Multi-layer EVOH Oxygen Barrier Pipe Line

This production line is used to produce 3-layer or 5-layer EVOH oxygen barrier pipes, such as PE-RT/EVOH, PEX/EVOH,PB/EVOH, and PA/EVOH. Several extruders are used for co-extrusion, and the gravimetric system together with synchronouscontrol system enable the extruder screw speed and line speed in closed-loop control, achieving the balanced weight per meter,shortening start-up time, saving raw materials, and making operation more intelligent and convenient After several technologicalupgrades, the current production line speed can reach 80m/min;

The patented designed EVOH pipe die head can ensure the uniform wallthickness distribution and high accuracy control of pipe size. The die headforgings is processed by quenching and tempering treatment, and manufac-tured by high-precision CNC centering, then do mirror polishing and chromeplating treatment, which ensures the long-term reliability of the die head

Vacuum tankadopts automatic vacuum degree controlsystem, to ensure the sta blity of vacuum degre; The patented designedEVOH specialized calibrator ensures the high accuracy pipe size and high-speed stable running of the production line.

Latest generation automatic pipe coiler is applied, which has the function of automatic winding, reel change, cutting, strappingand unloading, without manualintervention. The accumulator with tension control function, which provides buffering time for thereel changing and synchronous matching with the winding speed. The application of automatic pipe coiler gives strong guaran-tees for the high-speed & stable operation of production lines, and reducing labor cost while greaty improving work efficiency.

The Siemens programmable PLC control system is applied, which achieve the remote cloud contral through PC or mobileterminals, and real-time monitoring of operation status, automatically collection of warehouse information, truly realize thecomprehensive solution for industry 4.0
