Pert Al Pert Insulated Pipe Pert Oxygen Barrier Pipe
Pert Al Pert Insulated Pipe Pert Oxygen Barrier Pipe

The multilayer pipes PERT/AL/PERT are composite pipes that are produced by the butt welding method .They are composed of an inner and outer layer of PERT, that are bonded  by a special glue to the intermediate layer of aluminium. By that way, a perfect oxygen barrier is accomplished, that ensures their perfect unruptured connection.

They are characterised as pipes of the century,because they combine the advantages of metal pipes (small linear expansion and high mechanical strength) with the advantages of plastic pipes (flexibility, without formation of salts inside the pipe, resistance to electro corrosion, low noise level, fast and easy installation )

The materials used to form the pipe are as follows:

Outer Layer : Polyethylene raised temperature (PE-RT) plastic coat: protects the aluminium core and allows the outer shell to be coloured without contaminating the water.

Adhesive layer : interface zone between the outer PE-RT layer and the aluminium core. Bonds the material together and prevents shear slippage.

Aluminium layer:  thin layer of lap welded aluminium which forms a 100% oxygen barrier to protect against corrosion and allows the pipe to have the 'form-stable' characteristic.

Adhesive layer : interface zone between the inner PE-RT layer and the aluminium core. Bonds the material together and prevents shear slippage.

Inner layer :inner layer of clear PE-RT. Inert and does not affect the water in any way. Allows for a smooth wall surface to reduce pressure drops for water flow.
