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.
