Multilayer PE-RT/AL/PE-RT pipe for underfloor heating, heating systems and sanitary systems .

It is made of composite material, made homogeneous and integral by means of a technologically advanced process with which a PE-RT pipe is made (polyethylene not cross-linked with high resistance to high temperatures), reinforced by an aluminium core, welded and externally coated by another PE-RT layer

The Alpert pipe combines the excellent characteristics of the PE-RT with the properties of the thin metal layer, which determines new benefits: 

 shape stability combined with excellent flexibility 

 contained linear expansion, similar to a metal pipe 

 oxygen barrier 100% safe 

 good thermal conductivity 

 possibility to use fittings to be stapled

Technical data:

Max temperature for short periods: 95 °C 

Coefficient of linear expansion: 0,026 mm/m °C 

Thermal conductivity: 0,45 W/m K 

Minimum radius of bending: 5 x D pipe 

Surface roughness of the internal tube: 1-1.4 μm

 Fire reaction class: EL (EN 13501-1)

Design pressure PD = 10 bar
