Ultrasonic overlap welding PEX-AL-PEX composite pipe production line
Plastic-Aluminum pipe is a 5 layers composite pipe, including:
Inner PEX-b layer- Inner Glue layer- Al pipe- Outer Glue layer-Outer PEX-b Layer
This kind of composite pipes have some good characteristics,such as
►no deformation under high temperature and pressure in long time;
►excellent oxygen resistance,
►high mechanical properties, sanitary, corrosion resistance,
►long termal conductivity,
►long life span etc.
PEX-b/Al composite pipes are suitable for building systems in hot&cold water or floor heating ystem. We, KAIDE factory, is the main manufacturer of plastic-aluminum pipe making machine from 19 century. Because of our excellent composite extrusion technology,our machinery can produce pipes with good distribution of each layer. This ultrasonic overlap welding PEX-AL-PEX composite pipe production line is also suitable for producing PERT-AL-PERT, PE-AL-PE pipes. According different market and different applications, the pipe's color will be different. Normally, Red color PEX-AL-PEX pipe is for floor heating system, Yellow color PEX-AL-PEX pipe is for gas delivery system, white color PEX-AL-PEX pipe is for hot/cold water system.


PEX-AL-PEX composite pipe extrusion line is using 4 extruders specially for extruding inner and outer layer PEX and Glue layer. "Multi-layers technology" is one KAIDE factory's advantaged technology with over 20 years experience. So each layer is evenly distributed.

►Imported ultrasonic welding machine for aluminum tube,welding stablely and long life span.
►By adopting the process of co-extrusion in steps for inner and external tubes, binding strength between tubes is increased, heat accumulation between tubes are avoided, hence, ensure a more smooth surface of both inner and external tubes.
►Intergrated controlling system, easy for operation, low stop ratio
►The key part of the machine are all using top brand in this industry, convenient for the after-service maintanence in future.
►Remote controlling system,easy diagnosis the fault at our factory online and save the solving time for customer
