Features;

1) Type: five-layer composite pipe

2) Combines the advantages of metal and plastic pipes and eliminates the  

    disadvantages of both materials at the same time 

3) Consists of overlapped or butt welded aluminum core with inner and outer layers of 

    high temperature-resistant polyethylene

4) Diffusion tight aluminum core reliably prevents oxygen or other gases from 

    permeating into the pipes, compensates and reduces snap-back forces and heat 

    expansion with changes of temperature

5) Special welding technique ensures high reliability

6) All layers are permanently bonded together by intermediate adhesive layers

7) Selected aluminum thickness to meet compressive and flexural strength 

    requirements
