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.
