Process flow of PPR glass fiber reinforced pipe :
Raw material +master batches→mixing→vacuum feeding→material dryness→single screw extruder→single screw extruder→single screw extruder→color string extruder→spiral coextrusion mould→calibrator→spray vacuum calibration tank→spray cooling water tank→spray-code printer→belt haul-off→no-dust cutter→pipe rack→finished product inspecting &packing
Features of PPR glass fiber pipe extrusion line:
1. Equipped with lyolefin purposed single-screw extruder; it has the characters of quick extruding, high efficiency and so on.
2. The specially designed co-extrusion die head is reasonable in flow channel, smooth in both internal and external walls, and small in internal stress.
3. Pipe diameter is among 20-160mm and production speed reaches to 18m/min...
4.One unit serves several purposes. It can produce common PP-R, Nanometer anti-bacteria pipe, PE-RT and PE-X
5. If added one co-extrusion engine and die on original base, it can produce PP-R fiberglass reinforced composite pipe.
