PP-R pipe making machine: 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 limitΦ20-Φ160mm, 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.
