Pexal® is a system composed of multilayer pipes and different fitting types that fully meet the requirements of every installation techniques and applications: from the distribution of hot and cold drinking water to centralized water supply systems, from radiator and fan heating systems to radiant floor, wall and ceiling heating and cooling systems, from compressed air systems to industrial plants.

An important trait of Pexal® multilayer pipes is that they combine the advantages of synthetic materials and in particular, those of crosslinked polyethylene, such as a high resistance to abrasion, corrosion and chemical agents, and a high standard of hygiene, with those of aluminium, such as an excellent resistance to high temperatures and pressures, dimensional stability, an unequalled barrier to oxygen and light and a low thermal expansion.

Advantages

• External layer - produced with crosslinked polyethylene PE-Xb which provides a mechanical, electrical and chemical protection of the aluminium layer, shielding it from knocks, scratches or the electrochemical aggression of water, cement and other substances contained in the ground.
• Intermediate layer - this is made of an aluminium alloy with longitudinal butt welding that guarantees a total barrier against the passage of oxygen and light and provides excellent mechanical resistance and flexibility during installation.
• Bonding layers - these are made up of a powerful adhesive that bonds the intermediate aluminium layer with the internal and external layers.
• Internal layer - the internal layer of the pipe is made up of a crosslinked polyethylene PE-Xb pipe that has been approved for the transport of consumable liquids and drinking water, It is also characterised by an extremely smooth surface that reduces pressure loss.
