Heating Pipe Vario Profile 16 x 2 Plus+

aluminium multi-layer composite pipe

The VarioProFile Pipe utilizes the advantages of both aluminum and plastic. Five layers are connected within the heating pipe. This guarantees an easily bendable yet dimensionally stable pipe, which is ideal for heating systems.

The innermost layer consists of polyethylene and is temperature-resistant. The mirror-smooth inner surface prevents deposits. Water flows through the pipe without resistance and with minimal pressure loss.

The profiled surface structure increases the outermost layer of the pipe by up to 15%. A larger surface area means optimized heat transfer compared to other pipes with the same diameter.

Change in length and expansion

The aluminum layer guarantees up to nine times less linear expansion than conventional plastic pipes. For this reason, the VarioProFile Pipe is ideal for surface heating and cooling. The change in length for 10 m and a temperature difference Δt 25 °C (e.g., 20 °C to 45 °C):

Low tension and good bond.

For a heating system embedded in components such as plaster, panels, or screed, it is essential how the pipes react to thermal effects, such as heat and cold.

Materials with significant expansion behavior (e.g., plastics) or large thermal expansion forces (e.g., metals) can lead to undesirable movements. The changes can cause cracks in the plaster and holes in plastic pipes due to adjacent cavities and the loosening of connections (e.g., solder joints in metal pipes).

Creep behavior

The creep behavior indicates the long-term high-temperature strength of the VarioProFile Pipe. This behavior was tested in a creep test. It is very important for heating pipes, as they can be exposed to high temperatures over a longer period. The tested creep behavior was examined for a lifespan of 50 years.
