The Sami Plastic PEXB-AL-PEXB multilayer pipe system combines the flexibility, chemical inertness and resistance to abrasion of polyethylene with the qualities of metal to guarantee high performance standards at temperatures up to 95°C and pressures up to 10 bar.
Piping systems making use of Sami Plastic multilayer pipes do not conduct electricity thanks to the cross-linked polyethylene lining, preventing any risk of corrosion of the metal layer due to potential difference.
The Sami Plastic PEXB-AL-PEXB multilayer pipe system guarantees an extremely long service life under the recommended operating conditions.
The Sami Plastic PEXB-AL-PEXB multilayer pipe system is certified for transporting potable water and alimentary fluids.
The double lining of cross-linked polyethylene improves the sound absorption characteristics with 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 speed fluid flows, while the absence of a rough surface reduces head loss.
Although Sami Plastic multilayer pipes are particularly light and easy to handle, they nevertheless have excellent structural characteristics.
The Sami Plastic PEXB-AL-PEXB multilayer pipe system has high corrosion resistance and, for this reason, is recommended for applications involving contact with particularly aggressive chemical agents, acids and bases.
Sami Plastic PEXB-AL-PEXB multilayer pipes can be easily bent, even down to very small radii of curvature, and retain their installed shape without requiring fittings or specials.
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.
