PB/EVOH Pipe
PB anti-oxygen permeated pipes are produced through composition of plastic pipe and EVOH of polymer. This kind of pipes can effectively prevent oxygen from entering piping system, protecting metal parts in system for rapid corrosion, suppressing bacterium and algae virology growth in the pipe and ensuring water quality freshly and cleanly.
