MULTILAYER PIPE, D-25mm, PEX / AL / PEX, METER

Description of PEX-Al-PEX multilayer pipes

Multilayer pipe made up of five layers: two layers, exterior and interior, of cross-linked polyethylene (PEX), a central butt-welded aluminum layer and two intermediate layers of adhesive.

Multilayer pipes are an evolution of cross-linked polyethylene pipes.

Thanks to the incorporation of the aluminum layer, multilayer pipes combine the properties of plastic pipes and the advantages of metallic pipes in the same pipe.

The properties of plastic pipes are as follows:

Flexibility.
Lightness.
Absence of corrosion.
Ease of manipulation.
Absence of lime scale.
Long useful life.
Competitive price.
For its part, the advantages of metal pipes are:

High resistance to pressure.
Oxygen diffusion tightness.
Ductility, that is, maintenance of the given shape once curved.
As we have previously indicated, the material of the inner and outer layers of multilayer pipes is cross-linked polyethylene (PEX).

The advantages of PEX-Al-PEX multilayer pipes compared to other non-crosslinked multilayer pipes are the following:

Greater tightness in the joints. The multilayer pipes made of cross-linked polyethylene in their inner and outer layers guarantee a perfect seal in the pipe-fitting joints, even at high temperatures.
Elimination of the risk of leaks. Blansol's multilayer PEX-Al-PEX pipes are designed to work at temperatures of 95ºC and with a pressure of 10 bars. In short, they withstand the harshest working conditions and, in combination with our accessories, guarantee maximum safety in the installations.
Advantages of multilayer pipes compared to other plastic pipes

Thanks to its intermediate aluminum layer, multilayer pipes have the following advantages over other types of plastic pipes:

Increased resistance to internal pressure.
Ductility. Once curved, they maintain the given shape thanks to the aluminum layer.
Oxygen diffusion tightness.
Dimensional stability thanks to its lower coefficient of expansion.
Longer useful life.
Higher flow.
