Multilayer pipe extrusion line

Multilayer pipe extrusion line. 3 layers line for PPR / Pex tube - adhesive - EVOH and for PPR-GF (glass fiber).


Multilayer pipe extrusion line. 3 layers line for PPR / Pex tube - adhesive - EVOH with Zumbach OD control. TM 75/30 as main extruder + two 45/25 extruders for coex.

PEX and PEX pipes with oxygen barrier (EVOH) are used in places where floor heating system is required.
Tecno System manufactures PEX with EVOH and PEX pipes.

The multilayer process with glass fiber improves the material properties as the dimensional stability, the traction, compression and bending. Consists of PPR inner and outer layers and a special mixture of Glass Fiber (GF) PP middle layer. PP and Glass Fiber minimizes elongation from heat and reinforces the pipe structure.
