PPR-AL-PPR pipe production line is with 4 extruders for extruding inner&outer PPR pipe layers, inner&outer layers adhestive layers independently. The machine is using stable imported ultrasonic welder, which ensure the PPR-AL-PPR pipes can be produced in stable welding condition. The produced PPR-AL-PPR pipes are widely used in potable water supply system.
PPR-AL-PPR aluminum pipe dimensions:
| Pipe OD(mm) | Pipe Thickness(mm) | Inner PPR layer thickness(mm) | Outer PPR layer thickness(mm) | Aluminum Tape thickness(mm) | |

1)Inner 3 layer co-extrusion die head is for extruding inner PPR layer+inner adhestive layer+ Aluminum tube.
2)Mature co-extrusion and altrasonic welding technique integrated with a completely automatic control system.
3)Using Stable imported Ultrasonic Welder, which ensure the PE-AL-PE pipes can be produced in stable welding condition.
4)One-step realizes the co-extrusion of inner plastic layer and the aluminum layer. The Min aluminum strip thickness is 0.15-0.3mm, the production speed is 15m/min.
Outer 2 layers co-extrusion die head
1)The inner and outer pipes adopt a step-by-step co-extrusion process, which improves the bonding strength between the pipes,
2)avoids heat accumulation between the pipes, and ensures smoother surfaces of the inner and outer pipes.
