Multilayer pipe for Gas and Water networks

System group, with more than 40 years of experience in the extrusion of plastic materials, offers you an excellent multilayer pipes system.

PEX-Al-PEX multilayer pipes are an evolution of PEX pipes. Multilayer pipes have two layers of cross-linked polyethylene (PEX), two layers of adhesive and an intermediate layer of aluminium.

Our PEXB-AL-PEXB multilayer pipe system combines polyethylene flexibility, chemical inertness and resistance to abrasion, with the qualities of metal, to guarantee high performance standards at temperatures up to 95°C and pressures up to 10 bar.

Here are some advantages of the multilayered pipe (PEXB-AL-PEXB), manufactured by Sami plastic:

ELECTROCHEMICAL INERTNESS
Piping systems made of Sami Plastic multilayer pipes do not conduct electricity, due to the cross-linked polyethylene lining, preventing any risk of corrosion of the metal layer due to difference of potentials.

DURABILITY
Our PEXB-AL-PEXB multilayer pipe system guarantees an extremely long service life under the recommended operating conditions.

HYGIENE
The Sami Plastic PEXB-AL-PEXB multilayer pipe system is certified for transporting potable water and alimentary fluids.

ACOUSTIC COMFORT
The double lining of cross-linked polyethylene improves the sound absorption characteristics in respect to normal metal pipes.

REDUCED THERMAL EXPANSION
Thanks to the aluminium lining, thermal expansion is limited and comparable to that of metal pipes.

REDUCED THERMAL DISPERSION
The low thermal conductivity limits heat dispersion, thus reducing the energy consumption of conditioning systems.

EXCELLENT HYDRAULIC QUALITIES
The structure of the PE inner walls of Sami Plastic PEXB- AL-PEXB multilayer pipes minimises the risk of abrasion and wear, even in very high velocity flows, while the absence of a rough surface reduces head loss.

STRENGTH
Although Sami Plastic multilayer pipes are particularly light and easy to handle, they nevertheless have excellent structural characteristics.

CORROSION-FREE
The PEXB-AL-PEXB produced by Sami Plastic has high corrosion resistance and, for this reason, is recommended for applications involving contact with particularly aggressive chemical agents, acids and bases.

EASY TO HANDLE
Sami Plastic PEXB-AL-PEXB multilayer pipes can be easily bent, even down to very small bend radius, and still retain their installed shape without requiring fittings or specials.

BARRIER EFFECT
The Sami Plastic PEXB-AL-PEXB multilayer pipe system installed in accordance with current standards is guaranteed to be totally impervious to oxygen and UVA rays. This reduces the risk of scaling and the accumulation of deposits as well as the growth of bacteria and algae to a minimum.
