• Resistance to abrasion and corrosion: the inner PEX layer is corrosion-proof; it is also particularly resistant to abrasion.

• Extension: the thermal dilation values (0,026 mm/m k) are similar to those of metal pipes.

• Mechanical behaviour: the curve radius can vary from 2,5 to 5 times the pipe diameter, without altering the curve section.

Once bent, the pipe keeps the required position just like a metal pipe.

• Impermeability to oxygen: the aluminium pipe forms a total barrier against gaseous molecules, thereby preventing any risk

of corrosion due to oxygen infiltration or damage caused by exposure to UV rays.

• Smooth: the inner pipe layer has a particularly smooth surface that reduces the loss of pressure compared with metal

pipes.

• Reaction to fire: unlikely to catch fire, thanks to the inner metal layer. In any case, the density of the smoke that develops is

very low and the emissions are not harmful.

• Thermal conductivity: thermal conductivity is very low. Caloric dispersal is about 900 times less than that of copper.

• Lightweight: the G999 pipes are light and easy to transport, thanks to the low specific weight of their components. A 100 m

pipe coil with Ø 16 mm weighs about 12 kg.

• Unchanging over time: extremely high ageing resistance. Simulated ageing tests performed in the lab guarantee a working

lifetime for the pipe of more than 50 years.
