PLC 20mm Composite Pipe Production Line Overlap Welding

China WeiFang Kaide Plastics Machinery Co.,ltd certification
Customer Reviews
We are planning to place of the order of the 5th line from KAIDE. The machine is running very well, the most important is their after-sales service, the good company.


The high speed PP-R Pipe production line, with high running speed 40m/min, and it can save huge energy consumption, only 200KW/Ton. KAIDE is the good choice for high speed production line.


We have lines PB Pipe machine, PE-RT Pipe Machine, Oxygen barrier pipe machine. The line was deliveried since from 2007 year, they all still in good running conditions.


The high speed PE-RT production machine, 50m/min, with fully automatic winding machine,observaly improving the working efficiency, and the running performance is beyond of our expectation .

Overlap Welding Pipe Production Line

Overlap welding PEX-AL-PEX composite pipe production line


Al-PEX (PEX-Al-PEX) composite pipes are perfect combination of plastic and metal raw material. PEX-b/Al composite pipes are suitable for building systems in hot&cold water or floor heating ystem.

Pipe advantages:

  • Plastic mainly helps to retain elasticity, help against corrosion and chemical free.
  • Metal is mainly used because it has moldable features and amazing pressure strength.
  • It's also avoid the disadvantages of them.

Then how to produce this pipes?


Ultrasonic overlap welding is a typical method for making this pipe.


  • KAIDE factory, is the main manufacturer of this overlap welding multi-layers PEX-Al- PEX composite pipes  machinery from 19 century. Because of the excellent composite extrusion technology,our machinery can produce pipes with good distribution of each layer.
  • KAIDE factory's Plastic-Al pipeline can producing PEX-Al-PEX(16-63mm),PERT-Al-PERT(16-32mm), PPR-Al-PPR pipes(20-63mm). 
  • 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.

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
