HeatWave Multi-Layer Pipe - PE-RT/AL/PE-RT

The HeatWave system multi-layer pipe consists of 5 layers. One polyethylene layer is applied to the inside and one to the outside of the welded aluminium pipe. Both PE layers are permanently bonded to the aluminium pipe by means of an adhesive layer. 

The 5-layer structure combines the advantages of plastics and metal.

Selected raw materials and a long experience in production guarantee the high quality of a technically perfected product. The pipe offers a high loading capacity at tmax 70 °C and pmax 10 bar for daily use.

Advantages of a metal pipe

- absolutely oxygen tight because of welded aluminium pipe
- form stable, no spring back forces
- low thermal expansion

Advantages of a plastic pipe

- no deposits because of the smooth inside wall.
- no corrosion because of high chemical resistance
- low weight
