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) | |

Machine features:
Inner 3-layer co-extrusion die head
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.
PPR-AL-PPR pipe cutting device:
1)Flying knife cutting machine is used when pipe diameter≤32mm.
2)Siemens servo motor driving, response rapid , it can really realize the fast cutting of small diameter pipes.
3)Different specifications and sizes, equipped with special guide sleeves
4))When customers produce 4m or 6m long straight pipes, they can achieve (cutting) accuracy with an error of ≤1mm. The signal transmission is fast, the response is sensitive, and it can really realize the fast cutting of small diameter pipes,
