| 1,certificates:Iso,ce 2,size:DN1216-5163 3,used for hot water,cold water,gas transportation. 4,colour:yellow,red,white,black. 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 | ||||||
