PERT/EVOH oxygen-barrier pipe, which is a new Wpe pipe for cold water. Hot water and floor heating pipe.
With very low infiltration of Oxygen (0.02mol/m. S. KPa). It can combine the advantages of EVOH omo PERT pipes.
As the picture shows, the outer layer is EVOH, the inner layer is glue/adhesive, the inner layer is PE-RT. We design the oxygen-barrier at outside layer, in order to make the quality under an effective control, but please pay attention then to make welding.
