This oxygen barrier pipe production machine is used to produce 3 layer type PEXa/EVOH oxygen barrier pipes. The line speed is up to 20m/min.
Unlike like oxygen barrier pipes,which are made by co-extrusion technology. The PEXa oxygen barrier pipes are produced with two separate steps. Firstly the inner PEXa pipes is made by Ram extruder, the oldest extrusion technology, known as ENGEL extrusion technology. Then coated with outer oxygen barrier layer, which is done by coextrusion technology.

Technical Date of Pipe Production Line:

1.EVOH Extruder and Adhesive Extruder

Special designed screw and barrel for EVOH material, and Glue material, having better plasticizing effort
Using ABB brand converter; Schneider electric elements, and also all China top brand driven motor and gear reducer
Extruder temperature is set and controlled by PLC with PID system, more precise and stable;
And other operation controls are all operated on the main PLC system, with alarm, sync control and protection system.

2.Coextrusion Die Head

Two layer co-extrusion die head for glue and EVOH layer coating
Special VACUUM type design, ensuring better compound of glue and EVOH layer
High quality mould steel 40Cr material, processed by imported CNC machinery;

Tip and die mould surface are chrome-painted, to reduce friction force, increase its hardness and longer its service life, also easy to clean.
3.Haul-off machines

Two sets haul-off machines are equipped; first one is to straight the pipe, and keep stable of the pipe, to avoid any vibration of the pipe while entering the die head;
Several stage of pipe straighten and guide devices equipped
Haul-off speed is controlled by ABB controller, with SYNCRONIZED function with extruder's rotation speed.
Haul-off speed ratio of two machines are set on PLC system, ensuring stable working of the system.

4.Winding machine

Siemens Servo Traversing unit, for high precision & well arranged traversing;
Tension controller equipped to adjust the coil speed
Programmable Siemens PLC System control
Coil sizes like ID and width can be adjusted; and size with laser maker for operation convenience.

5.PLC Control system:

SIEMENS PLC system, with 10.4" colorful touch control screen; Dual language;
Precise synchronous control of main machine and the auxiliary machine; Programmable and settable alarming and protection function at all levels.
Equipped with remote control system for machine fault analysis and problem solving;
Programmable and settable alarming and protection function at all levels.
Movable trolley for convenient operation;

​​
One the same pipe production line, it can produce 3 layer PEXa EVOH oxygen barrier pipes, and also can produce two layer PEXa with black anti-UV layer. If two types want to be produced, pls specify while inquiry, to make right techncial configuration accrdongly.
