Equipped with polyolefin single screw extruder, it has the characteristics of high speed extrusion, acceleration, etc. Separated mixing screw and screw structure head, reasonable runner, smooth inner and outer wall of pipe. Specially designed fixed-diameter cooling method: the production range is Φ200-400mm, and the production speed is as high as 0.6-1.5 m/min. Standard designed pipe head. The spiral distribution divider ensures sufficient residence time of the melt due to the large flow space. Low melting temperature design, small internal stress of the tube grid, and smooth inner and outer surfaces. High flexibility, suitable for all polyolefin materials co-extruded, extruded two- and three-layer spiral reinforced tubes of different specifications. Optimized copper helical sizing sleeve inlet with pre-cooling device and strong suction vacuum device, suitable for high-speed extrusion of the pipe specially designed spray cooling tank. The cabinet is made of stainless steel. Rate water pump and special sprinkler head bring spray cooling. Vertical motor adjustment, up, down, left and right can be adjusted in three dimensions.
