| 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 |
| Thermal conductivity | 0.45w/(m.k.) |
| Coefficient of heat expansion | 0.025mm/(m.k) |
| Bend radius | ≥5D(D means outside diameter) |
| Oxygen-permeability | 0 |
| Coefficient of heat roughness | 0.0004mm |
| other | Static-free,longevity |
| Following is the condition we must go by when we use it: |
| Specification | Minimum | Min pipe | long-term | working temperature | working pressure |
| burst pressure | ring strength | hydrostatic strength | ℃ |
| mm | (Mpa) | (N) | (Mpa) | cold pipe | hot pipe | (Mpa) |
