Efield Aluminum -plastic composite pipe is consists of aluminum sheet with inner and outer
layer plastic ,tightly bonded with a special adhesive to the aluminum sheet that is
welded in overlapping and butt welding way.
It have advantage of both metal and plastic pipesit can be used in:
1.Pipes for hot and cold water pipeline system in industry and residential area.
2.Pipes for industry and chemical liquids conveying .
3.Pipes for conveying drinking water .
4.pipeline for compressed air.
5.Heating system under floor and wall.
Main Characteristics
