This production line is mainly used for producing HDPE large-diameter ultra-thin wall plastic pipes. Its biggest features: energy saving, high efficiency, low production cost, small footprint, large production diameter, wide wall thickness range (1mm~15mm). The produced pipe products not only have the characteristics of typical plastic pipes, but can also be used for producing insulation, anti-corrosion jacket pipe jackets, large-diameter steel pipe liners, large-diameter containers, wide width sheets, etc., with multiple uses in one machine.
