3 Layer PEXa EVOH Oxygen Barrier Pipe Production Line
EVOH oxygen barrier Coating Layer Making Machine

PEX-a EVOH Pipe: Suitable for underfloor heating systems and radiators.
Its manufactured by the peroxide xa cross-linking system. It has 3 layers: PEXa / adhesive / EVOH. The PEXa EVOH pipe has great flexibility and perfect homogenization of the cross-linking. It is very resistant to corrosion and chemical agents. It has an excellent thermal memory.
The EVOH barrier is a thin layer of ethyl vinyl alcohol that prevents the permeability of the pipe and diffusion of oxygen throught it. This avoids the corrosion of the metal parts, which prolongs the life of the whole installation.
Chemical resistance to building materials allows the PEXa EVOH pipe to be embeded in walls and floors without the need for protection.

Production Line Brief Introduction:

Design Features:

  • Dual working position;
  • Passive pipe uncoiling

Design Features:

  • 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

Design Features:

  • 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.

Design Features:

  • 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

Design Features:

  • Torque motor driven; Coiling speed can be easily adjusted with rotation knob
  • Coil sizes like ID and width can be adjusted; and size with laser maker for operation convenience.
