| Features: 1) Type: five-layer composite pipe2) Combines the advantages of metal and plastic pipes and eliminates the disadvantages of both materials at the same time 3) butt welded aluminum core with inner and outer layers of high temperature-resistant polyethylene4) 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 temperature5) Special welding technique ensures high reliability6) All layers are permanently bonded together by intermediate adhesive layers7) Selected aluminum thickness to meet compressive and flexural strength requirements |
