Description of PPR pipe extrusion line: 1. Pipe range: Φ 20-Φ 160mm 2. Production speed: 2-20m/min 3. Output: 60-200kg/h Process flow: Raw material+master batches--mixing--vacuum feeding--material dryness--single screw extruder--color string extruder--spiral mould--calibrator--vacuum spray calibration tank--spray cooling water tank--jet printer--belt haul-off--no-dust cutter--stacker--finished product inspecting&packing Special single screw extruder for polyolefin, having high extruding velocity and effective plasticization. Separation mixing screw specialized for polyolefin. Specially designed three co-extruding die, reasonable channel, smooth outside and inside wall, and little internal stress. Producing pipe limitΦ 20-Φ 160mm, manufacture velocity up to 16 m/min. May be used to produce HDPE silicon core tube, ordinary PP-R, PE and PEX pipes. Low cost: The cost of nanometer & anti-virus pipe is merely increase 5-10% on the ordinary pipe basis. NOTE: Patent No.: 01243874. X
