Cobra AL-PEX Multilayered Floor Coil PipeAdvantages of AL-COBRAPEX pipe system.AL-COBRAPEX pipes are multilayer pipes with an aluminium core and represent a valid alternative to metal pipes as well as plastic pipes normally used in traditional installation systems.The technology applied to AL-COBRAPEX pipes consists of inserting a laser welded aluminium layer between two layers of high density cross linked polyethylene PE-X with an adhesive layer between each.The combination of these layers makes it possible to benefit from the advantages of both metal and plastic pipes and at the same time eliminating their typical drawbacks.
The Advantages of AL-COBRAPEX Multilayer pipes are as follows:
Impermeability to oxygen and gases in general. Shape stability during installation, for example after bending. Low thermal conductivity Lightness for transport and installation Thermal expansion lower than that of other pipe types Optimum behaviour against scale and abrasion phenomena Dielectric properties: no electric conduction Noise reduction: the inner polyethylene layer reduces the propagation of sound waves Atoxicity properties: can be used to carry liquids for alimentary use Optimum behaviour with fire thanks to the metal layer and low fume emissions in case of combustion
Reduced pressure losses thanks to the smoothness of the inner layer
