VESBO ALPERT (PE-RT-AL-PERT) is a multilayered composite pipe consisting of five layers. Its five layers not only combine the most advantageous properties of both metal and plastic but also avoid the disadvantages of them. An interior (300 micron) aluminum foil layer lined with inner and outer layers of PE-RT, which are bonded to the aluminum foil layer by a thermal reaction. Melted adhesive layers between the PE-RT and aluminum layer bonds the different materials firmly together.
VESBO ALPERT Multilayer Pipe consists of 5 layers:
Outer Layer: PE-RT with all properties. Protects aluminum layer against outer influences
Middle Layer: Aluminum Foil is impermeable to oxygen
Inner Layer: PE-RT with all properties. Providing the advantages and benefits of PE-RT.
Adhesive Layers: Special glue which binds the aluminum with PE-RT layers.
Since the inner and outer layers are PE-RT with all properties it provides all the advantages of PE-RT.
VESBO ALPERT has been designs to offer the advantages of a metallic pipe, such as mechanical resistance and excellent ageing and the advantages of plastic pipe like corrosion resistance, considerable lightweight, flexibility and low thermal conductivity.

Impermeability : Conventional plastic pipes have the disadvantage of insufficient barriers for oxygen diffusion, leading to corrosion in the ferrous components of a system. VESBO ALPERT pipes offer a solution to these problems, as the aluminum layer in the middle provides an optimum barrier for gases and UV-rays. The PEX surface coatings on the outside and inside prevent the metal layer to corrode.
Flexibility & Ease of installation : VESBO ALPERT pipe is more flexible and much easier to bend, it doesn’t tend to bounce back after bending, and it remains in the desired form.
Strength : Metal pipes are rigid and tend to have a higher pressure loss than polymer tubes. VESBO ALPERT pipe offers the same flexibility as a plastic pipe, due to the PE-RT layers, but has still a comparable stability like metal pipes, it has a similar strength.
Impact & Pressure Resistance : Plastic pipes usually have a relatively low impact and pressure resistance, as the material is relatively smooth and does not exhibit the same strength as metal pipes. By combining aluminum and PE-RT material, VESBO ALPEX shows a similar resistance as pure metal pipes.
Stability in Size : VESBO ALPERT stays stable and strong even in bigger sizes. Metal pipes tend to suffer the loss of stability as the diameter augments.
Burning Retardant : Plastic piping systems are relatively vulnerable to fire. In comparison with plastic pipes, ALPERT has a higher ease of ignition. VESBO ALPERT pipes reduce this risk to a significantly lower level thanks to the combination of metal and PE-RT material.
Thermal expansion : VESBO ALPERT’s one of the most important advantages over other plastic pipes is its reduced thermal expansion. Thanks to the intermediate aluminum layer that restrains the expansion rate only around one tenth of the other plastics pipe.
