This production line is a new type of high-speed and energy-saving production line developed by Qingdao Zhaoxing Plastic Machinery based on the introduction of foreign technology and the actual situation in China combined with the experience accumulated by our company for more than ten years. It is easy to operate and practical. This production line is characterized by beautiful appearance, high degree of automation and stable and reliable production.

This unit mainly uses polyvinyl chloride or vinyl chloride as raw material to produce large-diameter double-wall corrugated pipe tubing.

Reinforced corrugated pipe is a new all-plastic reinforced twisted corrugated pipe in the current market. This pipe is made of high density polyethylene (HDPE), the pipe has a large external surface area, forming a pipe soil with pressure resistance. Fusion effect is good, enhance the tensile strength of the seam. Internal rib structure, conducive to improve the stability of the ring stiffness. Our company can produce DN300~2000mm pipes of various specifications, the length of the pipe is 6 mete

Process flow of one out of two PVC drainage pipe production line Formulation → high speed mixing → low speed cold mixing → conical twin-screw extrusion → vacuum sizing, spray cooling → hauling → trademark printing → fixed-length cutting → flaring or not flaring → inspection → packaging and storage

Configuration of polyolefin special single-screw extruder, with high-speed extrusion, high-speed speed and other characteristics. Special separated mixing screw and helical structure head, reasonable flow channel, smooth inner and outer wall of pipe. Special design of sizing cooling method: production range 50-200mm, production speed up to 0.6-1.5m/min.

Superior noise reduction and quietness of pp muffler production equipment: through the addition of special materials can adjust the density and microstructure of the pipe to absorb audible sound waves to prevent sound waves from being transmitted, noise reduction effect is better than cast iron pipe. Superior chemical resistance: the inner and outer layers of the pipe are acid resistant up to PH2, alkali resistant up to PH12, and can discharge PH2-PH12 liquids. Excellent high temperature resis
