Three Layers PEX-a/EVOH Pipe Production Line

Adopting simple and efficient forming process: pipe uncoiler, straighteningist tractor, heating oven, co-extrusion coating.cooling, 2nd tractor, and winding,the whole process can be synchronously completed by Siemens PLC control system.

The specialized EVOH screw has good plasticizing effect and stablemelting pressure, overcomes the difficulties of high viscosity of EVOHmaterial during extruding process, ensures the sufficient output and stable running.

The die head designed as per characteristics of adhesive and EVOH,allows for adjustable wall thickness of EVOH layer with a range of0.05mm~0.15mm. The surface of the 3 layers EVOH pipe is smooth, evenly coated, without problem of ripples, roughness, bumps, etc.

This line can produce 3 layers PEX-a/EVOH pipe, double-layer Anti-UV/PEX-a pipe, and other coating solution for various pipe.

Adopting Siemens PLC control system, can achieve many intelligent operation such as synchronous control betweenmachines, separate machine control, fault diagnosis, remote controletc. At the same time, advanced online measurement andcontrol technology is used, ensuring the plasticization quality and pipe accuracy under high-speed extrusion conditions.
