MULTILAYER PIPE, D-20mm, PERT / AL / PERT, ROLL OF 100 METERS

Description of PERT-Al-PERT multilayer pipes

White multilayer tube made up of five layers: two layers of polyethylene (PERT), two layers of adhesive and one layer of aluminum.

The PERT material is a non-crosslinked polyethylene that contains additives that give it special resistance to high temperatures.

Multilayer pipes are an evolution of cross-linked polyethylene pipes since they combine the advantages of plastic pipes with the characteristics of metal pipes in the same pipe.

The advantages of plastic pipes are as follows:

Flexibility.
Lightness.
Absence of corrosion.
Ease of manipulation.
Absence of lime scale.
Long useful life.
Competitive price.
On the other hand, the properties of metallic pipes are the following:

High resistance to pressure.
Oxygen diffusion tightness.
They maintain the given shape once curved.
PERT-Al-PERT multilayer pipes are a cheaper alternative than PEX-Al-PEX multilayer pipes since the raw material used for their manufacture is cheaper and, since they do not require subsequent crosslinking, manufacturing costs are reduced. manufacturing.

Advantages of multilayer pipes compared to other plastic pipes

The incorporation of an intermediate layer of aluminum gives multilayer tubes the following advantages over plastic tubes:

Greater resistance to internal pressure.
Impermeability to oxygen diffusion.
Lower coefficient of expansion.
Longer useful life.
They keep the given shape. They are dimensionally stable.
They allow greater bends to be made.
