valve, since the maximum operating temperature of these pipes is less than that required for stove-fireplace heating.

Environmentally friendly and safe:

Metal-plastic pipes for heating are safe for health and the environment, as they do not emit harmful substances and do not affect the quality of the transported water.

Metal-plastic pipes for heating are a modern, reliable and convenient solution that combines the advantages of metal and plastic, ensuring efficient and long-lasting operation of the heating system.
